摘要

本文介绍了直流谐振发生的机理和危害、直流侧低频阻抗的扫描以及直流谐振的抑制措施。以滇西北至广东特高压直流输电工程为例

扫描了该工程直流侧的低频阻抗

提出并对比了直流谐振的两种抑制措施

给出了滇西北至广东特高压直流输电工程的直流谐振的最终抑制措施并验证了其抑制效果。介绍的50 Hz及100 Hz阻塞滤波器的直流谐振抑制措施在滇西北至广东特高压直流输电工程中得到了实际应用。

Abstract

In this paper

the occurrence mechanism and harm of DC resonance

scanning of low frequency impedance of DC side and suppression measures of DC resonance are introduced. Dianxibei to GuangdongUHVDC project is taken as an example

the low frequency impedance on DC side of the project isscanned

two types of suppression measures of DC resonance are proposed and compared

the final sup-pression measures for DC resonance of Dianxibei to Guangdong UHVDC transmission project is given andthe suppression result is verified. The DC resonance suppression measures of 50 Hz and 100 Hz blocking filter introduced in this paper is applied practically in Dianxibei to Guangdong UHVDC project.
