It is difficult to evaluate the wind turbine performance on a complex terrain. Turbulence and vortex caused by the terrain factor, as the reason. Numerical site calibration (NSC) is expected as the method to evaluate the wind turbine performance on a complex terrain, because standard site calibration can't apply to these sites. NSC depends on the wind prediction method and simulation code, so these applicable to the complex terrain are required. To establish NSC, some researchers discuss the requirements such as the characteristic of each numerical simulation method, the computational domain size, the boundary condition. This paper describes the effect of the computational domain size to investigate the suitable conditions for NSC. Calculations with the large-eddy simulation (LES) model, MSSG-A, are presented for the atmospheric flow on a site.
