Modeling and Control For a Type-4 Wind Generator Based on AC/AC Power Converter

In this work a control scheme for a Type-4 wind turbine of 30 kW, is presented. The scheme is based on the control of currents obtained from the dq0 framework. The AC/AC power converter is designed based on the generator characteristics. By means of simulations with Matlab and Simulink several results are calculated when the power and the speed in the rotor are changed. The simulated results show that the proposed control has an adequate response to maintain a constant voltage at the load side and control the capacitor voltage and electrical torque in the electric machine in front of some disturbances.
