【 摘 要 】

Multiple indexes and multiple level comprehensive evaluations for wind power gear box focus more attention in recent days. Through the analysis of the state of wind turbine gearbox, fault hazard degree and other factors that is related with the internal temperature in gear box, environment temperature and the characteristics of wind speed, state evaluation index system of health indicators that is based on the current state of the age and the fault hazard health degree is established in this paper. Combined with the hazard matrix, current hazard degree is obtained. The effectiveness of adding health indicators is proved by examples.
