摘要
交直流互联系统发生换相失败故障将影响交流侧选相元件选相。对此,利用仿真分析法研究了换相失败对基于补偿电压突变量选相的影响。分析结果表明,换相失败引起的复杂电流暂态过程可能导致基于补偿电压突变量的误选相,并给出了不同故障状态下的误选相解决措施,可减小换相失败对选相的影响。
The phase selection of AC side phase selector was affected by the failure of AC-DC interconnected system failure occurred commutation. In this regard, the influence of commutation failure based on the amount of compensation voltage mutation selection phase was studied by the method of simulation analysis. The results show that the complex current transient process caused by commutation failure may be brought about the mistake selection phase based the sudden change of compensated voltage. Finally, the mistake selection phase solutions were given under different fault conditions, which could reduce the impaet of commutation failure on the selection phase.
