Description
technical field [0001] The invention relates to the field of offshore wind power generators, in particular to a vibration characteristic test system for wind and wave combined action offshore wind power generators. Background technique [0002] my country's offshore wind resources are abundant. Compared with inland wind farms, offshore wind farms have the advantages of high wind speed, stable ocean style, and flat sea surface. They will surely become an important source of energy for the sustainable development of my country's eastern coastal areas. However, offshore wind power has its own special technical difficulties. Offshore wind turbines are subject to the combined effects of wind and wave forces at the same time, resulting in the complexity of the wind turbine's air and wave dynamic response, which in turn affects the stable performance of offshore wind turbines and has a negative impact on the operation of offshore wind turbines. The grid connection of wind power and...
