Wind Turbines Operating State Identification Method Based on Transfer Component Analysis
The identification of the operating state of wind turbines is of great significance to the performance evaluation of wind turbines and the refined management of wind farms. However, the supervisory control and data acquisition (SCADA) data distribution of different wind turbines varies significantly. If the trained normal behavior model of single typhoon turbine is directly applied to the operating state identification of multiple wind turbines, the identification accuracy is low. In order to improve the recognition accuracy, it is necessary to conduct repetitive training for each wind turbine normal behavior model, which is a large workload.Therefore, a multi-wind turbines operating state identification model based on transfer component analysis (TCA) is proposed. Firstly, a variable optimization method based on the maximal information coefficient and back propagation (BP) double hidden layer neural network is used to mine the key influencing variables of wind turbine operating status. Then, the normal behavior model of wind turbine based on BP double-hidden layer neural network is constructed with the optimal variables as input and the power as output. Finally, based on transfer component analysis, a multi-wind turbines operation state classification model is constructed. The results show that the proposed model can solve the problem of data distribution differences between different wind turbines and improve the accuracy and efficiency of the operating state partition model.
