불량계통을 위한 변형 고속분할 조류계산법

Abstract

불량한 전력계통에서의 조류계산시 수렴성을 개선하기 위하여 변형된 고속분할법을 제안하였다. 이 산법은 매 반복 삼각화 직접법 단계에서 구해지는 해를 즉시 전압과 위상각 수정에 활용되도록 변형시킨 것이다. 제안한 변형산법을 IEEE ?謬뵈? 계통에 적용하여 기존의 산법과 비교하여 본 결과, 정상계통에서는 수렴성이 뒤지나 불량계통에서는 수렴성이 우수함을 알 수 있었다.

This paper presents a modified algorithm to improve the convergency of fast-decooupled load flow (FDLF) method. The specific feature of proposed method is using of the most recent values of solution vector when solving the iterative recursive equations. This simple modification to standard FDLF method yields a more reliable convergence characteristics for ill-conditioned systems. A comparison of proposed method with the standard FDLF method is also presented for IEEE test systems.
