ABSTRACT:
A synchronous electric machine has a voltage and speed regulator, comprising a stator provided with a secondary winding and a rotor provided with a primary winding, intended for connection to a feeder grid (operating as a motor) or a user grid (operating as an alternator). The stator winding (ES) is coupled with a second stator winding (e) feeding a static rectifier circuit (R) whose output is connected to a superconducting energy storage winding (BS). The rectifier circuit is controlled by a computer (C) programmed to inject active and reactive power into the stator in such a manner as to attenuate transient conditions.
