Life Cycle Cost Analysis and Optimization of Transformers
Transformer is the core equipment of the power grid,it is of great significance analyzing and optimizing transformer life cycle cost(LCC)for the improvement of economic efficiency of power grids.Based on the theory of LCC and the related costs of transformer,this paper firstly constructs the LCC model of the transformer;then analyzes its LCC,including the analysis of cost patterns and cost ratios under different voltage levels.Finally,the paper uses MATLAB software and the the whale optimization algorithm(WOA)to optimize the objective functions.The calculation example verifies the scientific reasonableness and superiority of the WOA,which has a certain guiding funcion for the control of LCC of the transformer in the engineering practice,and it is an important means of improving the efficiency of the power grid asset management.
