摘要： One embodiment of the present application is directed to a protection technique for a back-up electric power generation system. This system includes an electric power generator, generator control circuitry, electrical output sensors to provide one or more corresponding signals, electrical switching equipment to selectively couple the generator to an electrical load, and electric power feeder conductors to route electric power from the generator to the switching equipment. The control circuitry is responsive to the sensor signals to determine if a shut-down condition exists as a function of a protection profile determined for the system. This profile may account for damage thresholds of the generator, the feeder conductors, and the electrical switching equipment for each of a number of different combinations of level and duration of electrical output as represented by the sensor signals.

摘要： A method of power transfer control among a plurality of power sources coupled through a distribution system. The method comprises determining, at each power source of the plurality of power sources, an assignment of priorities for each of the plurality of power sources. The method also comprises obtaining, at each power source, information indicating an availability of each of the plurality of power sources and determining a set of available power sources, and identifying, at each power source, a preferred power source and a standby power source from the plurality of power sources. The method further comprises determining to change the preferred power source from a first power source to a second power source in response to detecting a condition, and conducting the power transfer.
