Abstract: Some embodiments relate to a method of sensing generator speed. The method includes detecting an AC waveform produced by a generator and determining a threshold voltage from the AC waveform produced by the generator. The method further includes determining generator speed by comparing the threshold voltage with the AC waveform. The generator speed may be determined by a time period between cycles of an output of the generator. Other example embodiments relate to a method that includes detecting an AC waveform produced by an alternative stator winding within the generator and measuring the period of the AC waveform to inversely determine generator speed.

Abstract: Some embodiments relate to a power management system that includes an engine-driven generator and a plurality of load switching and sensor modules that are located remotely from the generator. The load switching and sensor modules include power switching devices and/or sensor circuits. In some embodiments, the power switching devices are operated to selectively provide protected power from a breaker to loads. The power management system further includes a generator controller that is mounted to the engine-driven generator. The generator controller is configured to operate the engine-driven generator and the sensor and load switching modules. The generator controller is further configured to receive input signals from the load switching and sensor modules via a databus, and provide commands to the load switching and sensor modules via the databus to operate the power switching devices and selectively provide power to loads.
