摘　　要：为了进一步提升窃电用户所在相线和线路节点的检测准确性,提出基于降序组织算法和递归模型算法的用户窃电检测新模型。该模型通过公共警报和电流差值的组合确认是否存在窃电事件。通过智能电表的旁路检测功能检测窃电事件发生的相线和中性线。基于“电路中窃电检测”报警信息和电表的“分流检测”供能,检测窃电事件用户所在的线路节点。为验证所构建模型的有效性,将所构建模型用于检测一个4节点配电系统实例中的窃电事件。实例分析结果表明,所构建的模型能够准确检测存在窃电事件的相线以及具体的配电线路节点。To further improve the detection accuracy of the phase lines and line nodes of place where the users steal electric,a novel model based on descending order organization algorithm and recursive model algorithm is proposed.The model confirms whether there is electric theft events by combining public alarms and current differences.The phase lines and neutral lines where the electric theft events happen are detected by the bypass detection functions of the smart electricity meters.Based on the alarm information of“electric theft detection in the circuit”and the power supply of“shunting detection”of the electric meters,this paper detects the line nodes where the user of the electric theft event is located.For verifying the effectiveness of the built model,the built model is used to detect electric theft events in a 4-node distribution system.The results of the example analysis show that the model constructed can accurately detect the phase lines and the specific distribution line nodes where there are electric theft events.
