Main Transformer Capacity Release in 110 kV Large-Capacity Substation of Distribution Network
When the large-capacity transformer is applied,the primary problem is how to release the main transformer capacity.This paper presents some methods and establishes the model for capacity release of the large-capacity main transformer in 110kV substation.Thereby,the reasonable load rate combination can be achieved for 10kV overhead line and cable line when transformer is fully released,and the line load rate can be calculated with the increase of overhead line and cable line current,providing a solution for large-capacity transformer release in 110kV substation.
