This paper presents a fault diagnosis system for wind power equipment based on condition evaluation. The state variables and characterizing operation situation of the wind power equipment are monitored real-time. According to state assessment guidelines,condition evaluation is conducted and the result of the evaluation is used to analyze potential faults. In addition,appropriate maintenance strategy is given. Through the early failure prediction,the maintenance after the event is changed to pre-overhaul and the overhaul plan can be arranged reasonably. In this way,the operation and maintenance efficiency of wind power equipment is greatly improved with maintenance cost reduced at the same time. As a result,reliable and stable operation of wind turbines is ensured. The wind power equip-ment fault diagnosis system based on this method is successfully applied in the CSG EHV Power Transmission Company’s over-haul and test center,and the application has proved that this method can effectively improve the real-timing and accuracy of fault diagnosis for wind power equipment.
