开绕组无刷双馈风力发电机最大功率点跟踪直接转矩模糊控制研究
Research on the Maximum Power Point Tracking of Brushless Doubly-Fed Wind Power Generator with Open Winding Direct Torque Fuzzy Control Strategy
摘要
Abstract
Based on the principle of wind power generator maximum power point tracking ( MPPT ), combined with the special structure of brushless doubly-fed machine,which does not have brushes and slip rings, and allowing for the adopted double stator magnetic field modulation method,so that the capacity of required converters is smaller,then a novel scheme of direct torque control and fuzzy control inn brushless doubly-fed generator system is proposed,which the control winding is opened and fed with dual two-level converters. The principles of each part,i. e. the maximum power point tracking,the open winding strategy,the direct torque control,and the fuzzy control are all explained in detail. Then the MPPT of brushless doubly-fed wind power generators with the open winding direct torque fuzzy control strategy model,i. e. the control winding is fed with dual two-level SVPWM converters,is built and researched using the Matlab/Simulink software. The excellent performances are obtained by the simulation results. Finally, the correctness and feasibility of the proposed strategy are confirmed by the semi-physical simulation experimental platform,which can provide a good reference to further develop the semi-physical simulation experimental platform and the related control strategies.关键词
