Health Status Grading Evaluation Method of Subway Power Supply Equipment Considering Index Importance
To address the problems of"insufficient maintenance"and"excessive maintenance"in existing maintenance modes,a health status grading evaluation method for subway power supply equipment that considers the importance of indicators is proposed.First,the equipment health value was solved according to a combination of an analytic hierarchy process and fuzzy statistics.The importance of the index was considered,and the health status of the equipment was graded.Finally,a dry-type transformer was considered for analysis.The results show that the obtained results can reasonably characterize the health status of the subway power supply equipment,which is consistent with the actual situation,and verify the accuracy and feasibility of the method.
