摘要
在分析城市电网电压等级合理配置重要性的基础上, 研究了国内外发达国家城市电网电压等级配置的现状。通过对电压等级合理配置的技术经济比较和对电压等级合理配置方案的分析,提出合理配置我国电压等级应简化变电层次,提高中压配电电压。
Based on the analysis of the essentiality for rational scheming of voltage levels in urban electric networks, the authors investigate the present situation about voltage level scheming in some cities in China as well as in developed country. By means of technical-ecomomical comparison of rational shceming of voltage levels and the anaysis on rational selection of voltage levels, a principal conclusion for rational voltage level scheming in China is obtained, i.e., simplifying voltge levels, boosting medium voltage level.
