摘要

特高压直流输电具有大容量、远距离输电等优点

在我国"西电东送"工程中起着重要的作用。针对特高压直流输电中对变压器的影响、对交流系统稳定性的影响和对地下金属的腐蚀等问题

笔者介绍了特高压直流输电系统单极运行产生的地中电流对变压器励磁电流的影响

建立了等效电路计算流过变压器的直流电流

讨论了几种缓解直流偏磁影响的方法。

Abstract

In order to solve the problems caused by UHVDC transmission system when DC flows through the neutral point

such as DC bias

vibration

overheating and noise of a transformer

as well as corrosion of underground metal parts

this paper analyzes the influences of DC grounding current due to UHVDC mono-polar operation on transformer

and provides some solutions about reducing harmful effect of DC bias.
