<p>The present invention provides a rotating electric machine system capable of preventing overcurrent at start-up without increasing components mounted on the rotor side of a rotating machine. The rotating electric machine system of the present invention comprises: a rotating machine; a power converter mounted on the rotor of the rotating machine and connected to an AC terminal of the rotor winding of the rotating machine; and a smoothing capacitor connected to a DC terminal of the power converter. The rotating electric machine system, in which the stator winding of the rotating machine is electrically connected to a power system through a switch device for opening and closing an electric path, further comprises: a rotation speed detector for monitoring the number of rotations of the rotating machine; and a control device for performing control so that the speed of the rotor of the rotating machine is increased or decreased to adjust the speed to a predetermined range of the number of rotations on the basis of the value detected by the rotation speed detector and the switch device is allowed to perform a closing operation to connect the stator winding of the rotating machine to the power system.</p> |
