摘　　要：电能作为现代社会最依赖的能源,降低电能损耗、提高电能质量至关重要。10 kV及以下配电网损耗占整个网络损耗的绝大部分,具有相当大的降损节能潜力。首先,介绍了线损产生原因及降低电能损耗、提高电压质量的措施。然后,对A地区现状公用线路进行分析。以某35 kV变电站为例,对其10 kV馈线进行了潮流计算分析,找出电网存在的问题,并提出相应的具体措施。最后,采用一种无功电压综合优化方法对变电站多条10 kV馈线进行无功补偿计算,验证了无功规划优化在降损和提高电压质量上的可行性和有效性。It is very important to reduce the electric energy loss and improve the power quality since electric energy is mostly relied on by modern society. The energy loss from 10 kV and below distribution networks accounts for most of the losses from an entire network, which means a distribution network has a great potential of loss reduction and energy saving. Firstly, the reasons of loss and the measures to reduce losses and improve voltage quality are presented. Then, a number of power lines in area A are analyzed. Taking 35 kV substation for example, the load flow of 10 kV feeders is calculated and analyzed, the ex- isting problems of distribution networks are found out, and the corresponding solving measures are put forward. Finally, the feasibility and validity to reduce losses and improve voltage quality are demonstrated by reactive compensation for 10 kV feeders from 35 kV substation.
