Abstract
In order to deeply understand the dy-namic characteristics of the wind turbine tower, and solve the problems during the operation of the vibration of the tower. Research on modeling method for tower finite element equations of dy-namics,established the tower dynamics equation;based on Dynamics equations,the method to calcu-late the modal of the tower,tower foundation stiff-ness,mass and stiffness of tower tower to tower modal tendency,to provide theoretical reference for the wind turbine tower manufacture,installation process.Based on the dynamic equation,the solu-tion procedure of tower dynamics accordingly,and then designed a variable pitch control method based on multi obj ective excitation slow tower, wind farm simulation and experimental results show that this method can effectively reduce the vibration of the tower alarm,reduce wind machine downtime,and improve power capacity.关键词
