为提高混合三端高压直流线路及母线差动保护的速动性、灵敏性、可靠性与选择性

提出一种基于Hausdorff距离算法的新型高压直流线路及母线差动保护方案。当±800 kV混合三端直流线路发生故障时

通过线模电流故障分量判定故障方向

区分故障区域。对线路首末两侧电流波形进行实时短窗数据差异量化

用线路首末两端的电流相似度差异判定线路区内外故障及单双极选极。以T区送端(电网换相换流器侧)与T区两受端(模块化多电平换流器侧)电流和的Hausdorff距离差异作为T区母线故障识别保护判据。利用PSCAD建立混合三端直流输电系统模型

运用MATLAB验证所提方案。仿真结果表明:所提方案判据可耐受过渡电阻500 Ω

耐受过渡电阻能力强; 能在3 ms内快速可靠动作

可靠性高、快速性好; 对线路两侧通信精度要求低

都可快速识别故障区域及区内外故障

并实现故障选极。

Abstract

To enhance the rapidity

sensitivity

reliability and selectivity of differential protection for hybrid three-terminal HVDC lines and buses

a new differential protection scheme based on Hausdorff distance algorithm is proposed. When a fault occurs in ±800 kV mixed three-terminal DC line

the fault component values of line-mode current on both sides in T-zone are used as the fault direction discrimination basis of this scheme

and the scheme quantifies the difference of short-window data between the current waveforms of the first and last sides of the line

and uses the difference of current similarity between the first and last ends of the line to determine the internal faults and external faults

as well as the faults of unipolar and bipolar. The Hausdorff distance between T-zone sender(LCC side)’s current and two T-zone receiver(MMC side)’s total current is taken as the criterion of T-zone bus fault identification and protection. Then the hybrid three-terminal DC transmission system model is established by PSCAD and the protection method is verified by MATLAB. The simulation results show that the proposed scheme has strong ability to tolerate the transition resistance(500 Ω)

and has the advantages of high reliability and speediness to ensure quick and reliable action within 3 ms. The communication time accuracy requirement on both sides of the line is low

and the scheme has a certain ability to resist noise and abnormal data. Under different working conditions

the fault area and the faults inside or outside the area can be quickly identified

and fault pole selection can be achieved.
