The dynamic response of STATCOM has been studied during OOS condition in the presence and absence of STATCOM.
Full detailed modeling of STATCOM in two modes (reactive power control and voltage regulation operation) is simulated and the effect of STATCOM on the performance of the OOS relay has been investigated.
An analytical approach is developed to eliminate the negative effect of STATCOM on measured impedance by the OOS relay. This approach uses the voltage and current phasor information sampled by PMU in the remote bus of the generator.
