Condition monitoring and fault diagnostics of wind turbines

Condition monitoring and fault diagnostics is important for wind turbines to ensure safety and reliability. However, the application in wind turbine is still in initial stage. This paper analyses the frequent faults in wind turbines and determines the sensor configuration of a wind turbine. Architecture of condition monitoring and fault diagnostics system is built to monitor a wind farm. Methodology and algorithms based on vibration, noise and acoustic emission signals have been discussed to diagnose the fault of wind turbines.
