Power Transfer from Wind to Grid

Power is transferred from the wind to the rotor then passed through the gearbox, generator, and power electronics until it finally reaches the gird.Each stage of the power transfer has a certain efficiency. Therefore, each power transfer stage presents an opportunity to reduce the cost of energy from a wind turbine.
