New Strategy

This paper presents a new simple control strategy for direct driven PMSG wind turbines, using no wind speed sensor. There are several strategies for wind turbine control. Operation of different strategies in terms of power smoothing is compared. New strategy is proposed to have more power smoothing. Performance of the proposed strategy is evaluated by MATLAB/ Simulink simulations and its validity and effectiveness are verified.

The paper presents a coupled electrical aerodynamic model for a three blade wind-turbine dynamic analysis. The model is based on a blade element representation of the aerodynamic load part combined with an aeroelastic beam element for the dynamic analysis of a real rotor blade, including top tower acceleration. The model involves reduced computation time enabling to be applied in control system hardware. Such an analysis is very promising for obtaining controllers involving compromises among contradictory targets such as energy capture maximization and mechanical stresses reduction in the aerodynamic part.

Yaw Control

Yaw system is an important part of wind turbine control system, yaw error is an important performance index of wind turbine, which has great influence on power generation. The wind utilization and the output of the power generation have been determined by the yaw error. In order to make the wind turbine better aligned toward the wind direction, reduce the yaw error, and increase the power generated by the unit, the angle errors of yaw control of wind turbine have been analyzed, in this paper, and the method of wind test, the strategy of yaw control have been studied respectively. Based on the results of the study, the method of wind test, the restart control strategy of yaw system and the performance of control strategy of yaw system have been optimized in this paper. In this way, the three important links are optimized, it will effectively reduce the yaw error as well as significantly improve the wind turbine generating electricity.
