基于巴西美丽山工程提出±800 kV单12脉动特高压直流输电工程的避雷器布置方案。进一步研究整流站换流阀过电压、阀避雷器承受的能量和电流

选取交流相间操作冲击、6脉动换流器闭锁和Y/Y换流变阀侧绕组单相接地3种典型故障仿真计算

给出了整流站换流阀最大过电压

阀避雷器的最大能量和最大电流。研究结果为±800 kV单12脉动特高压直流输电工程相关设备的设计、生产和试验提供参考。

Abstract

Arrester scheme of ±800 kV double 12-pulse UHVDC is studied. Based on the Beautiful mountain projectin Brazil

an arrester scheme for ±800 kV single 12-pulse UHVDC is proposed. To make further study of valve over-voltage

valve arrester energy and valve arrester current

typical faults are chosen:inter-phase switching surge atAC side

valve blocking of 6-pulse converter and single-phase ground fault occurred at Y-Y winding of convertertransformer

which provide the maximum overvoltage of converter valve

the maximum power and maximum currentof valve arrester. The research results provide reference for the design

manufacture and test of the related equipmentof the ±800 kV single 12 pulse UHVDC transmission project.
