Transient Stability Studies

Transient stability studies determine the response of a power system to the occurrence of faults, tripping of a transmission line (with or without auto-reclosing), tripping of a generator, or load shedding.

Such studies typically evaluate generator frequency and internal angle, bus voltages, and power flows before, during, and immediately after the transient disturbance to determine if the system remains stable after the disturbance.

CYME International’s Transient Stability Analysis program is generally used for transient stability studies. It includes extensive models of synchronous machines, exciters, stabilizers, and prime movers, and has the ability to simulate switching events, including line tripping and load shedding.
