Wind energy has attracted more and more interest due to its clean, non-pollution and renewable features. In order to reduce wind turbine operation and maintenance costs, this research introduces an improved Back Propagation (BP) neural network technique for wind turbine drive train condition monitoring, especially for fault classification. In this approach, four types of fault signal, which are collected from main drive train components such as the main bearing, shaft, gearbox and generator, are used for fault classification. Firstly, in order to eliminate the effect of the difference of the orders of magnitudes, all the selected input signals are normalized. Secondly, to improve the BP neural network convergence efficiency and speed, improved learning algorithms are employed to train the proposed network. Thirdly, this paper introduces a new guideline to determine the hidden layer nodes. The test results show that the proposed network has real potential for wind turbine condition monitoring and fault classification.
