An operation system for a magnetic suspension wind driven generator comprises a digital controller. The digital controller comprises a digital signal processor TMS320F28335. An ADC module of the digital signal processor TMS320F28335 is connected with a signal conditioning circuit. A master control cabinet comprises a cabinet body and cover plates, wherein the cover plates are flexibly connected with frames through fixedly-connected connecting rod pins, wherein the frames are fixedly connected to the top and the bottom of the cabinet body correspondingly. Each channel comprises a bottom face and side walls, wherein the bottom face is parallel to the horizontal face, and the side walls are located on the two sides of the bottom face and inclined relative to the horizontal face. When each lead screw drives a pair of stretching and retracting rods extend out of the corresponding channel, a circular-truncated-cone-shaped sleeve moves to the end, smaller in transverse span, of a circular truncated cone portion along with a movable limiting sheet, and molded surfaces are separated for matching. The defect that no safety equipment is provided for field staff to control and adjust the rotation radians of the cover plates is effectively avoided.
