Wind PMG: Battery Charging Application – II
In marine environments where the sources of electricity are scarce, batteries are the only viable option and due to high wind speed at sea, these wind turbine battery charging options become a very profitable and convenient source. The overall cost of electricity is reduced. Also with battery usage the overall capacity of the site is doubled. The wind turbine produces the electricity and the battery stores the extra electricity.
The initial setup is simple. The connection diagram is shown below.
Since the generator is a permanent magnet one, the efficiency obtained in converting mechanical energy to electrical energy is maximum. It is more than 90% efficient, which means that more than 90% of the applied mechanical force by the wind is converted into electricity. Compared to 70% provided by traditional generators the amount of wastage is minimal. With such high efficiencies in permanent magnet generators, the fuel savings are more, the batteries last longer and overall cost of using electricity is decreased.
