    Abstract

    An angular position and velocity observer-based sensorless flux vector-oriented control scheme for a prominent doubly-fed reluctance generator has been presented and experimentally validated. This technology allows the use of the same partially rated power converter as the traditional slipring doubly-excited induction generator, while offering competitive performance with added cost benefits of high reliability and maintenance-free operation afforded by its brushless construction. The controller viability has been demonstrated on a laboratory machine prototype for emulated variable speed and loading conditions similar to those encountered in wind turbines.
