Power Systems Analysis Framework (PSAF) is an integrated power systems analysis software package that includes the Graphic User Interface, Data Base Manager, and Electrical Equipment Parameter Estimation for creating the Network one-line diagram and associated database.

PSAF is directly applicable to both utility-type and industrial three-phase electric power systems.

A wide selection of network equipment and controllers is supported by a built-in database that contains industry standard equipment characteristics. Every type of equipment features more than one modeling possibility depending on the purpose and extent of the simulation to be conducted.

PSAF offers both graphical and tabular data entry modes, user-preferred single-line diagram drawing options (including exporting to AutoCADTM) and sophisticated facilities for reporting, plotting and customizing the simulation reports.

The PSAF software is modular since each of the simulation and analysis modules listed below can be acquired independently from one another.

• Power Flow
• Motor Starting
• AC Contingency Analysis
• Optimal Power Flow
• Short Circuit ANSI and IEC Interface
• ARC Flash Hazard
• Transient Stability
• User Defined Modeling
• Breaker Rating Analysis
• Wind Energy Conversion Systems
• Voltage Stability
• Harmonic Analysis
• One Line Diagram Autocad(TM) Interface

Each of the simulation modules features industry-proven, state of the art modeling and solution techniques, making PSAF a reliable tool for demanding engineering analysis.

In the absence of detailed information, PSAF is capable of suggesting typical data for the system equipment. These estimating functions account for a wide array of industry manufacturing practices and respect the recommendations outlined in both North American and International calculating guidelines.

This includes advanced Overhead Line and Cable Parameter Estimation Programs.

Transmission line models are defined by their geometrical line configurations. Transposed and/or full three-phase un-transposed models including frequency dependency are supported for single or double circuit lines, with solid or tubular conductors, multiple conductors per phase and multiple neutral wires (segmented or not).



Underground cable constants are calculated single and/or three-core cables with either sheath or ground return.

PSAF is equipped with CYMVIEW that generates any kind of charts for all the analysis modules such as CYMSTAB, CYMHARMO, CYM-Motor Starting, etc. CYMVIEW is capable of managing the outputs of different modules and storing results for any number of simulations pertaining to the same module.
