Relay protection device is important for the stable operation of power system and protected electrical equipment.It is very important for the reliable operation of power system protection devices to select reasonable protection way and correctly conduct setting calculation.In the component parts of power system,distribution lines running conditions is bad,and risk of accidents is much higher than the other equipment,so the relay protection device is more important.This paper mainly discusses protection configuration and the computation of 220Kv high voltage transmission line relay.%继电保护装置对于整个电力系统的稳定运行以及被保护的电气设备都是重要的.选择合理的保护方式和正确地进行整定计算,对电力系统继电保护装置的可靠运行具有十分重要的作用.在组成电力系统的各部分中,输配电线运行条件恶劣,发生事故的几率要比其他设备高得多,它们的继电保护装置更为重要!本论文主要是针对220kV高压输电线路继电保护的配置及其整定计算来论述的.
