摘要
近年来，越来越多的城市都在修建地铁，地铁的供电网结构要比普通的电网线路复杂很多，对于继电保护的可靠性也有更高的要求。在修建地铁的过程中要合理布置地铁供电系统，供电系统保护的配置要准确，规范，从而保证整个地铁供电系统运行安全、可靠。本文主要就地铁供电系统继电保护方案展开了相关的研究，以供参考。
Abstract
The neutral insulation of high voltage main transformeris relatively weak, and it is easy to break down when high voltageoccurs. In this paper, a case of zero-sequence protection in thunderstormweather is analyzed. It is emphasized that the zero-sequence protectionof clearance and the protection of line side should cooperate with eachother. The optimization scheme is put forward in combination withthe fixed value setting of the factory, so as to improve the operationreliability of zero-sequence protection of clearance and the stability ofpower supply.
