摘　　要：750kV月海线、海柴线加装串联电容补偿装置,在提升线路输送容量,提高电力系统稳定运行水平同时,对线路继电保护装置动作行为产生较大影响。针对输电线路加装串补装置后对电气距离、距离元件方向性、零序元件方向性、暂态过程的影响进行探讨,并提出减少串补电容影响的措施。The installation of the series compensators for the 750 kV YUEHAI power transmission line and HAICHAI power transmission line increases the power transmission capacity and improves the operation stability of the power system. However, the installation of the series compensators produces a greater impact on the operation of the relay protection for the power transmission lines. This paper analyzes the effect of the installation of the series compensators to the electric distance, distance protection element direction, zero - order element direction and transient process, and then gives the measures to reduce the effect of the series compensator capacitance.
