摘要

纵观目前国内已投运和在建的18个直流输电工程

关于直流停运的事故原因中

由于直流输电换流阀水冷系统故障而停运几乎占到所有事故原因的1/3。笔者主要通过对800 kV向家坝—上海直流输电工程复龙站换流阀塔内水路结构改进的描述

以及分析向家坝—上海直流输电换流阀中与贵州—广东500 kV直流输电换流阀的区别

希望能够对今后直流输电换流阀的设计提供一些经验和方法。

Abstract

Of all the faults about system breakdown in 18 UHVDC transmission projects in China

about one third is attributed to the cooling system of HVDC transmission thyristor valve.Therefore

the modification of the water-way structure in the Fulong substation’s thyristor valve tower in 800 kV Xiangjiaba-to-Shanghai UHVDC project is described

and the difference between the valve towers in 800 kV Xiangjiaba-to-Shanghai UHVDC project and 500 kV Guizhou-to-Guangdong UHVDC project is analyzed

in order to provide some information for the design of similar valve towers.
