Effect of power line disturbance on loss of contact between contact wire and pantograph

전차선-팬터그래프 사이의 이선현상에 따른 전원외란이 보조전원장치에 미치는 영향

In this study, the dynamic characteristic of a contact wire and pantograph suppling electrical power to high-speed trains are investigated. The analysis of the loss of contact based on Power Simulator program software is performed to develop power line disturbance model suitable for high speed operation. It is confirmed that a contact wire and pantograph model are necessary for studying the dynamic behavior of the pantograph system.
