Wind Power Generator and Coupling

摘要

A wind turbine rotary shaft is coupled to the rotary axis of a grid connected generator/alternator by magnetic means to feed power to the grid at all rotation speeds of the turbine shaft that exceed the generator speed when it acts as a motor power by the grid. The coupling is a generally circular first plate having a magnet array at the end of the generator shaft. The rotary axis of a turbine is likewise connected to a second generally circular plate. The second plate is electrically conductive, but not magnetic and is offset but adjacent to the first plate. When the turbine shaft is turning faster than the generator shaft more power is fed into the grid by the generator/alternator.

主权项

1) A fluid flow power generation system comprising:
a) a fluid driven rotary turbine blade assembly, b) a first rotary shaft having a rotary coupling to said rotary turbine blade assembly, c) a first conductive plate orthogonally coupled to said first rotary shaft, d) an electric dynamo machine (EDM) having a rotary axle, wherein the EDM is energized by an electric power grid to run at a constant rotary speed, e) at least one of a second plate coupled to rotate in the plane thereof to the rotary axle, the second plate having disposed parallel to the plane thereof an array of permanent magnets, each magnet in the array having the north and south poles thereof oriented toward opposing sides of the plate, wherein for each magnets in the array, the north and south poles are at the opposite axial orientation with respect to the immediately adjacent magnets in the array, f) wherein the first and second plates are disposed spaced apart but sufficiently proximal to each other such that the rotary speed of the first rotary shaft being excess of the constant rotary speed will cause the EDM to generate more power into the electric grid than is consumed by its rotation at the constantly rotary speed.
