Abstract:In order to meet the requirements of the scenario of power supply and power protection in the power system, and improve the emergency response capability and power supply reliability of the system, this paper applies a number of key technologies and methods such as compact weight reduction of transformer, shock absorption and isolation of equipment, verification of mechanical impact resistance, anti-corrosion of cabin roof, rapid layout of lightning protection device, modular design of secondary equipment and skid-mounted mobile substation digital twin. A large-capacity skid-mounted mobile intelligent substation with a main transformer capacity of 63 MV∙A and a voltage level of 110 kV is designed. Taking the large-capacity skid-mounted mobile intelligent substation that is actually applied in a new project of 110 kV temporary substation in Leshan City, Sichuan Province as an example, the effectiveness of this design is verified. The practice shows that this kind of power equipment has good promotion value and application prospects.
