Vrms control of self-excited induction generators feeding a three-phase AC load used in wind turbine

In this paper we interest to the output root mean square voltage (Vrms) for three phase Self-Excited Induction Generator (SEIG). This machine is very promising in renewable energy for uses in wind turbines to produce energy in the remote areas due to difficult geographical conditions. The voltage value of the SEIG terminal is not constant but she is varying with many system parameters like wind speed, external load and the capacitance value. Taking into account these parameters, we present in this paper the experimental results using the dSPACE card for control the PWM inverter to impose the Vrms value of the desired output voltage when the speed rotor and load changes.
