Abstract
One exemplary embodiment is method of operating an electrically excited synchronous machine (EESM) system. The system includes a converter operatively coupled with one or more stator windings, an exciter operatively coupled with one or more field windings, a controller operatively coupled with the converter and the exciter, and a power supply operatively coupled with the converter and the exciter. The controller determines whether a power supply fault condition exists and whether EESM system is operating in a motor mode or a generator mode. If the power supply fault condition exists and the EESM system is operating in the motor mode, entering one of a motor ride through control mode and a motor controlled braking control mode If the power supply fault condition exists and the EESM system is operating in the generator mode, entering one of a generator ride through control mode and a generator controlled braking control mode.
