Communication angle analysis of a double output induction generator operating in sub- and super-synchronous modes

A rigorous performance analysis of the double output induction generator system with two controlled converters has been carried out including the effects of both the rotor side converter's commutation angle and harmonics as well as the supply side converter's harmonics. This is achieved by means of the hybrid induction machine model which allows for the changing states of conduction of the rotor side converter's thyristors. The variations in overlapping angle of the rotor side converter is obtained for a wide range of shaft speeds and for various firing delay angles.<>
