摘 要：Due to the lack of rigid support structure of floating wind turbine（WT） at sea, the external load affected by wind-wave-flow coupling is much larger than that of fixed-pile WT. How to make the floating WT safe, reliable and stable operation has become a research hotspot in the current far-reaching sea breeze energy utilization. In order to reduce the load of offshore floating WT subjected to external environment during operation, this paper studies a double damper load reduction structure with confined mass dampers installed in the nacelle and floating platform. Active control method to reduce the load of floating WT at sea. Through the simulation verification analysis of NREL 5 MW wind turbine, it is found that the load impact and output power stability are effectively improved, which provides a useful method for the development of deep sea wind power resources in China.
