Capacitor Bank shall be provided by a microprocessor-based package. The
microprocessor-based package shall be suitable for Pole Top Mounted or Pad
Mounted Capacitor Banks, as well as Single-Stage Substation Capacitor Banks
operating in Non-Series configurations. The control shall have the following
minimum functional and behavioral attributes:
CONTROL FUNCTIONS
The capacitor bank control shall include the following features and can be used for pole-mounted
or pad-mounted capacitor banks as well as non-series, single-stage, substation banks where
SCADA communications are desired.
LOCAL AUTOMATIC CONTROL MODE:
The Control shall have the following selectable Local Automatic Capacitor Control
Methods: Classic Voltage, Adaptive Voltage, VAr, and Current with settings appropriate
to the method selected.
Capacitor Control Local Automatic Overrides: Maximum / Minimum Voltage Limits,
Temperature, Time.
CLOSE and OPEN timers shall be provided with selectable Definite or Inverse Time
Delays and Instantaneous or Integrating Reset Characteristics.
Timer Types: Selectable as Integrating or Instant Reset
CLOSE and OPEN Output Pulse Duration adjustments shall be provided.
CLOSE and OPEN Warning Delays shall be provided.
A mandatory Re-Close Delay shall be provided to permit capacitors to discharge before
re-closing after a prior trip.
A minimum time-between-operations timer shall be provided that begins timing when any
operation completes and prevents the OPEN or CLOSE timer from beginning operation
due to an out-of band condition until the timer’s setting is reached.

CAPACITOR BANK CONTROL OPERATION:
Control Operating Characteristic: The capacitor bank control operating characteristic shall be
configurable for voltage, VArs, or current. The control’s configurable operating characteristic shall
employ definite as well as inverse timing and provide an adjustable bandwidth to optimize bank
operation and eliminate unnecessary switching. The configurable operating characteristic shall
allow time and/or temperature overrides.
The voltage control mode shall include two standard modes of automatic operation:
Classic voltage control shall make its Open and Close switching decisions based on
measured Line Voltage conditions and Time and/or Temperature overrides when applied.
Voltage excursions beyond the set value for greater duration than the time-delay will
result in appropriate control operation.
Adaptive voltage control contains two control methods, Fixed or Average. The Fixed
method provides a bandcenter setting the control uses for comparison to measured
voltage to make its open or close capacitor bank switching decisions. The Average
method uses an Effective Bandcenter based on a long-term average of the input voltage
to compare to measure voltage to open or close the capacitor bank. Both methods
employ an inverse timer and bandwidth to optimize bank operation, eliminating
unnecessary switching, and allow application of Time and/or Temperature overrides.
SCADA REMOTE MANUAL CONTROL MODE:
SCADA Remote Manual Mode: Remote Manual Mode may be used by the IVVC algorithm
residing at the Master Control Center of the SCADA computer or other Host computer. The
control shall be capable of operating from SCADA signals received through wired or wireless
communications media to command bank switches for OPEN and CLOSE operations. The cap
bank control shall maintain an Overvoltage and Undervoltage Limit supervision to protect the
“never to exceed” voltages set as standard by the local Public Utilities Commission and SCADA
shall be allowed to make OPEN and CLOSE commands as necessary when operating within
those safety limits. The cap bank control shall provide a means to switch from Remote Mode to
Automatic Mode if communications fail and continue to operate autonomously until
communications are restored. The control shall provide contingency responses upon extended
loss of communications.
The capacitor bank control shall utilize a SCADA integrity monitor (SCADA Heartbeat) as well as
additional means to monitor the on board communications module for loss of its own operation.
Either failure or loss of communications from master or from slave shall trigger the cap bank to
switch to Automatic operation. After communications are restored for a specified length of time,
the cap bank control shall revert to SCADA Remote Manual Control Mode. This may be done
automatically after a time-delay or as directed by SCADA Master.
SCADA Remote Manual Mode - SCADA Heartbeat: A SCADA Heartbeat Remote Mode shall
be provided as a means for the SCADA system to place the unit in Remote Operation and
perform Raise and Lower operations as directed by a central control source. This mode shall
have a timer, and as long as the Remote Timer setting in the control is refreshed by the SCADA
system receiving a valid DNP 3.0 command, and before timing out, the control shall remain in
Remote Manual Operation. If the delay times out, the control shall revert to Local Automatic
Operation. The Local Automatic Operation shall switch back to Remote Manual Operation upon
receipt of a valid DNP 3.0 command via SCADA.

