초록

A power generator system that is suitable for use on medium-sized and large watercraft. The system includes a generator that is driven by a hydraulic motor that is coupled to the main engine through a variable hydraulic pump. In order to maintain a stable, substantially constant-frequency power output from the generator as the main engine operates over a wide range of operating speeds, a controller receives a power frequency input signal and a hydraulic pump speed input signal, and uses both of these input signals to generate an output control signal to ...
