| 摘 要： | 线损率是供电企业的一项重要经济技术指标也是衡量企业综合管理水平的重要标志。配电网的线损占电网总线损的40%以上。当配网出现三相不平衡时占得比例将大大增加。因此研究降低配电网线损的措施就显得尤为重要。通过分析三相不平衡线路的线损。推导出了线损增加率与相不平衡度的关系公式。可以直接用于配电网三相负荷不对称的线损计算中,并大大简化了分析计算工作中,为后续的工作做好了铺垫。

| Abstract: | The circuit loss rate is an important economical technical specification of power supply and it is a index to measure the enterprises management level.The distribution network line damages accounts for above 40% of the total main line damages.When the unbalanced three-phase of net matching happens,the proportion increases greatly.Through the analysis of unbalanced three-phase line damange,the relational formula of the increment of line damange with unbalanced phase degree is deduced.It can be directly used in the line damange computation of unbalanced three-phase loadindistributionnetwork.Thecomputationwork is greatlysimplified andhas completed the upholstery for the following work. |