SCADA REMOTE MANAGEMENT OF LOCAL AUTOMATIC CONTROL MODE:
SCADA Remote Management of Local Automatic Control Mode: The capacitor bank control
shall have the capability to allow Remote SCADA Management of Local Automatic Capacitor
Control. In this way, the Centralized Control can monitor cap bank controls allowing them to
operate autonomously and only controlling them directly when emergency situations arise.
Management via SCADA or other Host computer capable of operating through wired or wireless
communications media allows SCADA to effect control by either changing the local automatic
control settings via analog signal or, by sending binary commands for direct OPEN and CLOSE
operations. Sending analog settings to the control and letting it operate based on its new
marching orders instead of directing each open and close or raise and lower commands
considerably conserves bandwidth and thereby minimizes the communications burden and total
cost of operation.
The control shall provide a SCADA Test Mode that blocks the unit’s physical outputs, removes
the Re-Close delay, and prevents a Close operation for a minimum of five minutes after an
OPEN. The control LEDs, front panel, and remote status indications shall still indicate bank
operations as if the outputs were not blocked to allow user verification of settings, correct SCADA
communications point mapping, and operation.
The control shall provide a Re-Close Delay override to allow a CLOSE operation after an OPEN
operation without time-delay. This feature is used only when the bank switches are physically
disconnected from the capacitor banks to allow lab- and field-testing of the unit’s wiring and
switches.
INSTALLATION CONFIGURATION SETTINGS:
VT Ratio Correction: The control shall provide VT ratio correction.
Phase Shift Compensation: The control shall provide phase shift compensation correction when
in VAr or Current Control mode to correct for phase shifts normally encountered in line post
sensors, and when current information sources are located on phases other than the measured
voltage source.
Operations Counter: The control shall provide a software counter that increments by one count
per either a CLOSE or an OPEN operation.
Re-settable Operations Counter: The control shall provide a second software counter similar to
the operations counter that may be reset by the user.
COMMUNICATIONS
The communication ports shall provide access to all features, including metering, software
updates, and programming of all functions. This shall be accomplished using a modem or direct
serial connection from any PC-compatible personal computer running the control’s
Communications Software package or via SCADA communications software.
Communications Ports: Communication ports shall be optionally available in the following
forms:
 Ethernet 10/100 Mbps through a copper RJ-45 connection (100 Base-T)
 Ethernet 100Mbps Fiber Optic with ST connectors (100 Base-FX)
 Serial Ports with RS-485, ST or V-Pin Fiber Optics, or RS-232
Page 3 of 10
File: M-6280A-Sugg-Spec.doc
Protocols: The control shall support the following standard protocols: DNP3.0 and MODBUS.
The USB port shall utilize MODBUS for local interface communications. The Ethernet port
supports DNP 3.0, MODBUS, and IEC 61850 protocols over TCP/IP.
Advanced SCADA Communications:
True Ethernet
The control shall provide an integrated, true 10/100 Mbps Ethernet, auto negotiable, capable of
supporting up to eight concurrent sessions and simultaneous multiple protocols with up to eight
sockets (concurrent sessions) open at a time. The eight sockets shall be capable of supporting
Modbus and DNP over TCP/IP and up to five of the eight sockets shall be capable of supporting
DNP 3.0. This requirement allows users simultaneous remote access to the control via the same
physical Ethernet port to view/change settings or retrieve data, without affecting the SCADA
communications.
The control shall provide full DNP implementation to support both report-by-exception and
unsolicited reporting within DNP 3.0 to aid in the reduction of bandwidth requirements. The
control shall also provide DNP File Transfer to permit the recovery of data logs and triggered
events, oscillography, and device discovery to facilitate setting up the integrated system.
Full DNP Implementation
The control shall provide full DNP implementation to support both report-by-exception and
unsolicited reporting within DNP 3.0 to aid in the reduction of bandwidth requirements. The
control shall also provide DNP File Transfer to permit the recovery of data logs and triggered
events, oscillography, and device discovery to facilitate setting up the integrated system.
