摘要：

This study investigates the impact of integrating a guide ring upstream of the rotor plane for performance increase of a horizontal axis wind turbine rotor. The guide ring is strategically positioned near the rotor hub to reduce the radial component of wind flow and retain more axial velocity through the rotor. The methodology involved physical testing of a rotor retrofitted with guide rings ranging from 15% to 20% of the rotor diameter. Comparative experimental results demonstrate an increase in peak performance for retrofitted rotors, when compared to a standard rotor. The rotor retrofitted with an 18% guide ring emerged as the most beneficial choice, exhibiting a 4.34% peak power output increase and a broader operational range than the standard rotor. Overall, the study contributes valuable insights into post-installation optimisation strategies for horizontal axis wind turbine rotors.
