Simulation of the atmospheric boundary layer is the key of wind resource assessment. However, there is a widespread lack of consideration of actual meteorological factors in the existing atmospheric boundary layer simulation research, which leads to the problem of insufficient accuracy. To this end, this paper develops a set of atmospheric boundary layer simulation methods for wind farms by combining actual wind measurement data and open-source computational fluid dynamics software. By analyzing and processing wind measurement data, the method incorporates two key factors, surface roughness and atmospheric stability, into the simulation of the atmospheric boundary layer, so that it can simulate the flow field in the bound-ary layer more realistically. The method is used to simulate a real case and compare it with the measured data of the wind tower to verify the reliability of the developed method. The results show that the simulation results of the developed method under different atmospheric stability levels are in good agreement with the measured data. Compared with the existing commercial software, the calculation accuracy is greatly improved, and it has certain engineering practical value.
