Safety information
!
Dangerous voltages can occur on the connectors, even though the
auxiliary voltage has been disconnected.
National and local electrical safety regulations must always be
followed.
The device contains components which are sensitive to electrostatic
discharge. Unnecessary touching of electronic components must
therefore be avoided.
The frame of the device has to be carefully earthed.
Only a competent electrician is allowed to carry out the electrical
installation.
Non-observance can result in death, personal injury or substantial
property damage.
Breaking the sealing tape on the rear panel of the device will result in
loss of warranty and proper operation will no longer be guaranteed.
When a plug-in unit has been detached from the case, do not touch the
inside of the case. The relay case internals may contain high voltage
potential and touching these may cause personal injury.

Relay Configuration Tool
The Relay Configuration Tool is a standard programming system for RED 500
devices. It is used for configuring the protection, control, condition monitoring,
measurement and logic functions of the feeder terminal. The tool is based on the
IEC 61131-3 standard, which defines the programming language for relay terminals,
and includes a wide range of IEC features. The programmable logic controller (PLC)
logics are programmed with Boolean functions, timers, counters, comparators and
flip-flops. The programming language described in this manual is a function block
diagram (FBD) language.

Specification for relay configuration
Prior to starting the configuration of a product, the specification for relay
configuration is to be filled out. Separate specifications for REF 54_, REM 54_,
RET 54_ and REC 523 can be found in appendices B, C, D and E in the end of this
manual.
The purpose of the specification is to provide the technical information required for
the proper configuration of the products.

Editing the relay configurations
5.1.
Getting started
1. Start up the CAP 505 tool by double clicking the tool icon.
2. Add a new object as an empty configuration to the CAP 505 environment. For
instructions, refer to the operator’s manual for CAP 505 (see Section 1.8.
Related documents). The program opens an empty project template (see
Fig. 5.1.-1) with a toolbar at the top.
3. Build the project tree structure by inserting libraries, program organisation units
(POUs) and target-specific items to the project tree.
The project tree editor is a window in which the whole project is represented as a
tree. The project tree is illustrated with several icons. Most of the icons represent a
file of the project, and different looking icons represent different types of files. The
tree always contains 4 subtrees: Libraries, Data Types, Logical POUs and Physical
Hardware.
ProjectTree
Fig. 5.1.-1 Project tree and the four subtrees
The project tree is the main tool for editing the project structure. Editing the project
structure means inserting POUs or worksheets to the project structure, or deleting
existing ones. The editors for editing the code-body data and the variable declaration
can be opened by double-clicking the corresponding object icons.
If you edit an old project, note that saving the changes made with the
Save as command does not work as in other Windows programs. If
you want to keep the old project unchanged, save the project with a
new name before making any changes.
5.1.1.
Libraries
Before editing any worksheets of POUs, the whole project tree structure must be
build. The function block library (protection, control, measurement, condition
monitoring and standard functions) needed in the relay configuration needs to be
inserted to the Libraries subtree. For instructions on announcing libraries, refer to
the tutorial manual for the Relay Configuration Tool, see Section 1.8. Related
documents.
Before inserting a library to the project, close all open worksheets in
order to avoid confusing the I/O description of the function blocks.

1MRS750745-MUM
Configuration Guideline
The programs, function blocks (for example NOC3Low, the low-set stage of nondirectional three-phase overcurrent protection) and functions of the library can be
reused in the new project, which is edited.
The library, for example REFLIB01 for REF 54_ (see Fig. 5.1.1.-1), includes the full
set of function blocks, but only those ordered by the customer can be used in the
configuration.
If a configuration is transferred to a newer version of the product, the
library in the project must also be updated.

Fig. 5.1.1.-1
Libraries for REF 54_, REM 54_, RET 54_ and REC 523
The library version to be selected depends on the software revision of the product as
listed in the table below. The directory path to the libraries is

• Variable worksheet for variable declarations
• Code body worksheet for the configuration.
The name of each worksheet is indicated beside the corresponding icon. The
“*” symbol after the name of a worksheet indicates that the worksheet has not been
compiled yet.

The variable worksheet (for example ProtectV) is for the variable declaration. The
worksheet is automatically named by adding a “V” to the name of the POU. The
variable worksheet is not edited manually but is created by the tool.

Variable declaration worksheet
A code body worksheet (for example Protect) is for a code body declaration in the
form of an function block diagram (FBD). All configurations for the devices of the
RED 500 platform are made in the graphical FBD language.
A code body programmed in the FBD language is composed of functions and
function blocks that are connected to each other using variables, connection lines or
connectors. An output of a function block can be combined with the output of
another function block for example via an OR gate (refer to Section 6.1. General).
Connectors are objects that can be used instead of connection lines, for example
where the distance between two objects on the worksheet is long. The connectors
can only be used within one worksheet, and they are resolved by textual names.

Connectors should be used with care since the tool may not warn if a
match to a connector cannot be found (for example, the comparison
of connectors is case sensitive).
Note that visually the connectors are distinguished from variables by embedding
them with “larger than” signs, “> >”.
Connectors

Code body declaration in FBD language
Even though the tool permits adding several code body worksheets under one POU,
only one worksheet is recommended to be used per POU. If more space is needed
for a configuration, the worksheet size can be increased or the functionality can be
divided into several POUs.
Avoid creating very large configurations per POU since the RED 500 PLC
environment has an inherent limit for the number of input/output points per POU.
The limit is 511 I/O points and is consumed by called function block instances only.
Note that the limit is checked during the configuration downloading. If the
downloading fails for this reason, the user has to divide the POU into smaller units.
For example, the function block NOC3Low in Fig. 5.1.2.-4 includes 14 I/O points.
The I/O points are consumed regardless of whether they are connected or not.

