摘要
Abstract
Aims to develop a scientific and rational decision-making method for power grid equipment renewal to achieve the healthy and sustainable operation of power grid enterprises.Basing on the theory of total life cycle cost(LCC),the Weibull model is introduced to calculate costs,and the time value of money is incorporatd to establish an optimization model.Thereby the optimal economic life and the minimum total life cycle cost are derived.A comprehensive performance evaluation system is constructed from the perspectives of economy,technology,and safety.It covers six indicators such as total life cycle cost and availability.The indicators are quantified through the Analytic Hierarchy Process(AHP)and normalization.Taking the communication line equipment of Company A as an example,the number of the renewal equipment is reduced by 329 km compared with the expected amount,and the equipment renewal budget is decreased by 26.45％.The results show that the proposed model effectively reduces the operating costs of power grid enterprises and enhances the comprehensive performance of the equipment,providing strong support for the equipment renewal decisions.关键词
