基于输入-状态联合估计的漂浮式风机塔架结构载荷反演及状态分析
Structural load inversion and state analysis of floating wind turbine tower based on joint input-state estimation
摘要
Abstract
[Objective]This study uses the structural load inversion method to conduct a dynamic response state analysis of a floating wind turbine tower under wave action.[Method]Based on a semi-submersible wind turbine,the measurement data is simulated in the time domain,and the mass-normalized modes of the tower are calculated using a frequency-domain simulation model of the floating wind turbine.Both are used as inputs to a joint input-state estimation(JIS)algorithm to conduct the structural load inversion and real-time state analysis of the floating wind turbine tower.[Results]The results show that when using the simulated data of tower nodes as inputs to the JIS algorithm,the estimated tower root loads and node responses agree well with the simulated results,achieving high-precision inversion.[Conclusion]The inversion results veri-fy that the JIS algorithm is effective and can be used for the real-time state analysis of floating wind turbines to ensure their long-term safe and stable operation.关键词
