摘要
由于海上风力发电机组的外界载荷条件比陆地上的风力发电机组更加复杂,因此在机组设计中要考虑到海上风机载荷条件.在研究海波性能和运动规律的基础上,给出了海水中的塔架载荷的计算公式;针对海上风力发电机组的结构特点,将研究的海波载荷计算方法用于风机的塔架载荷计算,以1.0 MW风力发电机组为例,对塔架所承受的海波载荷和风载荷进行了计算,经过对比分析可知,风载荷大于海波载荷并为同一数量级的载荷,因此,在设计中更应注意这两种载荷的耦合作用.
The load condition of offshore wind turbine is more complicated than that on land, and must be considered in design. In view of the wave feature and its moving rule, the formulas of tower loads on offshore wind turbines were presented. Based on the structure feature of offshore wind turbines, the computation method of the wave loads was applied to calculate the tower loads. The wave loads and wind loads of 1.0 MW wind turbine on tower were obtained. By means of analysis and contrast, it is concluded that wind loads are heavier than wave loads, but both are in same order. Therefore, the coupling action between two loads should be paid a more attention in design.
