OPTIMAL DESIGN OF WIND TURBINE BLADES EQUIPPED WITH FLAPS

摘要: As a result of the significant growth wind turbines in size, blade load control has become main challenge for large turbines. Many advanced techniques have been investigated aiming at developing devices to ease loading. Amongst them, trailing edge flaps proven as effective alleviation. The present study aims investigating potential benefits enhancing energy capture capabilities rather than A software tool is especially developed aerodynamic simulation utilising blades equipped with flaps. part these turbines, system must be also simulated. carried out via solving an optimisation problem which gives best value controlling parameter each turbine run condition. Developing genetic algorithm designed and integrating it performance evaluator, design constructed. employed carry case studies. results studies on AWT-27 (Aerodynamic Wind Turbine-27) reveal that, expected, location flap key influencing amount improvement power extraction. placing about 70% span from root blade. size effect enhancement average power. This effect, however, reduces dramatically increases. For constant speed rotors, adding without re-designing topology can improve extraction capability high 5%. However, pretwist overall reached 12%.
