An experimental investigation of a self excited induction generator operating in stand alone

The present paper treats the transient and the steady state modeling of an autonomous induction generator, in order to study its transient response as a function of several parameters. A simple method is proposed to determine the adequate excitation needed to reach the rated voltage in standalone operation. The efficiency of the recommended strategy is validated by a simulation model developed in Simulink environment to survey the process of the voltage rise up. Then, these results are tested by an experimental bench based on a 2hp-220/380V induction generator trained by a DC motor.