Logical POUs
In the project tree editor and in the library editor, the Logical POUs subtree
represents a directory for all the POUs related to the project. The maximum of 20
POUs can be inserted to the subtree. Fig. 5.1.3.-1 shows a Logical POUs subtree

with 4 POUs; “CondMon” represents a function block, “Confirm” represents a
function, and “Measure” and “Control” are programs. The associated icon
represents the POU type.
LogicalPOUs
Fig. 5.1.3.-1
Logical POUs subtree with 4 POUs
Each POU type has specific characteristics from the programming point of view.
• A function yields exactly one data element which is evaluated from its input
parameters. In other words, a function cannot contain any internal state
information. Furthermore, a function can call other functions but not function
blocks.
• A function block (FB) can return 0,1,2.. output values and can have internal
variables. Function blocks can call any other function or function block except
itself. Multiple copies of function blocks are called instances and each instance is
given an identifier.
• Programs are specialized function blocks that can only be called by tasks.
Note that recursion is not allowed for any POU type.
The POU category is selected when a POU is inserted to the project tree. Fig. 5.1.3.2 below shows the dialog box for inserting POUs. The programming language
(FBD) for the POU and the return data type for functions are also selected here. The
PLC type and Processor type selections should be left to their default values.

InsertNewPOU

Inserting a new program POU called “Demo” which is
programmed by using the function block diagram language
At first, a POU framework is created, that is, empty POUs are inserted to the project
according to the Specification for Relay Configuration filled out prior to starting the
configuration procedure. The physical hardware must be defined before creating the
actual contents for the POUs, otherwise the predefined target-specific POUs are not
available for the programmer.
The task execution intervals recommended for function blocks must be considered
already when defining the POU framework. In general, each POU forms a functional
unit for example for protection function blocks. Some function blocks, however,
require a different task than most of the same category, and must therefore be
assigned a separate POU. For example, the task execution interval of most
protection function blocks is 10 ms but Freq1St_ requires the task of 5 ms, which is
why it usually needs a separate POU. However, if all the protection function blocks
used are associated with the task of 5 ms, no separate POU is required for Freq1St_.

Task interval
Generally, operation accuracy is increased when task speed is increased, but at the
same time, the load of the microprocessors is increased as well. Although the task
speed can be freely chosen with the tool, it is necessary to define a maximum task
execution interval for each function block. If not defined, the operation accuracy and
operate times for protection functions cannot be guaranteed.
The maximum task execution interval is based on test results and it has been used in
the type testing of the function blocks. The recommended task execution interval
quaranteed by the manufacturer can be found in technical data section in the
technical description of each function block. Furthermore, certain function blocks,
for example MEDREC16, must be tied to the task given by the manufacturer in order
to enable the operation of these function blocks. For more information about the task
execution intervals of function blocks, refer to the introduction chapter in the
Technical Descriptions of Functions CD-ROM, see Section 1.8. Related documents.
For microprocessor loads, refer to Section 5.5. Downloading the configuration.
According to the standard, the Relay Configuration Tool offers a possibility to
define the tasks on two different levels:
1. Each program organisation unit (POU) can be tied to a separate task.
2. Separate function block inside a POU can be tied to any task.

Protection & Control Terminals

RET 54_, REC 523
Configuration Guideline
However, the second alternative is not supported in the RED 500 environment; if a
separate function block inside a POU is given a separate task definition, it is ignored
when transferred to the device. This means that when the function blocks are being
placed in different POUs, not only the category of the function (protection, control,
and so on) but also the maximum task execution interval should be considered, since
all function blocks inside a POU run at the same speed.
Define the task execution interval for each task by selecting a task and by selecting
Edit > Insert; click the Settings button in the opening dialog. For example, the task
execution interval for Task1 in the figure below is defined as 10 ms, which means
that the program Prot_Me is run 100 times per one second. The maximum number
of tasks with different intervals is 4.
The tool automatically modifies the task setting if the set network
frequency is other than 50 Hz (see the Network Frequency text box
in Fig. 5.1.4.2.-4). For example at 60 Hz, 10 ms becomes 8.333 ms.
interval
Fig. 5.1.4.4.-3 Setting the task execution interval for a program
If there is a need for several different tasks that control the same output relay, it is
recommended that the output relay is controlled directly in the fastest task and other
control commands are brought to that task via global variables.
Example:
Some protection function blocks can be run in the 5 ms task, some in the
10 ms task and some even using the 100 ms task. Still, all these function
blocks use the same output relay.
Another way to avoid also the software delays when communicating between the
different tasks is to use a separate output relay for each protection task.
Example:
The trip signal from the 5 ms task is connected to High-Speed Power Output
1 and the trip signal from the 10 ms task to High-Speed-Power-Output 2. The
outputs can then control the same opening coil of the circuit breaker.

