Engine-generator with load bank and control system

摘要

A load bank comprises one or more load resistors connected to an engine-generator and a control system for maintaining a minimum generator load when necessary for optimal operation. The control system operates the load bank to mitigate harmful effects of generator neglect and maintains loading for efficient DPF regeneration while allowing the generator to quickly dump the load bank when real load increases.

1. An engine-generator and load bank system comprising:
an engine mechanically connected to and capable of driving an alternator;
said engine having an engine control module and a particulate filter;said alternator in electrical communication with an output bus and a load bank bus; at least one load monitoring device in electrical communication with said output and load bank buses; a generator controller comprising a load dump output and a load enable output, said generator controller in electrical communication with said engine control module; a load bank controller comprising a load enable input, a load dump input, a load sensor, and at least one load step output;
said load dump output in electrical communication with said load dump input;said load enable output in electrical communication with said load enable input;said load monitoring device in electrical communication with said load sensor; at least one load step contactor in electrical communication with said at least one load step output; and at least one load step resistor in electrical communication with said load bank bus by way of said at least one load step contactor; wherein said generator controller provides a control signal via said load enable output in at least one of the following cases: neglect and regeneration; and wherein said generator controller provides a control signal via said load dump output in case of a load spike.
