- W2362664978 abstract "A method to predict economic life of power equipments is put forward.Taking the maximization of annual average net income as the optimization objective,the decision of which one is more appropriate between overhauling and replacement is made based on comparing annual average net profit under the two conditions.Taking the power transformer as example,the economic factors and rules within its life circle,including profit,actual cost,risk cost and so on,are analyzed,and mathematical models for overhauling and replacement are established respectively.Finally,taking an actual 220 kV power transformer as the case,the empirical research on prediction of its economic life is performed.Research results show that the proposed models possess strong operability and the prediction results by the proposed models conform to practice.The proposed models are significant to the implementation of advanced management of electric power equipment by power grid enterprises,and are of practical significance for the prolongation of equipment life cycle." @default.