Declaring variables
The validity range of the declarations that are included in the declaration part should
be “local” to the POU in which the declaration part is contained. However, variables
that are declared to be “global” are only accessible to a POU via a

Fig. 5.2.-1 Local and global variables
The figure above illustrates the how variable values can be communicated among
software elements either directly or via global variables.
Variable values within a program can be communicated directly by connecting the
output of one program element to the input of another, or via local variables, such as
the variable “y” illustrated in the upper-left corner of the figure above.
In the same configuration, variable values can be communicated between programs
via global variables, such as the variable “x” illustrated in Configuration C in the
figure above. In such a case, make sure that the global variable is only written from
one location in the project. The global variable can still be read from several
locations.
According to the IEC 61131-3, all the variables that have no explicit initializer are
initialized with a data-type dependent default value. Despite of this, it is always
recommended that the initial value is given explicitly. Naturally, the value to which
each variable should be initialised depends on the logical function of the program .

Especially the initial values of global variables are logically significant for the
program. The user cannot choose the order in which tasks are initialised. This means
that if a task reading a global variable is initialized before another task gives the
variable its first value, it is important that an appropriate initial value has been
selected for the global variable.

The physical contacts are defined in the Global Variables worksheet (Fig. 5.2.1.-1).
Declarations for the physical contacts are automatically defined when the correct
hardware version of RE_ 54_ is selected. Declarations for the analog channels are
created after the analog channel settings defined in the resource settings dialog box
have been approved.
The textual names of the inputs and outputs, for example BIO2-7_BI10IV (see the

Compiling project
In the Relay Configuration Tool’s Make menu, select the command Build Project
to compile the whole project for the first time after editing. This means compiling
all POUs, global variables, resources and so on.
In the Make menu, use the Make command to compile the worksheets that have
been edited. The changed worksheets are marked with an asterisk, “*”, in the project
tree editor. The Make command is the standard mode for compiling and should
normally be used when you have finished editing.
It is recommended that the Build Project command is given once more
just before downloading the configuration to the product.
In the Relay Configuration Tool you can view the execution order of the different
functions or function blocks in your worksheet. The execution order corresponds to
the intermediate PLC code created while compiling. Note that the execution order
can only be seen if you have already compiled the worksheet by using the menu
command Make > Compile Worksheet.
5.4.
Add-on protocol
If an add-on protocol is used, the protocol mapping must be created by using the
Protocol Mapping Tool (PMT). For more information, refer to the documents in
Section 1.8. Related documents.

modified by using the Protocol Mapping Tool. In earlier releases, the
protocol interface can be modified by using the Protocol Editing
Tool. These tools are included in CAP 505. For more information on
the REC 523 protocols, refer to the technical reference manual of
REC 523 (see Section 1.8. Related documents).
5.5.
Downloading the configuration
After the configuration has been built and succesfully compiled in the Relay
Configuration Tool and the MIMIC configuration has been designed, the project can
be downloaded to the device.
57
REF 54_, REM 54_, Protection & Control Terminals
RET 54_, REC 523
1MRS750745-MUM
Configuration Guideline
The parts of the project to be downloaded are selected via a dialog box. The MIMIC
configuration and the Relay Configuration Tool project can be downloaded
separately.
The project can also be downloaded separately as a compressed file.
This enables later uploading of the project from the device. The
compressed file is automatically created if the check box RCT
project has been selected (see Fig. 5.5.-1).
The target device has an inherent limitation over the size of a stored project file. If
this is exceeded, the tool interrupts the downloading and issues a warning.
It is useful to include some information of the project in the file by
giving, for example, the name of the designer, the date and the version
or other description of the configuration. To add project information,
select File > Project Info in the Relay Configuration Tool.
Add-on protocols (for example Modbus and IEC 60870-5-103) of the relay terminal
are activated in the relay according to Add-On protocol selection in object
properties.

REM 54_ or RET 54_ display, and a message appears in the CAP 505. The exceeded
CPU load can also be read via the parameter after a failed downloading, that is, the
load value can be for example 115%.
Whenever downloading fails, a storing sequence cannot be started but the device
must be reset before next downloading. Moreover, the device is automatically reset
after a failed downloading when the download dialog box in the Relay Download
Tool is closed.
Note that the exceeded CPU load must be checked before resetting; after the device
is restarted, the parameter Config. capacity only shows the load of the
previous configuration that was downloaded succesfully and has become valid
again.

REF 54_ Release 2.5, RET 54_ and REC 523 revision F additions
The REF 54_ Release 2.5 and later, REC 523 revision F and RET 54_ includes the
following functions supported by the Configuration Download Tool:
• Relay and configuration tool compatibility checking
• Improved configuration error reporting
• Easier identification of the relay configuration
Compatibility checking
The download tool verifies that the connected relay matches the type and revision
set in the relay configuration. If a mismatch occurs, downloading is not allowed.

specific requirements regarding analog channel configuration and task cycle time
are fulfilled. If errors are detected, a list containing all errors is shown. The list
contains the name of the function block that reported the error and a plain text error
description.
The error list can be copied to the clipboard and printed by using any text
editor for easy reference when correcting the configuration.

A parameter is also included to identify the bay in which the configuration is used.
The title and author are set from the File > Project info menu of the Relay
Configuration Tool.
The bay name is taken from the bay object in the project structure navigator or from
the protection and control object, if no bay object is used.
The last download/modification date parameters are set automatically. The
Download Tool shows the identification data of the present configuration and the
new configuration, and asks the user to verify, that the present configuration can be
overwritten before proceeding with the download.

