Abstract
This paper presents steady-state analysis and control of a wind-driven stand-alone 3-phase self-excited induction generator supplying a 3-phase induction motor. The induction motor drives mechanical load (such as a water-pump) which has a given speed-torque characteristics. The steady-state equivalent circuit of the system is analyzed using the node-admittance method and the results are utilized to determine the optimum operating conditions for maximum utilization efficiency.
