Abstract

Abstract This paper the electrical power conversion system presents developed for a self-excited induction generator for wind turbine applications. In the wind energy conversion system a self-excited induction generator converts the mechanical energy into electrical energy. A B6 rectifier and inductor are utilized to maintain constant dc link current. The average power is converted entirely by the six-pulse converter, it's consists of a B6 current-source inverters. Line side current-source inverter supply currents into the utility line by regulating the dc link voltage. The active power is controlled by firing angle of converter with operated at inverter mode. The performance improvement of this proposed system by experiment using a 1 kW four pole self excited induction generator. The overall control system is implemented on six-pulse converter board. Experimental results are illustrated in order to validate performance of the proposed system.
