摘要
鉴于珠江新城采用220/110/10/0.4kV四级电压供电出现的问题,在总结20kV电压供电优势的基础上,对广州新城应用20kV中压配电系统进行了探讨,结论表明应用20kV电压等级既能节约资源,又能节省投资,是解决高负荷密度地区供电困难的有效途径。
In view of the power supply problems caused by using 220/110/10/0.4kV voltage series in Pearl River New City, basing on summing up the advantages of 20kV power supply, application of 20kV medium voltage in Guangzhou Metro is discussed. It＇s concluded that application of 20kV voltage level will lower the line loss as well as investment. It is an effective way to solve power supply difficulties in the areas of high load density.
