Abstract
According to the poor decoupling phenomenon and motor parameters dependent problem of doubly-fed wind turbine controlled by the traditional vector, this paper puts forward nonlinear control strategy based on sliding mode variable structure control and feedback linearization control. The control principle and the advantages and disadvantages of the two strategies are analyzed in details. Under PSCAD environment, the nonlinear control strategy is applied to DFIG vector control to establish the system model. Simulation results show that the proposed strategy can achieve the maximum power point tracking, and active and reactive power decoupling of doubly-fed wind power generation system. Comparative analysis of simulation results proves good decoupling effect. The system based on sliding mode control has stronger global robust-ness than the feedback linearization control system. The study establishes the foundation for the control system design and implementation of the doubly-fed generator.关键词
