Abstract:

Based on the development status of modular substation at home and abroad, the layout ofmodular substation and conventional standard substation is analyzed. Through comparative analysis, thenew substation can effectively improve the utilization rate of land space, the flexibility of stationconstruction and the stability of power grid operation through standardized design, factory customizeddistribution and on⁃site assembly construction. Combined with the construction of a 110kV modularintelligent substation in Zhongshan Power Supply Bureau of China Southern Power Grid, the keytechnologies such as double⁃layer prefabricated cabin, modular integrated design, on⁃site assembly ofprefabricated cabin and intelligent operation and maintenance of substation are proposed, which providesa typical example for the promotion and application of modular intelligent substation.
