<p>A blade rotation angle autocontrol system for vertical axis wind power generator includes a generator (1), a wind wheel consisting of a plurality of blades (2),an anemoscope, a CPU, an encoder (4) and a rotation angle controlling device, wherein the wind wheel consists of blades installed at blade supports (21), a rotation shaft (22) is provided at rotation center of the blade (2), the blade (2) may rotate around the rotation shaft (22), and the rotation shaft (22) is connected with the rotation angle controlling device by a transmission device. The CPU sends commands to the rotation angle controlling device according to signals from the anemoscope and the encoder (4) and the rotation angle controlling device rotates the blade to preset angle so that each of blades obtains preset blade rotation angle at various position when the wind wheel rotates.</p> |
