机械系统状态空间法在风力发电机主轴系统上的应用

The Application of State-Space Model for Mechanical System to the Main-shaft System of Wind Turbine

应用结构动力学和现代控制理论,把风力发电机组低速轴考虑为柔性轴,把高速轴考虑为刚性轴,建立了风力发电机组主轴系统的状态空间模型,并对其仿真分析,确定了抑制主轴系统振动的途径。

The state-space model of the main shaft system in wind turbine was built up for the simulation analysis,based on the structure dynamics and modern control theory,while assuming low-speed shaft to be flexible one and assuming high-speed shaft to be rigid one. Finally, the method was confirmed to restrain the vibration of the main shaft system.
