ABSTRACT:
An electric energy storage and distribution system for a fluid-driven propeller, the propeller being connected to drive an AC generator, includes a planetary gear system by means of which rotation of the propeller is transferred to the AC generator motor, via a ring gear and a sun gear attached to a DC generator/motor, the DC generator/motor being connected to a battery. When the speed of the propeller is insufficient to drive the AC generator at a desired frequency and voltage, the DC motor is driven by the battery to either assist rotation of the propeller or the propeller can be braked such that the DC motor alone drives the AC generator. When an excess propeller speed is obtained, the propeller drives both the AC generator and the DC generator, the DC generator charging the battery. Conversely, when excess power is available through the power grid, the AC generator can be used as a motor to drive the DC generator via the ring gear, planetary gear, and sun gear to charge the battery.
