摘　　要：针对10 kV供电模式容量小、布点密、通道多、损耗大等问题,分析了国内外电网中压配电20 kV电压等级的现状,指出了采用20 kV中压配电的优势和郑州配电网用电负荷的特点。在负荷密度预测的基础上,分析比较了20 kV和10 kV两种配电电压的供电能力,并以具体工程为例进行了技术验证。结果表明,在郑州新区及其类似地区的高负荷密度地区宜提升中压配电电压。In order to solve the problem of 10 kV distribution network such as the low capacity,distribution density,multi-channel and large power loss,this paper analyzes the current situations of 20 kV voltage levels in medium-voltage power distribution network in China and abroad,and describes the advantages and load characteristics of distribution network in Zhengzhou City.Based on the load density forecasting,supply capacity of the 20 kV and 10 kV distribution voltage are analyzed and compared.Through an analysis of the examples,the results show that the medium-voltage distribution voltage should be improved in the high load density areas in Zhengzhou new district and other similar areas.
