摘要
在综合华东电网500 kV变压器备用适用性研究大量计算结论的基础上,探讨了根据变压器原始技术参数来直接进行变压器备用适用性判别的方法,提出了华东电网500 kV变压器备用适用性的判别准则和判别流程.作为该判别方法的具体应用,进行了安徽电网500 kV主变备用的系统适用性研究.
Abstract
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.
