摘　　要：常规的电力系统二次回路故障分析方法主要使用AC\DC拓扑结构模型进行适配逆变故障分析,易受电压互感参数变化的影响,导致难以分析准确的故障链路位置。因此,本研究设计一种新的电气二次回路故障分析方法。首先,采集电气二次回路故障分析信息,设计电气二次回路故障分析算法,从而完成电气二次回路故障分析。实验结果表明,设计的电气二次回路故障分析方法的分析效果较好,可有效分析故障链路位置,具有可靠性,有一定的应用价值,为降低电气二次回路故障发生风险做出一定的贡献。Conventional power system secondary circuit fault analysis methods mainly use AC/DC topology model for adaptive inverter fault analysis,which can be easily influenced by changes in voltage transformer parameters,result‐ing in difficult to analyze the accurate fault link location.Therefore,a new method for analyzing electrical secondary circuit fault is designed in this paper.Firstly,the information of electrical secondary circuit fault analysis is collected,and the algorithm of electrical secondary circuit fault analysis is designed to complete the electrical secondary circuit fault analysis.The experimental results show that the designed method has good analysis effect,can effectively ana‐lyze the fault link location,has reliability,has certain application value,and has made a certain contribution to reduce the risk of electrical secondary circuit fault.
