摘要
介绍了发展20 kV城市配电网的背景,通过对20 kV电压等级技术经济指标的分析,阐述了建设20 kV配电网的必要性。结合陕西电网现状,对发展20 kV配电电压等级的主要限制因素进行了分析,最后提出了目前宜在陕西省一定范围内进行20 kV电压配电试点,并就试点区域的选择原则提出了建议。
This paper introduces the background to develop 20 kV urban distribution network, and expounds the necessity for constructing the 20 kV urban distribution network based on the analysis of technical and economical index of 20 kV voltage level. Combining the status of Shaanxi Power Grid, this paper analyzes the main limiting factor in development of 20 kV distribution voltage level, proposes that trial work on 20 kV power distribution should be conducted in a certain range of Shaanxi Province and raises some suggestions on selection principle for trial work region.
