摘　　要：我国电力系统中变压器数量众多,其服役时间每增加一年,成本即能显著降低。变压器的服役时间与检修及运维情况息息相关。目前变压器检修计划多考虑变压器的可靠性,对于经济性的考虑相对较少。基于寿命效率指数(LEI)模型分析了变压器检修计划对其服役寿命的影响,并以年平均成本最低为目标建立了全周期寿命成本模型,通过布谷鸟算法求解出年平均成本最低时的检修计划,从而有效提高变压器检修的经济效率。最后搭建算例验证了该算法的可行性。In China’s power system,the large number of transformers and their extended service times significantly impact their cost-effectiveness.The service life of transformers is closely related to maintenance and operation.Current transformer maintenance plans often prioritize reliability but give less consideration to economic factors.This paper analyzes the impact of maintenance strategies on the service life of transformers using the Life Efficiency Index(LEI)model.It establishes a life cycle cost model based on minimizing the average annual cost and utilizes the Cuckoo Search Algorithm to determine the maintenance plan that achieves the lowest average annual cost,thereby improving the economic efficiency of transformers.Finally,a case study is presented to verify the feasibility of the proposed algorithm.
