Wind turbine wake flow velocity and turbulence intensity prediction method considering atmospheric stability

The invention discloses a wind turbine wake flow speed and turbulence intensity prediction method considering atmospheric stability. The method comprises the following steps: acquiring inlet wind resource information and wind turbine generator characteristic parameters; based on the inflow wind resource information and the characteristic parameters of the wind turbine generator, the wake flow radius rw (x) of the wind turbine wake flow area flowing to any section position under different stability conditions is calculated, and the wake flow influence range is determined; a wind shear effect under the influence of an atmospheric stability factor is considered, and an initial flow velocity distribution profile U0 (z) and a turbulence intensity distribution profile I0 (z) of the inlet wind are calculated; based on the bimodal distribution function, the speed Uw (x, y, z) of any position of the wind turbine wake flow area under different stability conditions is calculated; and the turbulence intensity Iw (x, y, z
