摘要

特高压直流输电（UHVDC）针对站内接地故障的保护闭锁是S闭锁

移相过程作为其中第1个步骤对故障后过电压影响较大。为研究移相参数对站内接地故障过电压的影响

以向家坝至上海±800 kV直流输电工程为例

计算分析了不同移相启动时延、移相速度和移相方式下过电压特性。研究结果表明

移相启动时延对站内接地故障过电压影响较大

并验证了目前系统采用的移相速度和方式的合理性。

Abstract

S-blocking strategy is used to treat ground fault in convertor station of UHVDC. As the first step of the Sblocking strategy

phase-shift has a significant impact on the overvoltage caused by ground fault in the convertor station. In order to investigate the impact of phase-shift parameters on the ground fault induced overvoltage

the Xiangjiaba-Shanghai ±800 kV DC Power Transmission Project is taken as an example to analyze the overvoltage characteristics in the conditions of different phase-shift startup delay

speed and mode. The results show that the improved phase-shift startup delay has a more significant influence on the overvoltage caused by ground fault

and the existing phase-shift speed and mode for the project are suitable.
