Control Strategy of Pitching Motion for Floating Wind Turbine Platform Based the Fluid-impulse Theory
摘要
Abstract
The pitching motion of floating wind turbine platform with tension-leg is analyzed based on the fluid-impulse theory, and a feedback control strategy is proposed to apply the active damping to the pitch motion.The feedback control system is designed in the case of the electrical output is not affected.The 5 MW wind turbine with tension-leg platform provided by NREL was modeled using FAST software and is co-simulated with MATLAB/Simulink software.The simulation results show that the designed feedback control system can not only reduce the fore-aft displacement of the tower top, the fluctuation of the rotor speed and the electrical power output, but also reduce the tower base rolling moment to a certain extent by using the FAST and MATLAB/Simulink software and is helpful to improve the life of the tower.关键词
