Abstract :
In this paper, the application of thyristor controlled phase shifter (TCPS) in damping power system oscillation is investigated. Analysis is carried out considering TCPS equipped with conventional lead-lag controller and with proportional-integral-derivative (P-I-D) controller. Parameters and gain settings of the TCPS controller are optimized using genetic algorithm (GA). Dynamic performances considering conventional phase lead-lag power system stabilizer (CPSS) and TCPS are compared. Analysis reveals that TCPS equipped with P-I-D controller improves the dynamic performances significantly as compared to that of conventional power system stabilizer.
