摘　　要：基于长距离高压架空输电线路的分布参数 ,提出了关于“串联补偿电容器的安装位置、补偿容量和输送功率的定量关系”的计算公式。从提高功角稳定性考虑 ,在单点补偿时 ,最佳补偿方式是将电容器安装在线路中点。同时 ,分析了串联补偿对继电保护的影响 ,讨论了串联补偿可能引起次同步谐振问题及相应的解决办法。Based on distributed parameter of long HV overhead transmission line,the formulas are presented for the relation of compensation capacitors position and capacity to transmitting power in this paper.If all capacitors are located in single spot of line,in the term of improving power-angle stability,then it is the best option that compensation capacitor is placed at the middle of line.The effect of series compensation on relay protection is analysized.The problem of subsynchronous resonance caused by series compensation and the way to solve are discussed.
