Neural Network Based Wind Turbine Yaw Control System Research

With the economic development of various countries,human beings have more and more demand for energy,and the shortage of resources of traditional fossil energy and the pollution caused by the ecological environment are beginning to emerge.As a renewable and clean energy source,wind energy is a resource.The distribution is very wide,the energy is very large,and its importance is getting higher and higher.The use of wind power can generate considerable economic benefits and good social benefits,environmentally friendly and pollution-free,save the consumption of non-renewable resources,and alleviate the increasingly serious greenhouse effect.However,the wind is random,and its wind speed and wind direction are changing at any time.This leads to the fact that if the wind energy is to be utilized efficiently,the fan must be in a windward state at all times.This paper mainly studies the yaw control system in the wind turbine system to achieve the purpose of accurate wind.Firstly,the research on wind turbine and wind turbine yaw control system is carried out.The composition and working principle of wind turbine group are analyzed.Several different modes of yaw control system structure and principle and yaw are introduced.After the introduction of the wind energy theory and the analysis of the wind turbine,the model of the wind and wind turbine is established,and then the yaw angle is calculated by the measured wind data,and then the function and function of the neural network algorithm are proposed,and the neural network is adopted.The wind direction is predicted,and the simulation parameters are set by the actual data to verify the accuracy and feasibility of the wind direction.According to the functions and different working modes of the fan yaw system,the hardware and software of the yaw control system of the fan are designed,so that the wind turbine generator can perform stable and reliable yaw action.Finally,the MATLAB simulation software is used to simulate the whole fan.The simulation results verify that the yaw control system can perform accurate yaw action,making the wind turbine accurate to the wind,avoiding the fatigue action of the yaw system,and keeping the wind turbine in good condition.Work efficiency.
