基于智能电表的窃电量和追补电费估算方法

Estimation of Electricity Theft Quantity and Retroactive Charge Based on the Smart Meters

目前的窃电量估算方法无法反映不同窃电方式造成的窃电量差异,对用户恶意错接、断开接线造成的功率因数的失真也缺乏辨识和矫正措施,导致窃电量和追补电费计算不合理。针对上述问题,本文利用智能电表分相电参量测量功能,对三相四线制供电用户提出了根据窃电方式估算实际用电量和实际功率因数的方法;将实际用电量估算值与同期抄表电量相减获得窃电量估算值,并利用实际功率因数估算结果对大用户功率因数补偿电费进行核查和追缴。对上海某区窃电大用户的算例结果表明,本文所提方法能更合理和全面地追缴违约使用电量、电费。

The current estimation methods for electricity theft quantity can not reflect the consumption differences caused by different ways of electricity theft,and it also does not involve the restoring the distorted power factor, caused by malicious wrong connection and disconnect. Therefore,with the smart meter phase measuring function,this paper puts forward the estimation method for electricity theft quantity and the actual power factor according to the actual way of stealing electricity,and obtains the estimated quantity of electricity theft by subtracting the actual power consumption estimation value from the synchronous meter reading quantity. Then the actual power factor estimation results are used for the verification and recovery of high power factor compensation fee. The results of practical application of one Shanghai electricity peak area show that the proposed method can be more rational and comprehensive for the recovery of default electricity consumption charge.
