摘　　要：分析了TCSC(晶闸管控制串联补偿装置)对平行双回线上的方向继电器的影响。文中指出:由于TCSC与固定串补不同,健全回线上的TCSC的运行方式对故障回线上的方向继电器有很大影响;而当健全回线上的TCSC被可靠旁路后,平行双回线中的方向高频保护装置均能正确动作。与固定串补相比,TCSC具有一定的优势,只要健全回线上的TCSC被可靠旁路,双回线上的方向高频保护装置均能正确动作。The Influence of TCSC on directional relays in parallel double-circuit lines is analyzed and it is pointed out that because of its complexity and indefiniteness the TCSC controller is different from SVC, so the directional relay in faulty line will be seriously influenced by the operating mode of TCSC in the healthy line and the influence depends on operating mode and parameters of power system. After the TCSC in healthy line is reliably bypassed the directional carrier current protection devices in both parallel lines can correctly operates. It shows that for parallel double circuit lines the TCSC has an advantage than SVC in this respect.
