The invention relates to the technical field of wind turbine generators, in particular to a wind turbine generator decoupling control method, device and equipment, a medium and a program product, and the method comprises the steps that based on the actual wind speed and an inverse system static curve, an inverse system torque expression and an inverse system pitch angle expression in a wind turbine generator are obtained; combining the rotating speed, the wind speed, the inverse system torque expression and the inverse system pitch angle expression of the wind turbine generator to generate a torque nonlinear function and a pitch angle nonlinear function; when the operation area of the wind turbine generator is switched between the transition area and the high wind speed area, the torque nonlinear function and the pitch angle nonlinear function are used for obtaining the required torque control quantity and the pitch angle control quantity respectively. Therefore, the problems that in the related technology, when the operation area of the wind turbine generator set is switched between the transition area and the high-wind-speed area, coupling of the two controllers is likely to happen, the generated power is lost, and the rotating speed is too high are solved.
