Transient Stability


Transient Stability

The Transient Stability module enables engineers to accurately model system disturbances and events while performing studies such as load shedding, fast bus transfer, critical clearing time, and generator start-up. You can split or combine multiple subsystems, automatically simulate relay actions and associated circuit breaker operations, and accelerate or re-accelerate motors. Combined with incredible plotting and graphical results, engineers can truly master power system stability.
