摘要:
对某座风电场的70座单桩式海上风电塔基础振动及其中7座的塔筒进行了1年的振动监测,统计了其在台风、偏航冲击等作用力下的强振特性。监测数据分析发现：机舱对风向偏航时会引起塔筒强烈振动,且此类型强振现象持续时间达几十秒,有时塔筒顶部的振动加速度达到14m/s2、基础振动加速度达到3.5m/s2;在台风作用下,塔筒的振动加速度值达到12.5m/s2、基础振动加速度值达到4.5m/s2;通过分析风电塔1年运营期间的塔筒固有频率值,发现前3阶固有频率值、阻尼比未发现变化。监测结果表明：单桩式风电塔在台风、机舱偏航时都会产生强烈振动。机舱偏航引起风电塔的强振现象过于频繁发生,可能会引起风电塔出现振动疲劳,应引起重视。研究成果可为此类型风电塔设计、运营安全监测及损伤诊断提供参考。
Abstract:
The paper conducts the vibration monitoring for the foundation vibration of 70 mono-pile offshore wind power towers and 7 of the towers on a wind farm for one year,and calculates their strong vibration characteristics under the action of typhoon, yaw impact,etc. Monitoring data analysis shows that:the yaw of the nacelle against the wind direction will cause strong tower vibration,and this type of strong vibration lasts for tens of seconds,sometimes the vibration acceleration at the top of the tower reaches 14 m/s2,and the basic vibration acceleration is close to 3.5 m/s2;under the action of the typhoon,the vibration acceleration value of the tower is close to 12.5 m/s2,and the vibration acceleration value of the foundation is close to 4.5 m/s2;by analyzing the natural frequency value of the tower tube during the one-year operation of the wind power tower,it is found that the natural frequency values and damping ratio of the first 3 orders have not changed.The monitoring results show that the single-pile wind power tower will generate strong vibration during typhoons and yaw impact. The strong vibration of the wind power tower caused by the nacelle yaw occurs too frequently,which may cause vibration fatigue of the wind power tower,which should be paid attention to. The research results of this paper can provide reference for the design,operation safety monitoring and damage diagnosis of this type of wind power tower.
