Abstract: Improving power supply capability has been a focus of study in the construction of substations in urban areas. According to the problems of urban substations, a new type of construction scheme of urban substation is proposed through improving the direct power supply capability on the10 kV side of 220 kV substation, which is aimed to optimize the location of the substations in urban areas. Based on a comparison among the proposed scheme, the conventional 220 kV substation scheme and the 220 kV substations scheme which exports in 20 kV, it can be concluded that the proposed scheme is suitable for planning and construction of 20 kV substations in the urban area with high load density. Finally, a case study is conducted on a 220 kV substation in Guangzhou, which may provide references for the construction of substation in urban areas.

Key words: substation, power supply capability, planning, load density
