Modifiye PSO ile deðiþken hýzlý rüzgar türbini kanat açýsýnýn ayarlanmasý

Bu çalýþmanýn ana motivasyonu, rüzgar türbinlerinin (RT) mekanik çýkýþ gücüne etki eden kanat açýsýnýn (β) parçacýk sürü optimizasyonu (PSO) ile ayarlanmasýdýr. Bu amaca yönelik olarak, standart yapýdaki PSO modifiye edilmiþtir. Böylece modifiye edilmiþ PSO algoritmasý rüzgar hýzýnýn deðiþimine baðlý olarak kendini güncelleyebilen bir duruma getirilmiþtir. Yapýlan çalýþma da, deðiþken rüzgar hýzlarýnda çalýþan rüzgar türbinlerinin kanat açýlarýnýn kontrolü sürü zekasýna dayalý bir optimizasyon algoritmasý kullanýlarak ayarlanmasý saðlanmýþtýr. Çalýþma kapsamýnda deðiþen hýzlý rüzgar türbinini iki farklý þekilde benzetim ortamýnda çalýþtýrýlmýþtýr. Birinci durumda kanat açýsý sabit tutularak (β=0° için) deðerler elde edilmiþtir. Ýkinci durumda ise önerilen modifiye PSO’un ürettiði açý ile kanat açýsý ayarlanarak çalýþtýrýlmýþtýr ve her iki durumun sonuçlarý tartýþýlmýþtýr.

Adjustment of variable speed wind turbine blade angle with Modified PSO

The main motivation of this study is to adjust the blade angle (β), which affects the mechanical output power of wind turbines (WTs), by particle swarm optimization (PSO). For this purpose, the standard PSO structure has been modified. Thus, the modified PSO algorithm has become capable of updating itself depending on the change of wind speed. In the study, the blade angles of wind turbines operating at variable wind speeds were controlled and adjusted using an optimization algorithm based on swarm intelligence. Within the scope of the study, a variable speed wind turbine was operated in two different simulation environments. In the first case, the values were obtained by keeping the wing angle constant (for β=0°). In the second case, the proposed modification was operated by adjusting the blade angle with the angle produced by PSO, and the results of both cases were discussed.
