CYME 5.04 for Distribution, Industrial and Transmission Systems

With the numerous enhancements and additions to the software, this new version of CYME continues to deliver quality and cutting-edge solution for distribution, industrial and transmission system studies.

Growing alongside the Distributed Energy Resources (DER) developments, CYME continues to invest in its ability to address the needs of engineers who need tools to study various aspects of DER interconnection. New tools include:

Long-Term Dynamics Analysis

Single-phase DER short-circuit contribution

Anti-Islanding protection for inverter-based distributed generation (DG)

Analyses such as Load Flow, Optimal Capacitor Placement and Harmonics have been enhanced with new options. The new Fault Flow calculation engine is more robust and effective, while fully supporting complex phase merging configurations like most CYME analyses do. Optimal Power Flow (OPF) analysis, an advanced system planning tool, has also been added. An improved Advanced Project Management tool provides you a powerful tool to create scenarios, compare, correct and merge your study files in order to make your project planning hassle-free.

Equipment modeling capabilities have been extended with the addition of new equipments and enhancements of existing ones. Voltage regulator modeling now offers the by-phase type and recognizes the distinction of its construction type. Overhead line modeling has been revamped with detailed spacing modeling. New additions to the equipment library include busway, switchable shunt banks and more.

Distribution System AnalysisLong-Term Dynamics Analysis

The Long-Term Dynamics Analysis is a time-series simulation catered for the study of how DER impact network controls such as load tap changers and capacitors.

The variable DER output is affected by:

Insolation curves

Wind speed curves

Load and other generator profile curves

To properly simulate tap changing and capacitor switching, the analysis also takes into account:

Regulators tap changer delay, mechanism delay, timer reset modes

Capacitors close delay, trip delay, breaker delay

Full Phase-Merging Capability

The analytical capability of more CYME analyses have been extended to fully support phase-merging, including bidirectional flow sections.

Load flow

Short Circuit

Fault Flow

Load Allocation

Long-Term Dynamics

Capacitor placement

Load Balancing

Transmission and Industrial System AnalysisSmart Grid Solution with Optimal Power Flow

CYMEs Optimal Power Flow (OPF) analysis is an advanced system planning tool which automatically finds optimal device settings to satisfy selected objectives within specific constraints. It is a powerful solution for system performance optimization and cost-efficiency improvement.

A choice of 11 different objectives is offered, and they can be used individually or simultaneously. Among these objectives are:

Minimize reactive power losses

Minimize load shedding

Maximize flat voltage profile

Minimize fuel cost

Controllable system variables include generator power settings, transformer tap settings, load participating in load shedding and switchable reactive bank control.

Infeasibility handling and constraints relaxation offer greater flexibility in system convergence and OPF will always provide you with a solution for better system asset management.

Transmission Line Models

Tower Configurations have been added to CYME 5.04.

Double-circuit configurations and single circuit configurations are now available, making the modeling of a variety of tower configurations possible.

FACTS Devices

To complement the implementation of transmission line models, FACTS devices have been added. These devices are:

STATCOM

UPFC

DC Links

CYME 5.04 has also incorporated the design of HVDC links.

Detailed rectifier and inverter transformer modeling

Harmonic spectrum according to rectifier and inverter parameters

Switchable Shunt Banks

This new device would allow a group of capacitor banks or reactor banks to be switched on/off to control the voltage at a given bus.

Harmonic Line Models

The Harmonic Analysis has been enhanced to include new line models such as:

Distributed transposed, with skin effect

Distributed transposed, frequency-dependent

Distributed untransposed

Transmission and Industrial System AnalysisVariable Frequency Drive

The variable frequency drive (VFD) can now be represented as separate equipment with its own database and network settings. The VFD can now be connected to an induction motor with a secondary cable and offers speed control for motor starting analysis purposes.

Depending on the operating frequency, the VFD can either be in constant current or in constant power operating mode.

New Equipments

New equipments added to this version include:

Busway

Phase-shifting transformer

Reactive power flow control transformer

Impedance relay

Frequency droop relay

Motor different RPM mode

The Gear Ratio is now an available option to represent the case when the load RPM is different than the motor synchronous speed.

Series Fault and Simultaneous Fault Analyses

Two new fault analyzes have been added to CYME 5.04:

Series faults conditions of one-phase open, two-phase open or three-phase series unbalance conditions

Simultaneous faults which could be a shunt fault at more than one location or a combination of shunt and series faults.

Anti-Islanding Protection

This is implemented for electronically coupled DG:

Photovoltaic (PV)

Wind turbines

Micro turbines

Solid oxide fuel cells

These controls are activated when islanding is detected under transient conditions to disconnect any DG when certain voltage and frequency criteria are met.
