基于LQG的独立变桨控制技术对风电机组气动载荷影响研究
Dynamics Loads Optimization Analysis of Wind Turbine Based on LQG Independent Pitch Control
摘要
Abstract
Multi-body dynamics model of wind turbine was build based on multi-body dynamics theory. Against the problem of uneven load distribution for wind turbine rotor, based on the traditional pitch control strategy, Individual pitch control algorithm was proposed based on the linear quadratic Gaussian (LQG); building control model in Simulink, achieving wind turbine system co-simulation, and compare with traditional control strategy. The results show that: LQG independent pitch control technology not only can achieve power control, but also effectively reduce fatigue load of key components. LQG controller has better performance than conventional PI controller, dynamic load Optimization is more effectively, more suitable for large-scale wind turbine pitch control.关键词
