基于模块化多电平换流器的高压直流输电(MMC-HVDC)具有高度的可控性,其故障电流特性与传统的同步电源差别较大,可能影响电流相位差动保护的动作性能。推导了故障线路换流站侧和电网侧电流相量的表达式,对故障电流特性进行了深入分析;在此基础上,推导得了到单相接地故障和相间短路故障条件下故障线路两侧电流相角差的解析表达式;分析了故障类型、电压不平衡度、功率参考值等因素对故障线路电流相角差的影响,进而指出MMC-HVDC对电流相位差动保护动作性能的影响机理。在PSCAD/EMTDC中搭建了仿真模型,仿真结果验证了理论分析的正确性。
MMC-HVDC(Modular Multilevel Converter based High Voltage Direct Current) is highly controllable and its fault current characteristics are quite different from that of traditional synchronous power supply,which may affect the performance of current phase differential protection. The current expressions of the fault line at both converter station side and grid side are derived,and the fault current characteristics are deeply analyzed. On this basis,the analytical expressions of current phase angle difference between the two sides of fault line are derived under the conditions of single-phase grounding fault and phase-to-phase short circuit fault. The influence of fault type,voltage unbalance degree and power reference value on current phase angle difference of fault line is analyzed. And then the influence mechanism of MMC-HVDC on the performance of current phase differential protection is pointed out. The simulation model is built in PSCAD/EMTDC and the simulative results verify the correctness of the theoretical analysis.
