摘要
通过分析10kV自闭贯通线路短路和接地故障特征,建立了故障检测模型,对铁路自闭贯通线路发生相间短路故障和单相接地故障进行了仿真.仿真分析结果表明,利用此模型判断相间短路和单相接地故障类型及所在区间是可行的.
The characteristic for short circuit and earth fault of 10 kV railway power transmission lines for automatic block systems was analyzed, and a fault detection model was built. Simulation results show that it is feasible to detect phase to phase short circuit and single phase earth fault and determine the location of the faults with the proposed model.
