Abstract :
The external controller (EC) of a series flexible AC transmission system (FACTS) device, which is the series capacitive reactance compensator (SCRC), can provide effective damping of low-frequency oscillations in a power system. The saturation limiter in the EC is used to enforce practical limits resulting from system restrictions, such as equipment and component ratings. The effect of saturation limits on the overall system dynamic behavior is analyzed. Also, a systematic nonlinear tuning method is proposed to determine the optimal values for saturation limits.
