A model of a stand alone power supply comprising a diesel engine driven synchronous generator, a power conditioner, a bank of batteries, and an adjustable dump load is presented. The response of the power system to two different load profiles is included.

Generalized machine theory applied to a three phase twin stator squirrel-cage induction motor This paper uses generalized machine theory to develop an equivalent circuit model of a three phase induction motor comprised of two independently housed stator windings with one stator housing moveable, and a single squirrel-cage rotor whose bars extend the full length of the two stators.

A constant stator power controller for a wind-driven induction generator with double stator windings and a squirrel cage rotor common to both stators is described. The machine can feed power to the grid at variable speed and constant frequency. The torque of the generator is controlled by adjusting the angular displacement of one stator with respect to the other. This generator is called a tandem induction generator.A steady state model for the tandem induction generator is presented, Laboratory test results verifying the validity of the model. The paper also presents dynamic models for the wind energy conversion system for both the uncontrolled and the controlled operation of the tandem induction generator.The theoretical feasibility of the control system which eliminates all fluctuations in instantaneous output power is established.
