“…The research results of Takanori et al [21][22][23][24][25][26] show that the wake velocity distribution of NREL-5MW [27] wind turbine is quite different in the X, Y, and Z axes. The dot matrix arrangement scheme can form the mutual restriction between the six wind turbines, effectively balance the wind tilt moment between the wind turbines, and generate greater waterline inertia moment to balance the wind tilt moment, to reduce the pitching motion.…”

The new lattice floating wind turbine integrated system (also known as Dot Matrix Floating wind turbine, and hereinafter referred to as DMF) is proposed as a new concept. It is a design scheme that combines multiple wind turbines into a polygonal floating foundation in the form of a lattice arrangement, which can meet the research and development requirements of higher power generation equipment in the future. More far-reaching, it has obvious advantages over the traditional floating wind turbine scheme in terms of structural cost and motion stability, which provides a new idea for the development of offshore wind power energy. Firstly, the structural parameters and mechanical model of DMF are analyzed to determine the feasibility and superiority of the overall scheme of the new lattice foundation. Combined with the traditional OC4 semi-submersible wind turbine system, the hydrodynamic simulation under wind, wave, and current load is carried out, and the hydrodynamic response law of DMF under the different environmental factors is summarized and analyzed. It is concluded that the stability of DMF in pitching motion is 70% higher than that of traditional OC4 system. In order to further verify the feasibility of the DMF system and the accuracy of the theoretical model, based on the similarity theory, this study carried out the small-scale prototype processing of DMF and the simulation experiment of wind wave flume. The test results are in good agreement with the simulation data. Finally, aiming at the problem of the large amplitude of swaying motion response of DMF in the simulation results, a mooring optimization scheme suitable for the new DMF is proposed, which provides 47% stability compared with the traditional catenary mooring through comparative analysis. This study provides a reference and theoretical basis for the research and development of offshore multi-wind turbine combined equipment and hydrodynamic stability optimization. It has certain theoretical guiding significance and economic development value.

“…The distribution of wind turbine wake is an important factor affecting the overall power generation and efficiency, and it is also an important reference for the arrangement spacing of multiple wind turbines. The research results of Takanori et al [22][23][24][25][26][27] show that the wake velocity distribution of NREL-5 MW [21] wind turbine is quite different in the X, Y, and Z axes. Specifically, when the distance between wind turbines is less than 1D, the loss of wake velocity in the X, Y, and Z axes is about 50%, which will not be studied in this paper.…”
