The marine Power Management System PMS is a complete switchboard and generator control system to synchronize the auxiliary engines of the ships by implementing automatic load sharing and optimizing the efficiency of the power plant.
If the mechanical regulator design is sensitive to small voltage fluctuations, the motion of the solenoid core can be used to move a selector switch across a range of resistances or transformer windings to gradually step the output voltage up or down, or to rotate the position of a moving-coil AC regulator. Early automobile generators and ...
Eco Marine Power, a company based in Fukuoka, Japan, develops and markets renewable energy based systems for ships and other vessels. The company's technologies use wind , solar and electric power to develop more energy efficient vessels with smaller carbon footprints .
A windmill ship, wind energy conversion system ship or wind energy harvester ship propels itself by use of a wind turbine to drive a propeller. They use wind power [1] through a mechanical or electrical transmission to the propeller. Where transmission is electric, storage batteries may also be used to allow power generated at one time to be ...
Large enough wind generators could produce a completely wind-powered electric boat. No such boats are yet known although a few mechanical wind turbine powered boats exist. In hybrid electric boats, if a boat has an internal combustion engine anyway, then its alternator will provide significant charge when it is running.
This is useful for large variable speed wind turbines, because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a synchronous generator is locked to the speed of the power grid and cannot speed up. So large forces are developed in the hub, gearbox, and generator as the power grid pushes back.
