Research on Maintenance Strategies for 110 kV Transformers Based on LEI Model
In China's power system,the large number of transformers and their extended service times signifi-cantly impact their cost-effectiveness.The service life of transformers is closely related to maintenance and opera-tion.Current transformer maintenance plans often prioritize reliability but give less consideration to economic fac-tors.This paper analyzes the impact of maintenance strategies on the service life of transformers using the Life Ef-ficiency 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.
