Power systems analysis software

Simulation software and power systems analysis is global practice in electrical engineering. Initially, they were used to quickly solve the non-linear load flow problem and calculate short circuit currents, but their use has been extended too many other areas such as power system stability, protection, and coordination, contingency/reliability, economic modeling, etc. There are some software available by which load flow analysis can be performed as-

PSAF is a Canadian Application Software developed by CYME International Inc, for system studies and related works have been extensively used in load flow studies. Extensive integrated software programs perform the analyses of transmission and simulations. 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. PSAF software package is an integrated power system analysis that includes the electrical equipment parameter estimation for creating the network one-line diagram, graphic user Interface, associated database and database manager. It is directly applicable to both utility-type and industrial three-phase electric power systems. This database built in a wide selection of network equipment that has contains industry standard equipment characteristics. It offers both graphical and tabular data entry modes, plotting and customizing the simulation reports, user-preferred single-line diagram drawing options and sophisticated facilities for reporting.
CYME PSAF that develops an integrated suite for cable ampacity calculations and electromagnetic transients, as well as standalone application modular in power engineering. The integrated suite has a range of functions including load flow, short circuit, OPF, load balancing, load allocation/estimation, optimal capacitor placement, network forecaster, reliability, transient stability, harmonic analysis, dynamic motor starting, contingency, protection coordination, switching optimization, GIS overlay, earthling grid design and arc flash analysis.
