Abstract
When designing the main wiring scheme of the substation, it is necessary to comprehensively consider the problems of dense power grid, high system stability and outstanding short-circuit current problems, and improve the reliability of power supply according to the actual situation of urban development. This design plan optimizes the main wiring form, and conducts optimization research from the three aspects of reliability, flexibility and economy. After technical and economic demonstrations, the optimal design form of the main wiring of the 220kV substation is determined, and it has good economic benefits. The main wiring scheme of 220kV substation with social benefits.