The control shall have DNP addressing capability that allows networking of multiple controls. The
DNP implementation shall support the pre-defined global addresses within DNP 3.0 and allow the
user to define two additional global addresses. Each control shall be able to be assigned a
Device Address, Feeder Address, and Substation Address ranging from 1 to 65519. The control
shall support broadcast commands from the master to all controls on the network in order to allow
some or all controls to act on one command at the same time. This capability reduces bandwidth
and is critical for rapid response to changing system requirements with settings changes in
multiple controls in selected zones. The control shall provide a configuration program that allows
any point to be mapped into any DNP location and allows dummy filler points to be added to
facilitate interoperability by replicating legacy vendor point-maps to SCADA. This program shall
also allow for individual point dead-banding and individual point assignments into Class 1, 2, or 3.
Cyber Security
Within DNP, the control shall permit multiple master source-address authentications, sourceaddress validation, and multilevel access codes logged with date and time, with DNP
authentication using FIPS 180-2 Secure Hash Standard (SHA-1). The control shall be fully
compliant and offer all settings and configuration as defined by the DNP3 user group and IEC
62351-5. The control shall have a 6-15 character password and an audit log that shows when
someone is logged on the control and which password was used to gain access to the control, in
compliance with NERC CIP standards. The control shall allow for storage of 30 unique passwords
within each control and have an SD card slot to allow the use of a password-keyed SD card that
the control automatically reads to allow user login.
The control’s design shall include the ability to disable ports and services not required for normal
or emergency operations. In cases where disabling is not possible, the port or service shall be
password and access level protected through a communication access security and timeout
feature in the communication software.
Page 4 of 10
File: M-6280A-Sugg-Spec.doc
The control enclosure shall have a door contact for intrusion detection (part of NERC CIP security
requirements) wired into a digital input to alarm SCADA when someone opens the door of the
control. This alarm triggers a SCADA signal to block the address temporarily.
Bluetooth®
The control shall have an option for Bluetooth® capability to enable wireless access to the control
that allows the user to configure the control, read status and metering values, as well as change
set points. A generic serial service shall be provided by the control’s Bluetooth® capability to
facilitate establishing initial communications should the Bluetooth® not automatically recognize
listed services.
MONITORING
Harmonic Analysis: The control shall measure, log, and display individual harmonics including
THD (total harmonics distortion) of the load voltage and load current up to the 31st harmonic.
The control shall include a trip and lockout function that operates when Voltage or Current THD
increases above its associated THD Trip Pickup Setting for the period of the THD Trip TimeDelay setting. If THD is still present and rising above the THD Trip Pickup Setting after the trip
occurs, the lockout will remain in effect until THD decreases below a Voltage or Current THD
Lockout Reset setting for the duration of the THD Lockout Reset-Delay setting. This indicates that
the capacitor bank was resonating as part of the system L/C circuit and has the potential, if it
resonates for a long enough time, to explode
If the Voltage or Current THD levels that caused the trip drop immediately (within 1 second)
below the THD Trip Pickup Setting when the bank trips, then the Lockout shall remain in effect
only for the duration of a THD Lockout Reset-Delay setting. This case indicates that the capacitor
bank was actually part of the L/C system circuit and functioning as the filter, partially sinking the
harmonics.
The control shall have an internal counter that increments each time the following sequence
occurs:
1. A Voltage or Current THD Measurement exceeds its associated THD Trip pickup setting
for the duration of the THD Trip Time-Delay
2. The control trips the bank and locks out
3. The Voltage or Current THD measurement drops below the THD Lockout Reset Setting
as soon as the Trip occurs (within one second)
4. The THD Lockout Reset-Delay times out and the Lockout resets
The control’s design shall have a Maximum THD Lockout/Reset Operations setting that
determines the maximum number of Trip and Lockout/Reset Operations allowed within a period
of time specified by a Maximum Time for THD Lockout/Reset Operations before the control will
permanently lockout and require a user reset, either locally or remotely, to continue operation.
Settings Profiles and Triggers – the control shall provide up to eight settings profiles
programmable in the control that can be initiated based on Time, Temperature, Loss of
Communications, Reverse Power, or from SCADA. This feature shall allow the user the flexibility
to customize the operation of the control based on many different operational factors while
minimizing communications bandwidth. It shall also assist in maintaining local intelligence at the
device level in the event of either a loss of communications or with systems designed to operate
without communications.
