500 kV Transformer Emergency Standby Applicability Assessment for East China Power Grid
Based on the abundant calculation research of 500 kV transformer standby applicability in East China power grid,this paper explores into the transformer standby applicability assessment method according to the original transformer technical parameters,and puts forward the assessment criterion and process.This method has been practically applied in 500 kV main transformer of Anhui grid.Studies show that the proposed method can make quick and efficient assessment without complex calculations,and can provide practical guidance for selecting centralized standby transformers.
