摘　　要：对传统低压线损的计算方法进行分析,综合电量法和等效功率法的优点,提出了利用考核期内运行参数(实抄电量)确定线损指标的方法,并给出了电流方差的简化计算公式,简单实用,误差基本满足台区线损指标要求,最后给出了计算实例。After analyzing the traditional methods of the low-voltage line loss calculation, the method for calculating line loss index by parameters (copied electricity) in examined days is given in this article. It contains the advantages of electricity method and equivalent power method and the reduction formula for calculating current variance is given. This method is simple, applied and can meet the demand for the calculation of the line loss index in transformer district basically. An instance is given in this paper at last.
