Abstract: A system includes a generator coupled to an engine and configured to generate electricity from rotational movement of a shaft of the engine, a sensor configured to measure one or more of a parameter of generator output, engine speed, or engine shaft torque, and a controller configured to detect engine imbalance based on a frequency content of a signal output from the sensor in response to a contribution to the frequency content from another component of the system being less than a threshold value.

Abstract: Diagnosing equipment coupled to a generator. A condition of the equipment is diagnosed based on information provided by signals from a generator operationally connected to the equipment or other signals associated with an engine. Different types of degradation are distinguished based on discerning characteristics within the information. Thus, a degraded equipment component can be identified in a manner that reduces service induced delay.

Abstract: A locomotive control system measures actuating parameters of a locomotive propulsion system and monitors the actuating parameters according to a forcing function of operation of the propulsion system. A degraded component of the locomotive is identified by comparing actuating parameters generated according to the forcing function with actuating parameters expressed as a function of speed of another locomotive propulsion system, examining changes in the generated actuating parameters over time, examining oscillations in movement of the locomotive during gear shifting, comparing wheel speed decreases during another forcing function, and/or comparing a magnitude of a spectrum of the actuating parameters of with one or more designated magnitudes.
