Abstract

The new, 160 mile long Amtrak Northeast Corridor railway electrification project has four supply substations that connect 115 kV utility power to the 55 kV single-phase, AC traction power system. Eighteen autotransformer-paralleling stations are spaced along the route. Each autotransformer connects the overhead catenary to an auxiliary feeder line, with the rails tied to an intermediate point of the autotransformer. Each train draws power from two adjoining autotransformers. The protection scheme includes distance protection for the catenary and feeder lines, transformer protection for the power transformers and autotransformers, plus bus protection and backup protection. The protection scheme uses a specialized type of numerical distance protection relay optimized for railway traction systems. In the event of a fault on the protected part of the line, a trip occurs and the relay calculates the distance to the fault. All the autotransformers within that distance are automatically disconnected, and the relay attempts a reclose. If the reclose is successful, the autotransformers are reconnected.
新型交流铁路牵引电力系统的保护方案
新的160英里长的美铁东北走廊铁路电气化项目有四个供电变电站,将115千伏的公用电力连接到55千伏的单相交流牵引电力系统。18个自耦并联站沿线路间隔。每个自耦变压器将架空悬链线连接到辅助馈线,轨道连接到自耦变压器的中间点。每列火车从两个相邻的自耦变压器获取电力。保护方案包括接触网和馈线的距离保护,电力变压器和自耦变压器的变压器保护,外加母线保护和后备保护。该保护方案采用专为铁路牵引系统优化的数字距离保护继电器。在线路的受保护部分发生故障时,跳闸发生,继电器计算到故障的距离。在该距离内的所有自耦变压器自动断开,继电器尝试合闸。如果合闸成功,自耦变压器重新连接。
