1000kV串联补偿装置旁路隔离开关操作时开合电压的分析

Switching Voltage Analysis in the Operation of Bypass Disconnector of 1 000 kV Series Compensation Installation

1 000 k V串联补偿装置是世界上首次将串联补偿装置应用于特高压系统,串联补偿装置主要有提高送电能力、改善电力系统稳定性、降低电力系统损耗、改善线路电压分布的作用。通过对1 000 k V串联补偿装置旁路隔离开关操作时开合电压的分析,有利于对1 000 k V串联补偿装置旁路隔离开关及其他开合电压较大时隔离开关的选型。

1 000 k V series compensation installation is used at the first time in UHV system in the world with such function as improving power transmission capability, enhancing stability of power system, reducing loss of power system and improving voltage distribution of transmission line. The analysis of switching voltage in the operation of bypass disconnector of 1 000 k V series compensation device is helpful in type selection of the dsconnector and other disconnectors which switch higher voltage.
