Mechatronic Modeling and Control of a Nonlinear Variable-Speed Variable-Pitch Wind Turbine by Using the Bond Graph Approach

چکیده
As wind turbines increased in size and power, control specifications became more challenging and regulation mechanisms more sophisticated. More and more reliable and powerful model control strategies are needed not only to keep the turbine within its safe operating region but also to improve efficiency and quality of power conversion. This paper mainly focuses on the mechatronic modeling and control of a 5MW Variable-Speed Variable-Pitch Wind Turbine (VS-VP WT) for the above-rated power operating condition. The principal parts of the wind turbine are modeled by using the Bond-Graph approach and the control strategy is realized by combining a torque control with a blade pitch control strategy by means of bicausality of the bond graph. The robustness of the proposed model control is verified and the simulation of the complete model is conducted for variable wind speed operation conditions.

One of the main tasks of the control systems in the wind turbines is to maintain the power of the wind when its wind speed proceed its nominal value. Because the failure to maintain the power in its nominal value in the region of the turbine curve damages the turbine and increases the mechanical stress. This object is obtained by controlling the pitch angle in the third region of the turbine cu...
