Abstract: In this paper dynamic analysis, closed loop voltage control and experiments on a self excited induction generator are presented. Electromagnetic torque, active power and reactive power are controlled under dynamic conditions of varied load, excitation capacitance and shaft speed, A closed loop voltage control scheme using a PWM Voltage Source Converter (VSC), dc link capacitor and a P-I voltage controller is proposed and implemented. This scheme generates constant voltage and variable frequency using the converter which also acts as a reactive power compensator. The frequency of stator voltage and current is varied by changing the error proportional gain making it attractive for wind energy conversion system. The simulation is done using MATLAB environment and the experimental results are also presented in this paper.
