CYME 7.1 – New Features
Address the emerging Distribution, Industrial
and Transmission challenges with CYME 7.1
Eaton’s Cooper Power
Systems is proud to
announce the release of
its latest CYME 7.1 Power
Engineering Software.
CYME 7.1 takes a
significant step to redefine
the term “ease-of-use”
bringing both simplicity
and accurate results to
your fingertips. As part of
the CYME 7 Series, this
new version reiterates our
commitment to constantly
improve our software by
offering a unique solution
that combines a design
centered on the needs of
the power engineers and
leading-edge engineering
software tools.
CYME 7.1 is a version with a
range of enhanced capabilities,
featuring new modules, new
functionalities and extended
configuration options.
Key new features of CYME 7.1
include:
•
Optimal Recloser Placement
•
Optimal Voltage Regulator
Placement
•
DC Arc Flash Hazards Analysis
•
Online Maps Service
The Fuse, LVCB and Breaker
libraries have been re-designed
and enhanced to include
additional information such as
the standard ANSI/IEC data,
the voltage classification and
the frame size. The interrupting
ratings of all devices have also
been completely updated.
This new version also provides
easier navigation through
the one-line diagram. Several
improvements have been made
to the software’s Explorer Bar
where many tabs have been
re-designed for greater flexibility.
Quick access to the Network
Inventory and the Equipment
Inventory is provided, all from
the same tab. User-friendly
options such as resizing
columns, customized sorting,
customized grouping, conditional
formatting, mass modifying and
outputting to Microsoft Excel®
have been added to applicable
tabs.
Several enhancements have
been made to the equipment
dialog boxes in order to facilitate
the search and the grouping of
devices using keywords. The
user also has the possibility
to view only the items and
categories needed and hide the
rest of the equipment in the
library which makes it easy to
select an item for use in the
network.
The combination of
new analyses, userdriven functionalities and
improvements makes CYME 7.1
an essential for all your power
engineering studies.
Optimal Recloser Placement
Analysis
Optimal Voltage Regulator
Placement Analysis
Installing reclosers in optimal
locations to improve reliability
can be challenging. The new
CYME 7.1 Optimal Recloser
Placement analysis module
determines the optimal location
of the network to install the
reclosers. The assessment
is based on reliability indices
calculated from the Reliability
Assessment module.
The new CYME Optimal Voltage
Regulator Placement analysis
module recommends optimal
locations for voltage regulators
on a distribution network with
one or multiple feeders.
The analysis uses one or the
combination of the following
objectives based on the weight
of their importance:
•
Improve SAIDI (System
Average Interruption Duration
Index)
Optimization is achieved using
one or a combination of the
following objectives:
•
Flatten voltage profile at
specified target voltage
•
Minimize active power losses
With the Optimal Voltage
Regulator Placement module
one can:
DC Arc Flash Hazards Analysis

fields for construction details.
To complete the enhancement,
the section properties dialog
boxes of CYME 7.1 have been
redesigned to allow the detailed
modeling of any cable in your
networks.
Two new libraries complement
the Cable Equipment Library.
The Conductor Material Library
contains the electrical resistivity
and temperature coefficient of
various conductor materials.

the dielectric constant and
temperature limits of various
insulation materials. Additional
user-defined conductor and
insulation materials can also be
specified.

Distribution, Industrial and
Transmission challenges
with CYME 7.1.
Batch Analysis
Run several user-defined
scenarios on a selection of
studies, self-contained files

study parameters for each
simulation.
For one execution of the Batch
Analysis you can generate
detailed reports and summary
reports for multiple analyses.
To maximize your results, the
Batch Analysis can also be
coupled with the Advanced
Project Manager module and the
Automated Network Forecast
Analysis module to run the
Batch Analysis Scenario on userdefined project scenarios or subprojects.

Low-Voltage Distribution
Network Modeling and
Analysis
With CYME 7.1, the Low-Voltage
Distribution Network Modeling
and Analysis module is even
more powerful and complete
with the addition of new device
models for:
•
Center-tap connected sources
•
Center-tap connected meters
This allows you to specify a
center-tap demand. A precise
load allocation analysis is now
possible on a low voltage
network given the center-tap
demand.
Harmonic Analysis
New features in the Harmonic
Analysis module include:
•
An option within the source
model to add user-defined
background harmonic voltage
to the source harmonic
envelope.
•
Two new harmonic load
models Parallel R-L (with skin
effect) and Series R-L (without
skin effect).
•
A new filter sizing report
which provides harmonic
and fundamental resistor
losses, fundamental and
harmonic current through the
reactance and fundamental
and harmonic voltages across
the capacitor to help you size
your filter.
•
The addition of transformer
K-Factor (ANSI/IEEE) and
Factor-K (BSI) calculation to
the harmonic analysis. These
factors are necessary to
evaluate the nominal rating
of transformers serving
non-linear loads. Increasing
harmonic load currents have
a direct effect on transformer
overheating and transformer
losses (Eddy losses). The
higher the K-Factor/Factor-K
the greater the harmonic
heating effects. Two methods
are used:
• ANSI/IEEE C57.110™
where the K-Factor can be
used to select the proper
transformer (K-Factor of
1, 4, 9, 13, 20, 30, 40 or
50) without de-rating the
nominal rating.
• European Standard EN
50464-3:2007 where the
Factor-K represents a
transformer de-rating factor
to prevent overloads due to
non-linear loads.
Detailed center tap connected
load connections for spot and
distributed loads can now be
specified:
•
Phase (1-N)
•
Phase (2-N)
•
Phase (1-2)
Secondary Grid Network
Analysis
A new robust load flow method
tailored to solve heavily meshed
unbalanced secondary grid
networks is now available in the
load flow analysis dialog box.
You can now select the NewtonRaphson Unbalanced calculation
to perform a load flow on your
secondary grid network.
