1. A system comprising:
- an induction generator including a rotor and a stator;
a converter electrically coupled to the induction generator and configured to regulate a flow of electrical power between the induction generator and an electrical grid; and
a controller electrically coupled to the induction generator and the converter, wherein the controller is configured to operate the converter selectively in an electrical power generation mode and a diagnostic mode, and wherein the diagnostic mode of the controller is configured to instruct the converter to send an input signal to the rotor, receive an output signal from the rotor and the stator, and identify winding faults within the rotor, the stator, or a combination thereof, based on the output signals.

Abstract
A system includes an induction generator controller configured to operate an induction generator via a converter. The induction generator controller includes a diagnostic mode configured to instruct the converter to send an input signal to a rotor of the induction generator, receive an output signal from the rotor and a stator of the induction generator, and identify winding faults within the rotor and/or the stator based on the output signals.