Main configuration rules
6.1.
General
Make sure that all analog signals are connected and all necessary inputs and outputs
are wired. Note that the outputs of function blocks may not be connected together.
There are also many other FBD programming rules to follow. One of the most
typical rules is not to use the wired-OR connection. All signals that are connected to
the same output signal (both output relays and horizontal communication outputs)
must be connected via an OR gate (see Fig. 6.1.-1).

ORgate
Fig. 6.1.-1 Use of an explicit Boolean OR gate (on the right)
6.2.
Digital inputs and outputs
Digital inputs and outputs of RED 500 devices are implemented as directly
represented global variables. As such, they are special cases and their use in the
configuration is limited. Directly represented variables are declared in the Global
Variables sheet of the project tree. They can be recognized by the AT keyword as in
the examples below.
BIO1_5_BI1
AT %IX 1.8.2
:BOOL := FALSE;
( *Binary input X5.1/1,2 *)
BIO2_7_PO1
AT %QX 1.13.2
:BOOL := FALSE;
( *Single pole output X7.1/17,18 *)
Note that the parts of the line following the AT keyword may not be changed. Only
the name of the signal, that is, the part before the AT keyword, may be changed if
required.
If the names are adapted to the logical meanings of the signals, the user is
encouraged to create and to follow a naming convention. The name should indicate,
apart from the logical meaning, whether the signal is an input or output signal.
Examples of such names following a naming convention could be:
Q9_close_sta_IN
AT %IX 1.8.2
:BOOL := FALSE;
(* Binary input X5.1/1,2 *)
Q9_close_cmd_OUT
AT %QX 1.13.2
:BOOL := FALSE;
(* Single pole output X7.1/17,18 *)
Access direction for the directly represented variables is restricted by their purpose.
This means that a digital input can be read but not written, see Fig. 6.2.-1 below.
Accordingly, an output can be written but not read. Note that an input can be read
from several locations within a worksheet and even from any program organisation
unit within the configuration, whereas an output can only be written from one
location at a time.

6.3.
Explicit feedback path
A feedback path exists on the FBD worksheet when an output of a function block is
used as an input to a function block that precedes it in the execution order. There are
two types of feedback paths, an explicit and an implicit feedback loop (see Fig. 6.3.1 and Fig. 6.3.-2 below). It is strongly recommended that explicit feedback loops are
changed to implicit loops by using a feedback variable.
The Relay Configuration Tool can detect explicit loops during compilation. If you
click the checked command Display warnings in the Make menu, the compiler
gives warnings about the detected explicit feedback loops. To view the feedback
loops, select the checked command Highlight feedback in the Layout menu. The
execution order of functions compared to the expected behaviour may in some cases
dictate where the feedback variable should be added (for instructions on how to view
the execution order, refer to Section 6.7. Execution order). The initial value of the
feedback variable should also be selected with care.

6.4.
Analog inputs
Analog channels defined in the resource can be connected to the analog inputs of
application function blocks on a code body worksheet. Most of the function blocks
with several analog inputs support unconnected inputs. For example, in Fig. 6.4.-1
below, the function block NOC3Low operates on only two inputs. The third and
unused input constantly measures a zero current amplitude. This function block only
requires that at least one of the three inputs is connected.
On the other hand, certain function blocks require that all analog inputs are
connected. An example of such a function block is OV3Low (see Fig. 6.4.-1 below).
If the analog channel requirements of a function block are violated, a configuration
error is generated. For more information on how analog inputs are expected to be
connected, refer to the function block manuals on the CD-ROM Technical
Descriptions of Functions, see Section 1.8. Related documents.
65
REF 54_, REM 54_, Protection & Control Terminals
RET 54_, REC 523
1MRS750745-MUM
Configuration Guideline
Analog channels connected to application function blocks may not be changed
runtime. Therefore, do not use any selectors between analog channels and function
blocks.
analog_inputs3
Fig. 6.4.-1 Connecting analog inputs of application function blocks. Do not use a
selector to switch between channels.
6.5.
Error outputs of application function blocks
If a configuration for a function block is not correct, its ERR output is activated
immediately after configuration downloading and the function block is forced to the
Not in use mode. In this case, application function blocks that have the Operation
mode parameter in their actual setting menu display the Not in use operation mode,
regardless of which mode has been selected for the parameter in the setting group
menu. Currently, with most function blocks, this will result in an automatic
resetting, without storing, of the relay. The automatic reset does not occur in
REM 54_.
The error signals of all application function blocks should be collected together via
an OR gate and connected to, for example, an HMI alarm indication of REF 54_ or
REM 54_, that is, an MMIALAR_ function block.
Detecting any untreated configuration errors is fast and easy when
the error signals of all application function blocks are collected
together via an OR gate and connected to MMIALAR_ function
block.
Configuration errors typically originate from missing special measurements, the
type, order or number of analog channels connected to function blocks, or task
interval requirements.

Warnings
In case of the indication
Warning: Instance “xx” is never used
in connection with compilation, remove the corresponding instances
of the function block from the variables worksheet of the POU. The
tool does not give a warning for unused variables, which is why they
are recommended to be removed manually.
When a global variable is added to a sheet as a copy-paste -function,
the Global option button has to be chosen (see figure below properties can be accessed by double-clicking the right mouse
button); otherwise the variable becomes a local variable of the POU,
which is due to the auto-insert feature of the tool (global variable =
VAR_EXTERNAL, local variable = VAR).

