±800kV糯扎渡直流工程交流滤波器合闸超前相位对避雷器动作情况影响分析
Analysis on Effect of Closing Phase of AC Filter of ±800 kV Nuozhadu DC Transmission Project on Arrester Action
摘要
Abstract
Switching on of group filters at the converter station may cause different levels of transient impact on the system and frequent action and aging of the arrester. Therefore,this paper builds a simulation model for Nuozhadu DC transmission project by using PSCAD software and makes analysis and simulation on overvoltage,current and energy of the AC filter,and discusses reasons for frequent action of the arrester of AC filter. Corresponding results indicate switching on of the AC filter may produce impact in its own group filters and other group filters. As the closing phase of C type filter is 12°,the arrester of the own group filters acts,while when the closing phase is 18°,the arrester of the other group filters acts. Meanwhile, leading closing of a certain phase has no effect on overvoltage of the other phases,which means it can be considered three phases are in mutual independence.关键词
