Simulation method of semi-physical wind power generation based on combined wind speed and tip speed ratio

In order to research wind power generation technology in the laboratory, a feasible scheme based on modeling and simulation was proposed to simulate wind turbines operating characteristics. The characteristics of wind turbine and the method of optimum leaf tip speed ratio are analyzed, the wind turbine simulation model is constructed, the wind speed model combined with four wind speeds characteristics is established to simulate natural wind speed, and the semi-physical wind power simulation system is built by combining software and hardware. The correctness of the program is verified through simulation experiments of the wind turbine operation state under instantaneous wind speed and natural wind speed, which can accurately reflect the operating characteristics of the wind turbine under the actual wind speed, and provide a reference for the future research of wind power technology.

I. Introduction

Wind power is clean and renewable, with good economic and social benefits. However, the efficiency of the wind power system is greatly affected by wind energy resources and equipment parameters in the environment, the rational design of wind speed parameters and equipment parameters is of great importance to the conversion of wind energy into electrical energy [1]. Due to factors such as rapid changes in the natural wind field that are difficult to measure and repeated experiments, it is difficult to conduct on-site wind power generation experiments [2]. However, the simulation technology is not restricted by the environment and weather conditions. It has been gradually applied in the research and experiment of wind power [3].