Execution order
After compilation, check the execution order in relation to the calling sequence of
POUs by using the Layout Execution Order function. Note, however, that although
the connection of simple variables to each other generates code, the execution order
cannot be seen by means of the Layout Execution Order function. If the MOVE
function is used instead of direct connection, the execution order can be utilised in
concluding whether the result is desirable, for example, the reading and writing
order of the variables.

Engineering tips
7.1.
Horizontal communication
This example includes four (4) bays. The logic is basically the same in every bay.
The intention of this guideline is to point out how to ensure the horizontal inter-bay
communication, including correct state indication of control objects via LON
communication. The logic also includes an alarm function in case of a broken fibre
optic. Incorrect updating of interlocking information blocks the control of objects,
but the blocking can be bypassed by setting the device to the bypass mode.
7.1.1.
Guideline for using LON NV-variables in PLC logic
Communication between terminals is executed by using the communication input
and output signals (global variables COMM_IN_ and COMM_OUT_). The logic
must be designed in a Relay Configuration Tool project. The LON network variable
bindings can be created with the LON Network Tool.
Communication inputs and outputs are bound to each other on a one-to-one basis by
means of unacknowledged repeated unicast service. The signals are named so that
the number at the end of COMM_OUT_ (for example COMM_OUT2) denotes the
bay to which the signal is sent. Accordingly, the number at the end of COMM_IN_
denotes the bay from which the signal is received. This way, COMM_OUT2 of bay
1 is bound to COMM_IN1 of bay 2.

COMM_IN
COMM_IN_ signals are converted into Boolean logic mode by INT2BOOL
function blocks. The B0 output signal (BLOCK1) in an INT2BOOL function block
is used for blocking the control of objects except for the one that is sending the
signal. In other words, only one object can be controlled at a time. Furthermore,
Comm-Check_ signals are used for checking the condition of fibre optics. Signals
for bay interlocking are also received. See Fig. 7.1.1.1.-1.

COMM_OUT
Communication signals sent from one bay to other bays include the reservation of
control objects, updating of communication output signals and some indications
needed in other bays. Overall, digital signals are sent via LON and converted from
Boolean logic to unsigned integer (UINT, 16 bits) values.

Cyclic sending generation
The logic below shows an example of how the cyclic sending of communication
output signals can be generated. The idea is to generate a boolean signal with a
5-second pulse duration and a 50-percent duty cycle.

Cyclic communication check
Timers check the horizontal communication The timers activate an alarm signal as
a result of failed communication (Bay__Comm_Failed) 15 seconds after the new
value of a Comm-Check_ signal has been received. Comm_Check_ signals are
updated every 5 seconds, which affects the TON timer functions thus preventing the
activation of Q output signals. If the communication fails, all four bays are blocked.

7.1.1.5.
Blocking
If horizontal communication has failed, the BLOCK2 signal is sent to every
controllable function block to prevent the control of local objects. Furthermore, the
HMI alarm indication 8 (in REF 54_ , REM 54_ or RET 54_) is activated.
The BLOCK1 signal is used to create a mutual exclusion effect between bays. The
signal is activated by horizontal communication when a control object is selected in
one of the other bays.

BLOCK
Fig. 7.1.1.5.-1 Blocking the control of objects
7.1.1.6.
Control of objects
The control of an object, for example a breaker, can be executed if the BLOCK input
is not active (TRUE). Accordingly, an object cannot be controlled during the
reservation of other objects (in the same bay or in other bays) or the failing of
horizontal communication.
However, the blocking can be bypassed by setting the terminal to the bypass mode
(MAIN MENU/Control/General/Interlocking Bypass). The bypass
mode overrides interlockings provided the bypass signal is included in the logic (see
also Section 7.1.1.7. Bypass mode).

Bypass mode
The bypass mode signal can be generated in the logic via the COLOCAT function
block. After activation of the bypass mode, the BYPASS signal is active and
therefore prevents activation of the BLOCK input.

7.2.
Events from the measurement function blocks
SPA protocol used
Measurement values have to be polled because they are not sent with events.
Thereby the delta supervision events of the measurement function blocks can be
masked off.
If limit supervision is set to be done by RTU, the limit event sending must be
allowed in event masks. In this case, the client is informed of the activation and
resetting of each limit with the corresponding event code numbers.
LON protocol used
Each measured variable is individualized by an IEC address. Measurement values
and the corresponding IEC addresses are sent to a client, for example to
MicroSCADA, with both delta supervision events and limit supervision events.
The limit supervision events are not recommended to be masked off if
limit supervision is used.
When the warning and alarm limit supervision is active, the priority for limit event
sending is higher than that for delta event sending if both type of events are sent
concurrently. Concurrent event sending appears, for example, when a measured
value changes considerably during a short period, for example when a circuit
breaker is closed or opened. This causes problems if limit supervision events have
been masked off since the client does not receive all measurement values even if
major changes have taken place.

Functionality logic
Please specify the required special PLC logic functionality (see the examples
below), by drawing or otherwise, on separate sheets and enclose all additional
information with this document (Specification for Feeder Terminal Configuration).
Example 1: Earthing sequence
Earthing of the outgoing feeder can be done by a circuit breaker when an earthing
sequence is activated, an earthing switch is earthed and no voltage is measured. If
all conditions are fulfilled, the circuit breaker can be closed after 1 second. The
figure below shows the implementation of the desired logic.

