  • STATCOM은 계통에 무효 전력을 공급함으로써 모선 전압을 유지시키는 역할을 한다. 따라서 발전기들의 회전자 위상각과 같은 유효전력과 관련된 계통 변수들의 제어 능력은 없다. 그러나 여자기에 PSS와 같은 제어기를 설치하여 발전기 회전자 진동을 제어하는 것처럼 STATCOM에도 이러한 제어기를 설치함으로써 부가적인 효과를 얻을 수 있다.

  • This paper presents a dynamic simulation algorithm for studying the effect of Unified Power Flow Controller(UPFC) on the low frequency power system oscillations and transient stability studies. The algorithm is a Newton-type one and gives a fast convergence characteristics. The algorithm is applied to inter-area power oscillation damping regulator design of a sample two-area power system. The results show that UPFC is very effective for damping inter-area oscillations.
