摘　　要：串联补偿装电容器能有效降低线路所连接的两端点之间的电抗值,提高最大传输功率和系统运行的稳定性,并降低输电系统工程造价。文中就串联补偿电容器对线路保护装置的影响进行了研究,分析了问题产生的原因,找出了解决问题的方法,并提出了消除串联补偿装电容器影响的具体措施。the series compensation capacitor can effectively reduce the line is connected between the reactance value, improve the stability and maximum transmission power system operation, reduce the engineering cost of trans- mission system. In this paper the effect of series compensating capacitors on line protection device is studied, analysis of the causes of the problem, find a solution to the problem. Finally, put forward some specific measures to eliminate the influence of series compensation capacitor.
