The invention discloses an optimizing control method for uniform fatigue distribution of parts of a wind power station unit under active power regulation. DEL data modeling is conducted on the parts of the wind power unitunder an active power regulation mode, optimizing control over a wind power station with the complex terrain is conducted based on a DEL data model, the control strategy adopts anintelligent active power distribution strategy based on wind regime characteristic measurement, therefore, the optimizingcontrol method is suitable for the wind power station with the complex terrainand with the small wake effect; and by optimizing uniform fatigue distribution of the parts of the wind power station unit under active power regulation, the production-manufacturing and maintenancecosts of wind power generating equipment are reduced effectively, and the stability of a wind power generating system is improved.
