实际风电场的高强度湍流风将加剧垂直轴风力机气动复杂性，显著影响风能利用率。为此，利用吸气控制改善湍流风下垂直轴风力机气动性能，并采用CFD方法研究了垂直轴风力机气动及流场特性，通过对比吸气控制前后垂直轴风力机在定常风与湍流风下的能量利用系数、转矩变化及流场特性，探讨吸气控制对垂直轴风力机气动性能的影响。结果表明：湍流风加剧了翼型流动分离，宽尖速比范围内降低了整机风能利用率及转矩稳定性；增加吸气控制可有效改善湍流风下风力机气动性能，提高风轮转矩，从而提升风能利用率，并降低整机风能利用率波动；吸气控制可改善湍流风下风力机尾迹特性，风轮流场特性及翼型表面流动特性，并使各尖速比区间风力机输出效率提升，其提升效果最佳可达49.92％。

The high-intensity turbulent wind of the actual wind farm aggravates the aerodynamic complexity of the VAWT and significantly affects the wind energy utilization rate. Therefore, suction control is used to improve the aerodynamic performance of VAWT under turbulent wind. The aerodynamic and flow field characteristics of VAWT are studied by CFD method. The influence of suction control on the aerodynamic performance of VAWT is discussed by comparing the energy utilization coefficient, torque change and flow field characteristics under steady wind and turbulent wind with and without suction control.The results show that the turbulent wind intensifies the flow separation of the airfoil. It reduces the wind energy utilization and torque stability in the wide TSR range. Increasing the suction control can effectively improve the aerodynamic performance of the wind turbine under turbulent wind and increase the torque of the VAWT, thereby improving the utilization rate of wind energy. In addition, it also reduces the fluctuation of the wind energy utilization rate. The suction control can improve the wake characteristics , flow field characteristics and the flow characteristics of the airfoil surface under turbulent wind, and improve the output efficiency of the wind turbine in each TSR range, and the best improvement effect can reach 49.92 %.
