Wind turbine generator is rotating machine. It consists of number of electrical, mechanical and electronics part. Some of them are very sensitive to electrical power fluctuation and environmental conditions. Temperature of mechanical and electrical component raises to higher value due to atmospheric condition or problem in components like lack of lubricant in gear box, improper setting of pitch motor, yaw motor brakes in wind turbine generator. If it persists in system for longer time then it may lead to permanent failure of generator bearing, gearbox, pitch and yaw motor. Gear box, generator and main bearing are main and costly part of wind turbine generator and located on same shaft called drive train. Its destruction and erection is not simple .It takes more time to restore from breakdown into service. That mean it is time consuming as well as expensive process. So it is possible to eliminate these problems by adopting condition monitoring techniques. These techniques also help to understand health of wind turbine. In this paper, Author discussed vibration analysis of wind turbine, oil analysis of gear box, temperature and thermography analysis of different components of wind turbine generator and also stated the benefits of condition monitoring to service provider, customer. Finally author provided suggestion to improve condition monitoring techniques.
