直驱式永磁同步风力发电动态特性的研究
Study of the dynamic characteristics of directly driven permanent magnet synchronous wind turbine
摘要
Abstract
The wind turbine has both the static characteristics and dynamic characteristics. The dynamic characteristics contain wind shear and tower shadow. Based on a complete model of directly driven type permanent magnet synchronous of wind turbine, the effect of pulsating torque rate caused by wind shear and tower shadow on PMSG wind power generation system is researched in detail. The equivalent air-powered torque is applied to perfect the traditional model of the wind turbine, which makes it more actual. The simulation model of directly driven wind turbine with permanent magnet synchronous generators (D-PMSG) is established in Matlab / Simulink and the operation of set at different wind speed is simulated. It is concluded that the pulsating torque rate caused by wind shear and tower shadow is triple the rotating frequency of wind power generation system. The simulation results is of more practical significance for directly driven permanent magnet synchronous wind power.关键词
