abstract

Wind turbine design for low wind regimes is gaining importance as existing high wind sites are heavily utilized. Maximizing energy yield from a low wind regime while adhering to load constraints is the biggest challenge. Longer rotors and higher towers are currently being used to maximize energy capture and improve AEP. The focus of this work is to assess new blade planforms for low wind speed blade design. Planforms with maple shape are studied and a new design methodology based on lift force distribution is adopted. CFD analysis is carried out for the blade planforms to validate the design methodology and the results show similar performance trends as that of the conventional design method.
