Abstract:

Traditional wind turbine converter uses wind speed sensors to measure wind speed as a control conditioning signal, which makes the cost too high, and the measured wind speed has some delay, affecting the response speed of motor control. For this purpose the paper presents a new control strategy of synchronous permanent magnet wind generator-side converter. By using the combination of hill-climbing searching algorithm and synchronous motor vector control of decoupling to realize the maximum wind capture and variable speed constant frequency control. The wind turbine model and the synchronous generator wind turbine model are built on the Simulink platform. The simulation results validate the rapidity and feasibility of the control method.And it shows that the control strategy can be quickly and accurately to achieve control objectives. It omits wind speed measuring sensor and reduces cost compared with traditional control strategy.
