Individual pitch control on wind turbines with permanent magnet synchronous generator for reduction of mechanical load and stability of output power

Bu makalede rüzgâr türbinlerinin çıkış gücü kalitesinin arttırılması ve türbin üzerindeki mekanik yüklerin hafifletilmesi üzerine bir çalışma yapılmıştır. Nominal rüzgâr hızlarının üzerinde kanat hatve açısı ayarlanarak rüzgâr türbininin çıkış gücü nominal değerde tutulmuştur. Ayrıca bireysel hatve açısı kontrolü ile de rüzgâr türbini üzerindeki mekanik yükler azaltılmıştır. Kalıcı mıknatıslı senkron jeneratör kullanılan rüzgâr türbini Matlab/Simulink’de modellenmiştir. Simülasyon sonuçları, bireysel hatve açısı kontrolü ile rüzgâr türbininin hem çıkış gücü kalitesinin sağlandığını hem de rüzgâr türbini üzerindeki dengeli periyodik yüklerin azaltıldığını göstermiştir. In this article, increasing output power quality of wind turbines and decreasing mechanical loads on turbines was studied. By adjusting the blade pitch angle on nominal wind speed, output power of wind turbine kept on nominal value. Beside, by individual pitch angle control, mechanical loads on wind turbine was decreased. Wind turbine in which permanent magnet synchronous generator is used, modeled in matlab/simulink. Simulation results show that by individual pitch angle control both output power quality of wind turbine assured and balanced periodical loads on wind turbine reduced.
