阳城—三堡输电工程中串联补偿电容器组技术条件的研究

Capabilities and Stresses on Fixed Series Capacitor of Yangcheng-Sanbao

山西阳城经山东东明到江苏三堡输电工程中 ,用常规串联电容器组进行补偿 ,来提高现有输电线路的输送能力。笔者研究了以金属氧化物电阻器( MOV)、旁路开关及并联间隙作为串补设备保护装置的相互配合原则和它们的技术条件。

In the Yangcheng Sanbao 500kV EHV transmission lines,a Fixed Series Capacitor(FSC)was used to increase the power energy transmitted through the lines.Based on these lines, the writer studied the coordination of the FSC with the Metal Oxide Varistor(MOV),the bypass breaker, the series sky gap, also capabilities and stress on it.
