| The Transient Stability module enables engineers to accurately model power system dynamics and simulate system disturbances and events. Typical transient stability studies include identifying critical clearing time, motor dynamic acceleration, load shedding schedule, fast bus transfer timing, and generator start-up. You can split a system or combine multiple subsystems, simulate automatic relay actions and associated circuit breaker operations, accelerate or re-accelerate motors. Combined with enhanced plotting and graphical results, engineers can truly use this module to master power system stability studies. |
