Abstract

PURPOSE: To control a synchronous induction motor without using an exclusive transformer, by connecting the synchronous induction motor to a transformer for various loads in parallel, enlarging the adjustable range of the exciting device and correctidng phase difference which is varied.
CONSTITUTION: A synchronous machine 4 is made to be connected to the system by connecting directly a synchronous induction motor 4 to the synchronous machine 5, connecting the synchronous induction motor 4 to a transformer 14 for various loads which is already installed in paralle, detecting voltage vector difference at the both ends of a circuit breaker 6 with a detecting and control device 8 of phase difference and detecting and control device 7 of voltage difference, and adjusting field voltage of the synchronous induction motor 4. And, correction of phase difference which is varied by using the transformer 14 which was already installed is done by enlarging adjustable range of exciting device of the synchronous induction motor 4. Therefore, control can be done without using an exclusive transformer for the synchronous induction motor 4, and reduction of cost can be intended.
