Abstract

This paper addressed the issue of the three-phase load flow program for electric power distribution systems that include distributed generations. The equipment models were selected in order to consider imbalances among phases for the load flow analysis of distribution systems. Also, power equations and measurement functions are newly derived. The load flow analysis program developed in this paper was tested for the propriety of algorithm and convergence characteristics by case studies on test systems in various scales and types.

본 논문에서는 분산형 전원을 포함하는 배전계통을 위한 3상 조류계산 프로그램에 대하여 소개한다. 배전계통의 조류계산을 위하여 각 상간에 존재하는 불평형을 모두 고려할 수 있도록 계통 내 설비들의 모델을 선정하였으며, 전력방정식이나 측정함수 등도 새로 유도하였다. 본 논문을 통해 개발된 조류계산 프로그램은 다양한 크기와 형태의 시험계통에 대해 사례연구를 시행함으로써 알고리즘의 타당성 및 프로그램의 수렴성을 검증하였다.
