It's well known that energy has been a critical problem that restrict economic development of all countries.Human must find a sustainable path for energy problem from a long term.The key of sustainable energy is sustainable.In this situation Wind Generation became a important path for solving energy problem.The thesis mainly research brushless doubly fed wind(BDFM) and brushless doubly fed wind generation (BDFWG) System.The paper unifies the domestic and overseas related regulations and the literature to discuss the control strategy of BDFM and BDFWG..Based on energy situation of all countries in the world,We deeply know the importance of renewable energy including wind energy.Based on analysising the characteristic of structure,the principle and development history of BDFM.We researched four operations about BDFM. asynchronous mode of operation,synchronous modes of operation,double-fed modes of operation and generator mode of operation.Based on d-q coordinates we derivated the BDFM's dynamic equation,electrical torque equation and mechanical movement equation.At last we researched control strategies about BDFM Field Orientation Control and Direct Torque ControlResearched two simulations about wind turbine rotor-dynamic simulation and static simulation And discussed three prime motors in the simulation system-DC Motor,Permanent Magnet Synchronous Motor and Asynchronous Motor.Developed a novel wind turbine simulation and designed a whole wind power generator system with BDFM including upper machine,simulator system and generator system,and did some experiment.Comprehensive analysised the modern control theroy application in BDFWG,mainly including four modern control theory-optimal Control, H_∞control,sliding mode control and intelligent control.We developed a novel mathetic model of decoupled power.Because of disadvantage of PID control,we designed decoupled power control of wind gneration based on auto disturbance rejection control(ADRC).The correct and feasibility of result was identifiedBased on the basic structure and design of Model ReferenceAdaptive Control and mathetic model of decoupled power Lindear Model Following Control (LMFC)-PI control was designed.We analysised LMFC-PI controller by computer simulation.
