The invention provides a floating type offshore wind power generation platform and a design and operation control method thereof.The floating type offshore wind power generation platform comprises a platform body and a wind driven generator installed on the platform body, the platform body is connected with preset anchor points of a seabed through a plurality of mooring lines, and the platform body comprises a plurality of buoys distributed in the circumferential direction; the buoys are mutually connected and fixed through truss structures, the wind driven generator is fixedly connected to one buoy, and an adjusting part used for adjusting the gravity center of the platform is arranged on the platform body. The gravity center and the net weight of the platform can be adjusted, the net weight of the balance weight unit, the extreme thrust of the wind driven generator, the maximum allowable inclination angle, the buoyancy center of the platform, the gravity center and other design parameters meet a certain mathematical relationship, and parameters such as the aerodynamic load of the wind driven generator, the tower footing bending moment, the platform inclination angle and the movement speed are measured through sensors and transmitted to a control system. The stability of the platform is regulated and controlled, and the operation stability of the floating platform and the aerodynamic efficiency of the wind driven generator are improved.
