Abstract:
This paper proposes a new method for the discrete control of active power and stator flux of permanent magnet synchronous generator in wind turbine. The main idea of this method is discrete control of the active power and stator flux from the perspective of the flux and angular load vector and Only by knowing active power and stator flux, the desired stator flux vector for the next moment is predicted. Then in order to generate the reference voltage vector, the space vector modulation is used which stabilizes the switching frequency and reduces the power and flux ripples. In this method all the calculations are done only in the stator reference frame and there is no need for translation to other reference frames. Compared to the vector control, this method has high dynamic response. The rotor flux and several machine parameters, including the stator inductance, are not interfered in the equations, which improves the robustness controller. Also, there is no need for integral proportional controllers and their coefficients adjustment. In this paper, MATLAB software is used for simulations. Comparison of the results of proposed method and vector control method optimized by the particle swarm algorithm, validates the high dynamic response, reduced active power and the stator flux ripple and overshoot in the proposed method.
