Method for evaluating comprehensive state of transformer substation equipment based on equivalent degradation theory driving

The invention discloses a transformer substation equipment comprehensive state evaluation method based on equivalent degradation theory driving, which utilizes multivariate full-period monitoring data to cover various monitoring requirements of transformer substation equipment, including various sensor data such as temperature, humidity, current, partial discharge and the like, and comprehensively analyzes the data to evaluate the comprehensive state of the transformer substation equipment. The health state of the equipment can be comprehensively monitored; in combination with fuzzy analytic hierarchy process, an evaluation system is divided into four layers: an overall layer, an equipment layer, a criterion layer and an index layer, and the layering method enables state evaluation to be comprehensive and detailed, and can perform accurate evaluation for various equipment and state indexes; by constructing and applying a fuzzy consistent matrix and weight iterative calculation, the importance of each evaluati
