Abstract

This paper designs a 110KV substation. Through the analysis of transformer load, the capacity and number of main transformers are selected, and the main connection modes of 110kV, 35kV and 10kV are determined. By calculating the short-circuit current, it can be used to select the main electrical equipment to complete the design of transformer protection and the selection of distribution devices, and draw the main wiring diagram and the plane layout. Finally, we design a simple relay protection, and complete the design of the primary electrical part of 110kV substation.
