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 I f2 applied to the superconductive field winding of the synchronous rotating electric machine satisfies the following equation (11) in accordance with the variation of the electric power exchanged between the synchronous rotating electric machine and the power unit: I f �¢ 2 = E 2 / k 4 �¢ n 2 �¢ v = V t cos ¸ - r 2 �¢ I 2 + V t �¢ sin �¢ ¸ - x 2 �¢ I 2 / k 4 �¢ n 2 �¢ v
where I f2 represents the field current applied to the superconductive field winding the synchronous rotating electric machine, I represents the line current, E 2 represents the induced electromotive force of the synchronous rotating electric machine, V t represents the terminal voltage, k 4 represents the constant, n 2 represents the number of winding wires in the superconductive field winding, ½ represents the flotation speed of the synchronous rotating electric machine, ¸ represents the power factor angle, r 2 represents the resistance of the synchronous rotating electric machine, and Ç 2 represent the reactance of the synchronous rotating electric machine. |
