结合配网自动化系统的实际，作者提出了一种利用分段现场监控单元(Field Terminal Unit，FTU)分段计算线路线损的方法。该方法利用FTU的监测数据统计负荷曲线形状系数及分段出口数据，把常规的线路线损计算转变成分段内的线损计算，这不仅提高了线损计算精度，而且可按形成的分段统计出分段内的支路损耗、配变损耗及管理损耗，便于配网线路线损的分析与管理，也可用于电度计量系统中的防窃电管理。

In this paper a new calculation method for line losses according to the practical situation of distribution automation in distribution network is presented, in which the data being monitored by Field Terminal Units (FTUs) are used to carry out the statistics of the load in each section and its waveform coefficient of load curve. With this method, the usual line loss calculation for the whole line is transformed into that in the sections. Not only the calculation accuracy is improved, but also the line losses of the branches, the losses in transformers in each section and sundry errors can be separately obtained. Therefore, the management for loss reduction in distribution network can be enhanced. Otherwise, this method can also be used in metering systems for guarding against theft of electricity
