차량-변전소 간 참여인수를 이용한 직류 도시철도 시스템 해석 알고리즘에 관한 연구

초록

This paper proposes a novel powerflow algorithm for DC electric railway system which is suitable to apply for real time system analysis. Based on the monitored vehicle load current, this algorithm calculates the participation factors between vehicles and substation. The current distribution factor based on the participation factor makes the system matrix simple to solve the powerflow equation linearly. Through the application to the DC railway system, this algorithm have been verified.
