摘　　要：为解决电气化铁路给与其相连接的电网带来的电能质量问题,分析了成都境内电气化铁路对成都电网继电保护装置的影响。介绍成都电网境内电气化铁路供电和成都电网保护配置的基本情况,分析电气化铁路对电网继电保护造成影响的原因,并建立成都电网的Simulink仿真模型,仿真分析牵引网3种类型的短路对成都电网继电保护的影响,得出结论:电气化铁路对电网的继电保护影响很小。Electrified railway brings power grid power quality problems, and poor power quality may cause malfunction of relay protection device. The influences of electrified railway on protection devices in Chengdu power grid was focused on in this paper.First of all, the basic situations of the electrified railways and relay protection configuration within Chengdu grid are described in this paper.Secondly, the influences of electrified railway on power grid are discussed theoretically.Finally, a Simulink model of Chengdu power grid is constructed, and the influences of electrified railways on Chengdu power grid is analyzed based on simulation under three kinds of short-circuit conditions.It comes to the conclusion that electrified railways have neglectable influences on Chengdu power grid.