Functionality logic
Please specify the required special PLC logic functionality (see the examples
below), by drawing or otherwise, on separate sheets and enclose all additional
information with this document (Specification for Machine Terminal
Configuration).
Example 1: Earthing sequence
Earthing of the outgoing feeder can be done by a circuit breaker when an earthing
sequence is activated, an earthing switch is earthed and no voltage is measured. If
all conditions are fulfilled, the circuit breaker can be closed after 1 second. The
figure below shows the implementation of the desired logic.

Functionality logic
Please specify the required special PLC logic functionality (see the examples
below), by drawing or otherwise, on separate sheets and enclose all additional
information with this document (Specification for Transformer Terminal
Configuration).
Example 1: Earthing sequence
Earthing of the outgoing feeder can be done by a circuit breaker when an earthing
sequence is activated, an earthing switch is earthed and no voltage is measured. If
all conditions are fulfilled, the circuit breaker can be closed after 1 second. The
figure below shows the implementation of the desired logic.

APPENDIX F: Power quality application guide
for harmonics
13.1.
Power quality and harmonics
Power quality is a topic that defines the limits for delivered electricity in power
network. The key issue is to define acceptable variation limits to ensure that endcustomers are able to utilise the delivered power. Power quality is ultimately a
customer-driven issue.
Excellent power without interruptions is the ultimate target. Today this target has not
been reached. There are many kind of disturbances in the network affecting power
quality. Interruptions and other disturbances weaken the utilisation of delivered
power in end-customer facilities. If these disturbances have noticeable effects on the
utilisation of power, disturbances should be blocked out or the system should be
made immune to these disturbances. Before taking action to reduce the effects of
disturbances, the reason and source of the disturbance should be found. Only after
that can reasonable solutions be weighted against costs and benefits.
Harmonics, that is, distortion in the voltage and current waveforms, are one of the
factors affecting power quality. Harmonic distortion is caused by non-linear loads
that are, for example, electronic power supplies, converters, arc furnaces and arc
welders. Harmonics may cause maloperation of devices, additional heating in
devices and telecommunication interference. The importance of harmonics is
emphasized by the fact that the amount of equipment generating harmonics
constantly increases. Still, it should be noticed that the existence of harmonics is not
automatically a problem.
13.2.
Background for harmonics
A periodic distorted waveform can be expressed as a sum of sinusoids. The
waveform can be represented as a sum of pure sine waves in which the frequency of
each sinusoid is an integer multiple of the fundamental frequency. This multiple h is
called a harmonic of the fundamental. Harmonics added to the fundamental
frequency can be odd harmonics (the integer multiple h is 3,5,7...) or even harmonics
(where h is 2,4,6...). In Fig. 13.2.-1 odd harmonics with the amplitude 0.1 p.u. of the
fundamental are added to the fundamental frequency.

Configuration Guideline
Voltage sources, that is, generation plants do not generally generate harmonics.
Harmonics are created because of power system non-linearity. Non-linear
components and loads cause distorted currents because of their operational
principles. Distorted currents flow through system impedance causing a voltage
drop for each harmonic. This results in voltage harmonics appearing at the load bus.
The created voltage distortion can be calculated if current harmonics as well as
system frequency response are known. In most cases the system frequency response
is very difficult to determine. Power system is a very large system that contains
many non-linear components. This makes it difficult to precisely predict the effects
of harmonics in different parts of the power system.
13.3.
Harmonic sources
The most important harmonic sources are basically converters and power supplies
for numerous electrical equipment. This equipment is a source for harmonics, and at
the same time, its operation principles may be very sensitive to harmonics,
especially to voltage harmonics. Still, some devices can be designed to decrease
their characteristic harmonics.
Single-phase power supplies
A major harmonic concern in commercial buildings is that power supplies for
single-phase electronic equipment will produce too much distortion for the wiring.
Direct current power for modern electronic and microprocessor-based office
equipment is commonly derived from single-phase full-wave diode bridge rectifiers.
Modern technology for single-phase power supplies is based on switch-mode. A
distinctive characteristic of switch-mode power supplies is the very high thirdharmonic content in the current. Other characteristic harmonics are the 5th and 7th
harmonics. Switch-mode power supplies are beginning to find applications in
fluorescent lighting systems. Typical current harmonics and the waveform for a
switch-mode power supply are shown in Fig. 13.3.1.-1.

13.3.2.
Three-phase power converters
Three-phase electronic power converters differ from single-phase converters mainly
because they do not generate the third harmonic or the third harmonic is quite small.
There are many designs and types of converters for AC or DC drives with different
power ratings. Harmonics may vary significantly between designs and operation
conditions. Still, some examples are given below.
Six-pulse and twelve-pulse converters
Harmonic components of the AC current waveform with q-pulse rectifier are:
h = kq ± 1
and the magnitudes of the harmonic currents are:
I1
I h = --h
where

The most significant harmonics for six-pulse converters are the 5th, 7th, 11th and
13th. For twelve-pulse converters, the 11th, 13th, 23rd and 25th harmonics are the
most significant.

This means that harmonics may vary significantly and interharmonics (non-integer
multiple of fundamental frequency) may also appear. Characteristic harmonics for a
six-pulse cycloconverter are harmonics from fundamental to 2nd, 5th to 7th, and
11th to 13th.
13.3.3.
Other harmonic sources
There are many other harmonic sources in addition to converters and power
supplies. These sources are mainly arching devices like arc furnaces and welding
equipment.
Arc furnaces
The harmonics produced by electric arc furnaces used for the production of steel are
unpredictable. The steel scrap to be molten is a very non-linear load and thus the
melting arc changes constantly. The arc current may be non-periodic and may
include both harmonics and interharmonics. Still, in most applications, the loworder harmonics starting with the second and ending with the seventh predominate
the non-integer harmonics. Fig. 13.3.3.-1 presents typical harmonics for an arc
furnace during the initial melting period and the refining period. These harmonics
have quite a low percentage magnitude compared to the fundamental component.
Arc furnaces form a large load with fundamental currents of several kA, which
makes arc furnaces a significant harmonic source for the power system.

