Analysis of Power Supplying Characteristic Following Load Pattern Using EMTDC and Proposal for Optimal Operation

EMTOC를 이용한 전기철도에서의 차량부하 패턴에 따른 전력공급 특성 해석 및 최적운전방안 제안

Following the needs for increment of public transportation system electric railroad system should be expended. There are several solutions to expend. One of these solutions is to reduce the interval between two railroad vehicles. However, it cannot be reduced too much because reduction of interval means increment of loads and induces supplying voltage decrement. In this paper, voltage variation according to railroad intervals is simulated and optimal operation in railroad system is proposed.
