20kV中压配电在城市高负荷密度新区中的应用

Application of 20kV Medium Voltage Distribution in High Load Densityof Urban Newly developed Areas

摘要: 针对城市高负荷密度新区电网规划问题, 讨论采用20kV作为配电电压等级的可行性。首先讨论了20kV电压等级在国内外的应用情况, 然后分析了采用20kV电压等级的合理性、可行性, 指出其采用20kV电压等级的注意事项, 最后以实例验证了20kV做中压配电电压等级的优势。

Abstract: For the phenomena that with the society development, the city new developed areas with high load density have emerged, the application of 20kV power distribution in the city new developed areas is discussed. The technical rationality and the supply feasibility of the 20kV voltage level are taken to specific analysis. Several issues needing attention are discussed.The advantages of the 20kV distribution are verified by a practical example.