Saturable devices
Equipment in this class includes transformers and other electromagnetic devices
with a steel core, including motors. Harmonics are generated due to the non-linear
magnetising characteristics of the steel. Harmonics are due to exciting current,
which is very rich in harmonics like the 3rd, 5th, 7th and 9th. Transformers are not
as much a concern as electronic power converters because exciting current is small
compared to the rated full load current. However, their effect will be noticeable
particularly on utility distribution systems that have hundreds of transformers. A
significant increase in triplen harmonic currents is often noticed during the early
morning hours when the load is low and thus the percentage of harmonics compared
to the fundamental is high.
Motors and synchronous generators also exhibit some distortion, although it is
generally of little consequence.
13.4.
System response characteristics
The effect of one or more harmonic sources on a power system will depend primarily
on the frequency response characteristics. The non-linear components described in
Section 13.3. Harmonic sources can be represented generally as current sources for
harmonics. Harmonic currents flow through impedance causing harmonic voltages.
Some basic rules for the harmonic current flow are given in this section.
Flow of harmonic currents
Harmonic currents tend to flow from the non-linear loads (harmonic sources)
towards the lowest impedance, usually the utility source. This was shown in
Fig. 13.2.-2. However, other connected loads provide an alternative path for
harmonic currents. The flow path to be chosen will depend on impedance ratios.
This may result in a situation where a neighbouring load includes harmonics
although there are no harmonic sources in this load branch. Harmonics generated by
other load branches will flow to this branch. This is shown in Fig. 13.4.-1.

Transformers
Transformers essentially isolate the load at higher harmonic frequencies. High-order
harmonics are not passed through transformers. Another effect of the transformers
is the isolation of triplen harmonics due to the transformer winding design. Triplen
harmonics tend to stay trapped into the delta connection and do not show up in the
line currents in the delta side. Some examples for the third harmonic current flow in
transformers are shown in Fig. 13.4.-2.
Harmtran.CNV
1MRS750745-MUM
Fig. 13.4.-2 Third harmonic flow in a wye-delta-connected transformer and in a
wye-wye-connected transformer
These rules about triplen harmonic current in transformers only apply to balanced
loading conditions. When the phases are not balanced, the triplen harmonics may as
well show up where they are not expected.
Fig. 13.4.-2 also shows the nature of the third harmonic and neutral line. Third
harmonics in line conductors tend to be in phase with each other. This means that as
currents summarise in neutral connection, the third harmonic in neutral line is three
times the third harmonic in the line conductor. This may result in a too high current
flowing in the neutral conductor.
Capacitors
Capacitor banks used for voltage control and power factor correction are the major
components that affect the system frequency response characteristics. Capacitors
can chance the system response to harmonics by creating high impedance or, on the
other hand, low impedance for harmonic currents at some frequencies. This means
that although capacitors are not harmonic sources, they may cause severe harmonic
distortion. On the other hand, capacitors can be used for creating paths with the
153

RET 54_, REC 523
1MRS750745-MUM
Configuration Guideline
lowest impedance for harmonics and applied to filtering of harmonics. The
connection of capacitors may cause resonance conditions that may magnify
harmonic levels.
13.5.
Effects of harmonics
The main effects of voltage and current harmonics within the power system are:
• Amplification of harmonic levels resulting from series and parallel resonance
• Reduction of efficiency in power generation, transmission and utilisation
• Ageing of the insulation of electrical plant components and thus shortening of
their useful life
• Equipment maloperation
Resonances and capacitors
The presence of capacitors may result in local resonances. Resonance conditions
may lead to excessive harmonic currents and voltages which increase heating and
voltage stress in capacitors. Another area where resonance effects may lead to
component failure is associated with the power line signalling (ripple control) for
load management. In such systems, tuned stoppers (filters) are often used to prevent
the signalling frequency from being absorbed in low impedance elements, such as
power factor correction capacitors. Where local resonance exists, excessive
harmonic currents can flow, resulting in damage to the tuning capacitors.
Rotating machines
A major effect of harmonic voltages and currents in rotating machinery (induction
and synchronous) is increased heating due to iron and copper losses. Harmonic
pairs, such as the fifth and seventh harmonics, have the potential for creating
mechanical oscillations in a turbine-generator or in a motor-load system. Then highstress mechanical forces may be developed. A pulsating output torque may affect the
product quality where motor loads are sensitive to torque variations.
Transformers
With the exception that harmonics applied to transformers may result in increased
audible noise, the effects of harmonics on these components usually arise from
additional heating. Current harmonics cause an increase in copper losses and stray
flux losses. Voltage harmonics cause an increase in iron losses and stress the
insulation. Additional heating may result in overheating with less than rated load.
Accelerated ageing of transformers is also possible.
Electronic equipment
Power electronic equipment is susceptible to misoperation caused by harmonic
distortion. This equipment is often dependent upon accurate determination of
voltage zero crossing or other aspects of voltage wave shape. Other types of
electronic equipment may be affected by the transmission of ac supply harmonics
through the equipment power supply or by the magnetic coupling of harmonics into
equipment components. Computers and allied equipment, such as programmable
controllers, may suffer from erratic data or malfunctions. Malfunctions may in some
154
1MRS750745-MUM
Protection & Control Terminals

