전기철도 배전망을 활용한 팬터그래프 방식 충전시스템에 관한 연구

초록

In the industrial fields have being accelerated the development of alternative energy resources because of restriction of environment pollution and increasing oil price at the world. Most of conventional vehicles are reason of environment pollutions. For these reason, interest in electric vehicles are increasing because of which is solution of reducing the environment pollution issues. Although a local autonomous entity had tried to replaced CNG buses for operating electrical buses, electrical buses have intrinsic problems such as charging/discharging sequences, connector issues and charging time. For these reason pantograph-type automatic charging technology is being developed for mating the environment of bus garages in nation. However, that has some problems such as initial price, room of charging infrastructure and electric power supply. In this paper, therefore, proposes methodology of using railway power supply system. It has been verified under suitability and balidity of charging and discharging scenario using electric bus charging system simulation model based on MATLAB Simulink and PSIM.
