The electrical power transient stability calculation program enables engineers to accurately model power system dynamics and transients by simulating system disturbances and other events.

Typical transient stability studies include identifying critical fault clearing time, checking generator rotor angle stability, assessing system stability margin, evaluating motor dynamic acceleration and reacceleration impact, preparing and testing load shedding schedule, computing fast bus transfer timing, calibrating and evaluating relay setting and simulating generator start-up.

You can split a system or combine multiple subsystems, simulate automatic relay actions and associated circuit breaker operations, and start or auto-start motors. Combined with enhanced plotting and graphical results, engineers can truly use transient stability analysis program to master power system stability studies.
