A TECHNIQUE FOR THE STEADY-STATE ANALYSIS OF A SELF-EXCITED INDUCTIONGENERATOR WITH VARIABLE-SPEED

A method to analyze the steady-state open loop behaviour of the self-e xcited induction generator with an unregulated prime mover is presente d. The proposed method needs little mathematical effort and does not r equire an assumption about the generator speed. The proposed approach based on nodal analysis allows one to use arbitrary functions for the torque-speed characteristic of the prime mover and for the saturation of the magnetizing inductance without complicating the solution proces s. It always leads to a single equation for the frequency. An example is presented demonstrating the advantages of the proposed method. The analytical results are verified by measurement.
