Construction of Simulation Model of 'Lushijia No.1' under Wind and Wave Integration

Abstract

Based on the new ' Lu Shijia No.1 ' platform, the project team has customized a set of force and motion response theory system for it. The existing model is extended, and the basic coordinate system of eight frames is proposed for the new platform, which simplifies the analysis process. By considering the design parameters of the platform, the linear potential flow theory, Stokes wave theory and blade element theory are used to analyze the force and motion response of the platform, and the numerical calculation standards of various forces are defined. At the same time, the H ∞ controller of the optimized fan is integrated to improve the overall control system of the fan. Based on the full coupling integration of wind turbine and platform, the project team uses AQWA hydrodynamic analysis software to simulate and analyze the platform in frequency domain. With the help of FAST-matlab, the time domain full coupling analysis of the platform is carried out. The simulation results show that the new ' Lu Shijia No.1 ' achieves the expected effect of ' reducing response and increasing power '. On the basis of simulation, the project team constructed a scaled down ' Lu Shijia No.1 ' model. Through the final launching test of the solid model, the feasibility of the theoretical design was proved.
