In order to accurately grasp the overall operating status of grid-connected wind turbines, an evaluation method based on an improved degradation model is proposed. Firstly, the evaluation model of fan operating status is constructed according to the AHP, and then an improved deterioration degree model is proposed based on the NSET algorithm; secondly, the weight coefficient of every parameter is calculated by the subjective and objective combination weight calculation method, and the ridge distribution membership function is used to determine the weight of each parameter. Membership degree matrix; finally, use the fuzzy comprehensive evaluation method to evaluate the unit's operating status as a whole. The evaluation of the operating status of the case unit shows that the method proposed in this paper can detect the abnormal temperature of the first-stage bearing of the gearbox of the unit in advance, which is helpful to timely discover hidden dangers in operation safety and avoid serious equipment failures.
