摘　　要：提出了高压电力计量系统电能表电流线圈分流窃电故障检测模型。首先通过分析,得出电流互感器二次绕组端电压和通过电能表电流线圈的电流二者比值与电能表电流线圈分流窃电故障有密切的关系,及其与损失电量之间的关系。其次,设计用于电流互感器二次绕组端电压和通过电能表电流线圈的电流二者比值变化的故障检测模型,最后进行了仿真研究,以证明模型对故障检测的有效性。This article proposed shunt current electric larceny fault detection model for electric energy meter＇ current coil of the high voltage power metering system. First, through analyzing it obtains the close relationship not only between the ratio of current transformer secondary winding terminal voltage and the current passing the electric energy meter current coil and the larceny default of the electric current coil shunt current, but also the relationship with the loss electric quantity. Next, it designs the failure detection model for secondary winding terminal voltage and the electric energy meter current coil electric current the two＇s ratio change is designed, Finally, simulations are performed on the model to demonstrate the efficiency of the fault detection model.
