In this paper, without using the mechanical speed regulator, we propose a scheme that can control the output power of an induction generator by controlling the excited current. To attain this goal, an inverter is designed as a current controlled source, to supply an excited current for the induction generator. Furthermore, using the dq axes theory, a vector controller is designed by a digital signal processor (DSP) for controlling the inverter which supplies excited current appropriately in accordance with the wind speed to regulate the induction generator output power. Finally, the experimental results have shown good performances of the proposed inverter for control the excited current on induction generator. Thus, in applications of wind power generation, the proposed system can successfully obtain the variable speed constant frequency (VSCF) control without using the mechanical speed regulator in wind power applications.
