|
摘要
海上风力发电机主要安装在离岸式浮式基础上,浮式基础的稳定性很大程度影响到风力发电机的运行效果以及发电设备的安全运行。基于自回归模型(AR)法,对海上风力发电机上的风载荷进行分析模拟;基于线性微幅波理论,对浮式基础上的垂荡、纵摇和纵荡波浪激励力进行分析模拟;采用有限元软件分析了浮式风力发电系统在风波耦合作用下的动力响应,并将仿真中所得的结果与马休稳定性图谱进行验证得出浮式基础的稳定性,为浮式基础的设计与稳定性分析提供建议。
Offshore wind turbine is mainly installed on offshore floating foundation. The stability of floating foundation greatly affects the operation effect of wind turbine and the safe operation of power generation equipment. Based on the auto-regressive model(AR) method,the wind load on the offshore wind turbine is analyzed and simulated, and the heave, pitch and heave wave forces on the floating foundation are analyzed and simulated based on the linear micro-wave theory. The finite element software is used to analyze the dynamic response of the floating wind power generation system under the coupling action of wind and waves, and the simulation results are verified with the Mathew stability graph, and the stability of floating foundation is obtained. Some suggestions are provided for the design and stability analysis of floating foundation.