RET 54_, REC 523
Configuration Guideline
cases have serious consequences, for example in medical equipment. Less dramatic
interference may occasionally be observed in radio and television equipment, as
well as in video recorders and audio reproduction systems.
Metering
Metering instruments initially calibrated on pure sinusoidal alternating current and
subsequently used on a distorted electricity supply may be prone to error. Both
positive and negative metering errors are possible because error is connected to the
direction of the harmonic flow. In general, the distortion must be severe (>20%)
before significant errors are detected.
Telephone interference
The presence of harmonic currents or voltages in circuitry associated with power
conversion apparatus may produce magnetic and electric fields that will impair the
satisfactory performance of the communication system that, by virtue of its
proximity and susceptibility, may be disturbed.
13.6.
Applications for harmonic measurements
Harmonics measurement function blocks can be utilised in applications like
monitoring power quality affected by harmonics, monitoring harmonics in selected
points of the network and locating sources of harmonics.
13.6.1.
Power quality and harmonics
There are several standards and recommendations for acceptable levels of
harmonics in power system. Recommendations for both voltage and current
harmonics can be found for distributed electricity. European Standard EN 50160 and
IEEE Std 1159-1995 are well known references for power quality.
Harmonic measurements can be utilised in several ways in the network. Here a
utility 110/20 kV substation is taken as an example. The substation is shown in
Fig. 13.6.1.-1 with measurement points for currents and voltages on 20 kV side.
There are three feeders connected to busbar. Feeders have different types of loads
connected. Load A is generating harmonic currents and load B is a simple motor or
resistive load. In addition, there is a capacitor unit connected to the busbar for
reactive power compensation. This unit could also include load.

feeders
Power quality affected by harmonics at the substation can be measured in the
incoming feeder for both voltage harmonics and current harmonics. If individual
feeders are monitored, it should be noticed that measuring the current harmonics
from each feeder is enough. The 20 kV bus voltage is common for all of the feeders.
Measuring the voltage harmonics from all the feeders results in unnecessary
information. Most of the time only the most important feeders (for example
harmonic sources) are monitored.
13.6.2.
Harmonic monitoring with individual loads and devices
Harmonic measurement function blocks can be applied to monitor harmonic levels
on different types of loads and devices. There are several standards for acceptable
harmonic levels with different devices. Recommendations are also given by
equipment manufacturers. Still, it should be noticed that “harmonic protection” with
PQVO3H and PQCU3H is not applicable. These function blocks have a long
measurement delay to update values (minimum 600 ms). Another feature is that all
kinds of spikes and other rapid changes in measured signals are filtered off from
output values. Measurement of interharmonics is not possible.
Some general recommendations for acceptable harmonic levels are the following:
1. Transformers
• Current distortion should not exceed 5 percent
2. Motors
• Heat problems begin when voltage distortion reaches approximately 8 percent
(motor unit without drive, harmonics in drive input may be considerably higher
as shown in Section 13.3. Harmonic sources)
156
1MRS750745-MUM
Protection & Control Terminals
REF 54_, REM 54_,
RET 54_, REC 523
Configuration Guideline
3. Capacitors
• Voltage limit to 120 percent of peak voltage (with harmonics) -> sum of
individual voltage harmonics <20% with rated fundamental
In case of feeders containing many individual loads and devices, it is difficult to
recommend levels according to specific devices. In such a case, the
recommendations given in standards for power quality can be followed. Then the
harmonics are monitored for the feeder itself, not for the load devices.
13.6.3.
Locating sources of harmonics
On radial utility distribution feeders and industrial plant power systems, the main
tendency is for harmonic currents to flow from the harmonic producing load (Load
A in Fig. 13.6.1.-1) to the power system source (towards 110 kV incoming). The
impedance of the power system is normally the lowest impedance seen by the
harmonic currents.
There are factors that may alter the path for at least one harmonic. These factors were
discussed in Section 13.3. Harmonic sources. Transformers may block some
harmonics, power factor correction capacitors may provide paths for higher-order
harmonics, and there may be harmonic filters.
To locate the harmonic source (Load A), harmonic currents in all feeders, including
the incoming feeder, should be measured. These results should be checked against
each other. The harmonic source is the one containing the largest amount of
harmonics. It may also be useful to check the harmonic flow while the power factor
capasitances are not connected. In this situation, paths for harmonics should be
decreased and locating the sources of harmonics should be easier.
13.6.4.
Harmonic filter performance monitoring
Harmonic filters are designed to catch harmonic currents produced by harmonic
sources. There can be filters for a single harmonic component or filter banks for
several harmonic components, like the 5th, 7th, 11th and 13th harmonics. The
current harmonic measurement function block can be utilised to evaluate how well
the harmonic components are caught into the filters. In case of a filter bank designed
to catch several harmonic components, the connection of the filter bank to the
system may lead to a situation where uncharacteristic (mostly even) harmonic
components are created. These uncharacteristic harmonics may have unwanted
effects on the system performance and the filter bank. Even though the level of
uncharacteristic harmonics is low and negligible after installation, the harmonic
levels may be considerably magnified due to the ageing of capacitors in the filter
bank.
