摘要
随着城市化进程的发展,各大城市都开始进行配电网络的建设以及改造,随着城镇农村电网改造的推进,低压电网的供电能力逐步得到增强,供给的电量稳定性和质量较以往有明显的进步和提升。而电网质量的提高也意味着线损率的下降,据统计,到目前为止,我国农村的线损率下降了百分之十三以上。虽然线损率有所下降,但是配电台区三相负荷不平衡问题仍然导致线损率居高不下。本文就当前配电三相负荷不平衡及线损的解决措施展开分析和讨论。
With the development of urbanization, all big cities begin to build and transform the power distribution network. With the promotion of the urban and rural power network transformation, the power supply capacity of the low-voltage power network is gradually enhanced, and the stability and quality of the supply of electricity are obviously improved and improved. The improvement of power network quality also means the decrease of line loss rate. According to statistics, the line loss rate in rural China has decreased by more than 13 percent so far. Although the line loss rate has decreased, the problem of three-phase load imbalance in the power station area still leads to high line loss rate. This paper analyzes and discusses the measures to solve the unbalance of three-phase load and line loss.
