摘要
总结了主要发达国家或地区城市电网电压序列的现状及发展历程,分析了影响电压序列配置的主要因素,建立了4类典型区域的电网模型,分析了8种可行的电压序列配置方案的技术经济指标,并比较了不同电压序列及网络配置方案的供电可靠性,提出了在电压序列优化配置实际工作中应注意的主要问题。
Present situation of the configuration of voltage grades for urban distribution network in some developed countries and regions and its development course are summarized. The main factors influencing the configuration of voltage grades are analyzed; four typical regional power network models are built and the techno-economical indices of eight kinds of feasible schemes of voltage grade configuration are analyzed; the comparison of power supply reliability of different voltage grades and network configuration schemes are performed, and main problems, which special attentions should be paid to during practical optimal voltage grade configuration, are pointed out.
