The present invention relates to a wind power generator. More specifically, front and rear generators generating power by the rotary power of front and rear blades separately and adversely rotating are installed in a nacelle unit. The nacelle unit is pivotally installed at the upper part of a yawing shaft connected to the upper part of a tower. The yawing shaft is connected to the lower part of the nacelle unit to be eccentrically installed to the front blade from the center of gravity of the wind power generator. A control unit controls the rear blade by applying loads to a rear generator when electricity generated from the front and rear generators by string wind is more than a standard value. The wind power generator rotates slantingly to a wind direction by a centrifugal force of the front blade when the rear blade stops to generate the optimum power amount while the rotary power of the front blade is reduced. The front and rear generators are respectively connected to the front and rear blades adversely rotating to each other so that power generating efficiency increases. Nacelle lower and upper covers forming the nacelle unit are formed to be easily separated above and below so the power generator is easily repaired without bringing the power generator on the ground and the safety of the power generator is improved. |
