TMD控制对15 MW单桩风力机地震动力响应的影响
Influence of TMD control on dynamic responses of a 15 MW monopile offshore wind turbine
摘要
Abstract
Offshore wind turbines installed close to earthquake-prone zones are not only affected by wind and wave loadings,but also threatened by earthquakes.In order to reduce the earthquake impacts on the structural vibration and load of large-scale wind turbines,a seismic coupled analysis and structural control architecture has been developed by improving FAST based on the modal acceleration method and the Tuned Mass Damper(TMD).The control effects of TMD on tower vibration and load reduction of the IE A 15 MW monopile wind turbine due to different ground motions are investigated.The results show that the TMD can significantly reduce the tower-top displacement and tower-base load for each examined ground motion.The best effect on alleviating tower-top vibration is achieved when the tuning frequency ratio of the TMD is 0.9,reducing the tower top displacement by 89.8％.The fluctuation amplitude of tower-base bending moment following the earthquake event is significantly reduced by the TMD with a tuning frequency ratio of 0.8 that is capable of reducing the standard deviation by up to 99％.关键词
