摘要:
对某个风电场的23座高桩-混凝土承台式海上风电塔进行了1年的强振监测,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,有时振动加速度可超过10 m/s2,每个月多达几百次;在某次台风作用下,塔筒的振动加速度接近10 m/s2;施工船靠船时的碰撞引起塔筒的强振幅值接近15 m/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:高桩-混凝土承台式风电塔在台风、机舱偏航,施工船碰撞时都会产生强烈振动。因此,机舱偏航和施工船碰撞引起风电塔的强振现象过于频繁发生,是风电塔疲劳损伤的重要因素。本文的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:
One year of strong vibration monitoring of 23 high-pile-concrete bearing offshore wind power towers of a wind farm was performed, and its strong vibration characteristics under typhoon and yaw impact were counted.Analysis of the monitoring data found that the yaw of the nacelle against the wind will cause strong vibration of the tower, and this type of strong vibration phenomenon lasts for tens of seconds, and sometimes the vibration acceleration can exceed 10 m/s2, up to several hundred times per month;Under a typhoon, the vibration acceleration of the tower is close to 10 m/s2;the strong amplitude of the tower tube caused by the collision of the construction ship when approaching the ship was close to 15 m/s2;by analyzing the natural frequency value of the tower tube during the 1-year operation of the wind power tower, it was found that the natural frequency value and damping ratio of the first 3 orders were not changed.The monitoring results show that high-pile-concrete bearing wind turbine towers yaw during typhoon and engine room, and strong vibration will occur when the construction ship collides.Therefore, the strong vibration of the wind power tower caused by the yaw of the nacelle and the collision of the construction ship occurs too frequently, which is an important factor for the fatigue damage of the wind power tower. 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.
