Abstract: The comprehensive quality evaluation of distribution network equipment assets in the whole life cycle plays an important role in the development of distribution network enterprises. The quality evaluation of individual equipment is not representative, and it is not feasible to evaluate each piece of equipment. So, in this paper, the average quality level of similar distribution network equipment is evaluated from four aspects, procurement, installation, operation, and obsolescence, to make the evaluation results more representative and help distribution network enterprises to master the status of their equipment assets more efficiently. Under the evaluation index system, the analytic hierarchy process, the entropy weight method, and the least square method are used to get the comprehensive weight composed of the subjective weight and objective weight mixing. Then, by the fuzzy comprehensive evaluation method, the comprehensive weight is used to evaluate similar equipment in different regions and different equipment in the same region. Finally, the case analysis is carried out with the data of distribution cables and distribution transformers in H, Z, and J provinces to verify the feasibility and effectiveness of the proposed index evaluation system and evaluation model.
