摘要

为了研究换流站交流滤波器母线接入高抗后

操作该高抗产生的过电压

详细分析了切母线高抗引起的截流过电压和合闸过电压

并建立了换流站接入系统的EMTP模型

对母线高抗的操作过电压进行仿真计算。研究结果表明

随断路器截断电流值的增大

由分闸产生的操作过电压（包括截流过电压、断路器断口恢复电压和恢复电压上升率）较高;而合母线高抗未产生谐振过电压

也没有滤波器在合闸过程中过载。得出

在高抗侧并联一组避雷器能够有效地限制此过电压。

Abstract

In this paper

connecting system EMTP model of converter station has been built.Frequency scan is used to get the relation of system resonant frequency with bus voltage when AC filter bus shunt-reactor is connected in.Operating the bus shunt-reactor can cause overvoltage.Calculation results indicate that no resonant overvoltage generated during bus reactor closing and no overload generated during AC filters closing.However

with the increase of chopping current

this overvoltage generated by opening bus reactor（including breaker TRV and RRRV） is higher.It is effective to restrict the overvoltage that a group of arrestors are installed in parallel at the reactor side.
