Synchronous operation of a rotating power electronic brushless doubly-fed generator

This paper presents the synchronous operation of a novel generator termed as the rotating power electronic brushless doubly-fed induction generator (RPE-BDFIG). It is shown that the generator operates well at the synchronous speed of the main machine, delivering the desired power to the grid. Furthermore, it is illustrated that the RPE-BDFIG behaves similar to a synchronous generator in the synchronous mode. The closed-loop control of the generator is implemented in real-time, and the current and voltage waveforms of the stator and rotor of the RPE-BDFIG are experimentally analyzed. The paper highlights the stable operation and full control of the generator during synchronous mode.
