摘要
Abstract
To reduce the huge losses of power transformer retirement in advance or delay in power grid,this article put forward a new method to predict technology life of power transformer based on DAHP algorithm and NonEquidistant GM (1,1)model.Firstly we build Health evaluation Index system of power transformer combining DAHP(improved analytic hierarchy process)algorithm from the characteristics of power transformer.And then calculate the health index value of power transformer.Secondly we set up technical life prediction model combining with the Non-Equidistant GM(1,1)model based on the past health index value of power transformer.Finally we verifies the feasibility of this method by applying our model in power transformer of 110 kV,220 kVand 500 kV which provides a reference for the retirement of power transformer.关键词
