摘要
Abstract
Low operational efficiency of light load transformer may cause waste of electric power resources. In allusion to the status quo of the main transformer operation mode in 110 kV substations of regional power grids during spring festival,this paper studies transformer loss and its economic benefits as well. It analyzes transformer loss characteristics of the 110 kV substation under different main transformer operation modes. Considering switching costs of the transformer and the break-er and risk cost of N-1 fault outage of the main transformer during adjustment process of the main transformer operation mode,the paper takes one adjustment scheme for the main transformer operation mode in one 110 kV regional power grid substation in Pearl River Delta area for an example and draws a conclusion that it is able to effectively reduce transformer loss by adjusting the main transformer operation mode.关键词
