摘　　要：复杂电能质量扰动事件包含多个相关的基本事件和多个扰动事件源。在对复杂扰动事件的类型和时空特征进行分析的基础上,提出一种复杂电能质量扰动事件源定位方法。采用原子算法检测扰动事件,给出根据各基本事件的起止时间进行扰动区段划分的方法;采用叠加原理对瞬时功率进行分析,提出根据扰动能量的极性对各区段扰动事件源进行定位。算例结果表明,该方法能够实现复杂电能质量扰动事件源定位。Complex power quality disturbance events contain multiple related basic events and disturbance event sources. Based on the analysis of the types and spatial-temporal characteristics of complex disturbance events,this paper proposes a source localization method for complex power quality disturbance events. The atomic decomposition algorithm is used to detect disturbance events. And the disturbance interval division method according to the starting and ending time of each basic event is given. Then the superposition principle is used to analyze the instantaneous power. Therefore,based on the polarity of disturbance energy,the source localization method for each disturbance section is proposed. Results show that the method can achieve source location of complex power quality events.
