The multiple controlled fan wind tunnel is designed to investigate the typhoon wind load and improve the resistance ability for complex buildings and transmission tower-line systems (TTLS). In order to achieve the key technology during the structure design of the full-scale wind tunnel, a small-scale model of the closed-circuit single controlled fan wind tunnel is established. The uniform and turbulence characteristics of the atmospheric boundary layer (ABL) in the small-scale wind tunnel are discussed. The obtained results show that the value of the maximum average wind speed can reach 18.2 m/s and the maximum circular frequency is 7 Hz. Meanwhile, the mean wind speed of the sinusoidal wave flow is 15.1 m/s at the peak of amplitude of 3.8 m/s. The generated sinusoidal wave flow has a high correlation coefficient at 94.3% with the target.
