摘要

针对特高压直流输电系统接线方式从单极大地回线转为金属回线时

MRTB并联震荡装置是否出现故障

提出了一种基于电流分析的MRTB并联震荡装置的在线故障诊断方法。该方法首先通过在MRTB过零震荡装置进线侧和出线侧划定计算电流的闭合面

并在闭合面上运用基尔霍夫电流定律（KCL）

设计出一种计算MRTB并联震荡装置回路电流的方法

然后根据计算所得的MRTB并联震荡装置两侧电流特征

对并联谐振装置是否故障与故障类型进行诊断。最后

在±800 kV楚穗特高压直流极Ⅱ大地回线转为金属回线的2个实例中进行验证

验证结果证明文中所提方法的正确性和有效性。

Abstract

In order to confirm that the parallel oscillating device in metallic return transfer breaker（MRTB）is nor-mal or not

when the connecting mode of UHVDC system is changing from metallic return to earth return

this paperproposed an online MRTB parallel oscillating device diagnosis method based on current analysis. First

this paperdesigns a way to calculate the current of MRTB parallel oscillating device by delineating the closed surfaces and ap-plying the KCL law equation in those closed surfaces. Then

according to the characteristic of the calculated currentof MRTB parallel oscillating device

it can be diagnosed that the default status of the parallel oscillating device. Thecorrectness and effectiveness of this method proposed in this paper have been proved through the success and failureconversion cases of ±800 kV Chu-Sui UHVDC pole Ⅱ system.
