BRIEF DESCRIPTION OF MODULES INCLUDED IN ACADEMIC VERSION
1. NETWORK EDITOR:
CYME power engineering software features an enhanced graphical user interface that provides the user with great flexibility in creating
the one-line diagram of the network as well as providing a wide variety of options to customize the displays and reports.
2. LOAD FLOW ANALYSIS:
CYMFLOW is the power flow analysis module of the CYME power engineering software for the analysis of three-phase electric power networks.
It is equipped with powerful analytical options and alternative solution techniques.
The objective of a power flow program is to analyze the steady-state performance of the power system under various operating conditions.
CYMFLOW utilizes state-of-the-art sparse matrix/vector methods and multiple solution algorithms: Full Newton Raphson, Fast Decoupled &
Gauss-Seidal.
3. SHORT CIRCUIT ANALYSIS (ANSI, IEC & CONVENTIONAL):
The CYME power engineering software features CYMFAULT, a short circuit analysis module dedicated to calculating shortcircuit currents
in three-phase electric power systems.
CYMFAULT adheres to International IEC-60909© guidelines and North American ANSI® C37.5, ANSI® C37.010, ANSI® C37.13 standards.
It also supports conventional short-circuit studies without reference to any particular standards.
4. TRANSIENT STABILITY (SINGLE MACHINE & MULTI MACHINES):
CYMSTAB is the transient stability module of the CYME power engineering software dedicated to simulating electromechanical transients
in balanced and unbalanced electrical power systems.
CYMSTAB utilizes the simultaneous implicit trapezoidal integration solution technique for network, machine and controller equations.
The program supports the capability to test the step response of controllers and user defined modeling for system equipment and controllers.
5. VOLTAGE STABILITY ANALYSIS:
CYMVSTAB is the analysis module is dedicated for the voltage security assessment of power systems. In planning and operating today’s
stressed power systems, the ability to maintain voltage stability has become a growing concern. CYMVSTAB is designed to meet this challenge
by assessing the ability of the power system to maintain stable voltages under different contingencies and loading conditions.
Power system voltage instability is related to the lack of reactive power resources in the network. This is very similar to frequency instability
in transient stability studies for systems that do not have sufficient spinning reserve.
6. AC CONTINGENCY ANALYSIS:
The AC CONTINGENCY operates in conjunction with CYMFLOW for Power-Flow related contingency analysis.
The contingency module is structured so that an unlimited number of “what-if” scenarios can be included in a given contingency study.
E.g. modification of loads & generation, connection & disconnection of branches & buses, addition and removal of induction and
synchronous motors.
7. OPTIMAL POWER FLOW ANALYSIS:
CYMOPF, the Optimal Power Flow analysis module of PSAF, supplements the analytical capability of PSAF by allowing the user to engage in
advanced system planning studies to optimize system performance, examine cost-efficient operational planning alternatives, articulate
system control strategies and rationalize equipment utilization, resulting in better overall system asset management.
8. HARMONIC ANALYSIS:
It features a number of analysis, including frequency scan, voltage distortion and current distortion calculations on balanced
and unbalanced systems; and covers both single phase and full three-phase modeling capabilities.
CYMHARMO includes a number of analysis, including frequency scan, voltage distortion and current distortion calculations on balanced
and unbalanced systems. CYMHARMO allows the user to easily detect resonant frequencies due to capacitor banks, and to model non-linear
loads and other sources of harmonic currents such as converters and arc furnaces. These capabilities make it possible to evaluate the impact
of non-linear loads on the electrical network.
