摘　　要：为提供一种有效的配电网线损管理手段,在现有配电网线损指标研究的基础上,采用区间法对线损指标进行划分,并建立不同线损区间的评价方法。将线损区间分为不合理损耗区、高损耗区、无功管理区、低损耗区,分别给出了合理和不合理损耗区间的评价方法,找出可能存在的不合理原因用以指导管理降损和技术降损。以山西某地区10 kV配电网为例,分析了对应的线损指标,找出线路存在的问题,并给出了相应降损措施。In order to provide a kind of effective management tool for line loss of power distribution network,on the basis of existing index research on line loss of power distribution network,interval method was used for dividing line loss index and establishing evaluation methods for different line loss intervals.The line loss intervals were divided into unreasonable loss in-terval,high loss interval,reactive management interval and low loss interval,meanwhile,evaluation methods for reasonable and unreasonable intervals were established respectively.Unreasonable reasons probably existing were found out for guiding management on loss reduction and technical loss reduction.Taking 10 kV power distribution network in some region in Shanxi province as an example,corresponding line loss index was analyzed and existing problems of the line was found out, meanwhile,related line loss reduction measures were proposed.
