In order to improve the power generation efficiency of wind farms within the limited land resources and reduce the impact of the upper fan on the wake of the lower fan. By using the Windcube V2 Doppler wind gauge method, the wake changes of the two fans in the staggered arrangement state were used to investigate to study the influence of the wind wake field and no the wind wake field between the two fans, which was compared and analyzed. The results show that the wake of the has the greatest influence on the second quadrant of the lower fan. The axial velocity first decreases then increases and again decreases then increases and the first quadrant region first decreases and then increases. The radial and tangential velocity amplitudes and frequencies appear first increase and then decrease. The radial velocity amplitude and frequency are the largest at the 5D section, and the 3D is the smallest. The tangential velocity amplitude and the frequency are the largest at the 5D section, and the 8D is the smallest. It is concluded that the upper fan forms a complex turbulence phenomenon on the wake of the lower fan, and the turbulence intensity promotes the integration of the internal and external flow fields of the wake, thus causing the difference between different velocity values.
