This paper takes a kind of nautilus isometric spiral wind turbine as prototype, and by analysing the structural and aerodynamic performance of this wind turbine, three wind deflectors with different structures are designed. The torque characteristic and wake characteristic of the wind turbine are analysed by simulation method and the influence of three different structures of wind deflector on the performance of wind turbine is compared. The results indicate that the performance of the wind

Finally, according to the wake characteristic of wind turbine, the reasonable spacing of the wind turbine cluster operation was analysed, the vertical arrangement and horizontal arrangements are designed, and the reliability of the arrangement is verified.
