<P>PROBLEM TO BE SOLVED: To provide a wind power station which does not impair power generation efficiency and which has favorable start-up performance and little vibration. <P>SOLUTION: The wind power station has a shaft 51 which is provided so as to be able to rotate around a rotation axis set in a vertical direction, and a vane 53 attached to the shaft 51, wherein the shaft 51 is rotated by a lifting force occurring at the vane 53 by a fluid flowing around the vane 53, and its rotation energy is converted into an electric energy. A cross section in a horizontal direction of the vane 53 is substantially the same between an upper end to a lower end, and a phase angle is continuously changed at a constant rate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
