ABSTRACT:
The present invention provides a superconductive rotating electric machine drive control system that has higher efficiency and is smaller size and lighter in weight than conventional systems, and also provides a superconductive rotating electric machine drive control method to be implemented in the superconductive rotating electric machine drive control system. By the superconductive rotating electric machine drive control system and the superconductive rotating electric machine drive control method in accordance with the present invention, a control operation is performed so that the field current If2applied to the superconductive field winding of the synchronous rotating electric machine satisfies an equation for the field current If2in accordance with the variation of the electric power exchanged between the synchronous rotating electric machine and the power unit.
