Wind PMG: Battery Charging Application – I
The market for small wind turbines is providing added electrification needed in remote areas. Many parts of the world are still running on electricity from batteries rather than electrical grids laid by national power corporations. Telecom companies who have to provide uninterrupted signals in remote areas rely on batteries and generators to get electricity. Another area that uses battery back up is Marine operations. Off grid wind turbines are proving to be increasingly valuble in these situations.
Wind speed is not always constant and it is usually highest during the night hours when people are not using much electricity. Storage of this night-time electricity can charge the battery and become an important method to utilize this electricity that could be lost.
Installing a small wind permanent magnet generator at remote sites can provide battery charging at a much lower cost than diesel generation or charging stations. Since there are no recurring costs with wind energy, the payback period of the initial setup cost is minimal.
