| The application of wind power was high-profiled with its green pollution-free, the great amount of aggregates and renewable advantages, how to ensure the safety operation of wind turbines, and maximize the use of wind power become an important research topic. Based on the analysis of non-linear and non-stationary wind speed and direction change, we study on the bionic yaw control system of wind turbine based on the neuro-endocrine-immune regulation mechanism, to improve the performance of wind turbine yaw control.The paper has mainly done the research work of following aspects:1.Study on the structure and working principle of wind turbine yaw control system, based on establishment wind turbines constituent units of the yaw system mathematical model, to establish a mathematical model of the wind turbine yaw control system.2.Against the nonlinear and uncertainty in the yaw control system features, present bionic yaw control method based on the biological neuro-endocrine-immune regulation mechanism. Environmental information has been accepted through the artificial immune unit, to deal with control deviation, the control effect by artificial neural unit and artificial endocrine unit feedback, system parameters can be optimized by GA algorithm, so that improved the self-learning and adaptive capacity of the yaw control system.3.The technical and functional requirements of 10KW wind power yaw control system have been analyzed, to study the overall architecture and the constituent units of the yaw control system, designed bionic yaw controller with its software process algorithm based on the ATmega128.Through simulation experiment, the results show that the method is feasible and effective. |
