【摘要】：針對基于事件辨識的故障診斷方法難以用于離散事件較多的電力電子電路這一問題,文章建立了電力電子電路的混合邏輯動態模型,將電路運行抽象為離散事件的變遷,并根據電路的故障模式確定電路的故障事件集和故障模型。文章應用了故障事件識別向量的概念,基于電路的故障模型僅通過對電路故障事件的辨識實現故障診斷,具有實現簡單、通用性好、診斷效果可靠的優點,以逆變電路故障診斷的仿真和實驗驗證了所提方法的可行性和有效性。
[Abstract]:In order to solve the problem that the fault diagnosis method based on event identification is difficult to be used in power electronic circuits with more discrete events, a hybrid logic dynamic model of power electronic circuits is established in this paper, which abstracts the circuit operation into the transition of discrete events. The fault event set and fault model of the circuit are determined according to the fault mode of the circuit. The concept of fault event recognition vector is applied in this paper. The fault model based on circuit realizes fault diagnosis only by identifying circuit fault events. It has the advantages of simple realization, good generality and reliable diagnosis effect. The feasibility and effectiveness of the proposed method are verified by simulation and experiment of inverter circuit fault diagnosis.
