Wind power generator

An apparatus comprising: a first input that receives a first rotational speed information of a windmill mechanically generated by a mechanical rotation detection unit; a second input that receives a second rotational speed information of the windmill based on an alternating current output of a generator attached to the windmill; and a controller configured to compare the first and second rotational speed information, to determine whether a difference between the first and second rotational speed information is greater than a predetermined value and to execute a predetermined anomaly processing in response to the difference being greater than the predetermined value.

Windmill rotation detection/management device and wind power generation system

A vertical axis type wind power station and a blade manufacturing process, which can stabilize the turning motions of blades and can raise the power generation efficiency by lightening the blades to smoothen the turning motions of the blades; a structure and method for mounting the wind-driven device of a wind power station, by which the wind-driven device can be easily disposed at the upper portion of a building; and a windbreak wind power plant for breaking the wind by using the vertical axis type wind power stations or wind-driven devices arranged along the shoreline or the like.
