Control System of Permanent Magnet Synchronous Wind Power Generator with MW-level and Direct-driven
摘要
Abstract
Compared with the double-feed AC excited wind-power generation system, the direct-driven permanent magnet synchronous wind-power generation system possesses such features as simple structure, high generation efficiency and good operation reliability.The "uncontrollable rectifier + boost chopper + PWM converter" are adapted in conversion system.The relationship between duty cycle variation of power switch elements in a DC/DC link and variation of generator speed is analyzed.A new method for adjusting the duty cycle variation for maximum power point tracking is tested.Using the propased generation system, the maximum Wind-energy tracking control as well as the variable speed constant frequency ( VSCF)power generation can be implemented.The simulation and Experiment results have been carried out to verify the feasibility and correction of the proposed system.关键词
