Power setting method for doubly-fed wind generator

The invention belongs to the technical field of wind power generation power, and particularly relates to a power setting method for a doubly-fed wind generator. The best corresponding rotating speed omega*m of a motor is acquired through a best blade tip speed ratio of a wind turbine at the maximum working wind speed of a unit. The best rotating speed omega*m subtracts a feedback value omega m of the rotating speed of the motor to acquire a difference value delta omega m. The total losses of active power are acquired through a PI adjustment module and an amplitude limiting module 1. The power P*m output by the wind turbine subtracts the total losses to acquire a difference value delta P, and finally a set value P*g of the active power output by a doubly-fed wind generator is acquired, wherein P*m= T*m * omega*m, T*m is the set value of torque. The power setting method for the doubly-fed wind generator has the advantages that a rotating closed loop is added on the basis of an original doubly-fed wind generator power setting method, the speed of the system and the dynamic performance of real-time power matching are improved, the shock resistance capacity of the system is strengthened, and the stability of the system is improved.
