| 摘 要： | 中压网络是城市轨道交通供电系统中的重要组成部分。经济合理地选择中压网络,有利于优化系统供电方案,减少工程投资,便于运营管理维护。通过对供电系统中压网络的组成结构和功能的介绍,采用功率矩法分析,结合实际工程对组网的方案采用35 kV、20 kV及10 kV等不同电压等级时的技术经济进行了比较。中压供电网络选择较高的35 kV电压等级是经济合理的。

| Abstract: | Middle-voltage network is an important part in the power supply system of urban mass transit.Selection of the middle-voltage network,both economically and reasonably,is in favor of optimizing power supple project,decreasing investment,benefiting introduction manage ment and maintenance.According to the structure and function of middle-voltage network in power supply system,this paper analyzes,by means of power moment,the characteristics of the middle-voltage network,compares the technical economy of the practical use of this network at different voltage classes,and holds that 35 kV class is more economic in the selection of a medium voltage network. |
