Induction Generator Power Conversion and Control

High speed induction generators could operate as an effective primary or reserve source of electric power in a DC system using a power converter to control the generator output, circulate the varying amounts of reactive power between the machine terminals to maintain excitation, and rectify the output power. Frequency control at the stator output terminals is used to adjust the generator real power under a constant or nearly constant drive speed.

Reactive power circulation between an ideally balanced three phase generator and a six step converter is examined in detail, comparing two different switching schemes. With three switches conducting simultaneously, reactive power can be transferred directly between phases while a pattern with only two switches conducting at a time uses a DC capacitor to sink and source reactive power to and form all three phases. Steady state simulations demonstrate the system operation.
