Yenilikçi Uyarlanabilir Bir Zarf Koruma Sisteminin Farklı Rüzgar Türbinleri Üzerindeki Etkinliğinin İncelenmesi

Bu çalışmada, rüzgar elektrik santrallerinde yaygın olarak kullanılan yatay eksenli rüzgar türbinlerini aşırı yüklenmelerden korumak için geliştirilen yenilikçi uyarlanabilir bir zarf koruma sistemi kısaca açıklanmıştır. Türbinlere ve türbin çalışmasındaki değişikliklere uyarlanabilen yenilikçi sistem, rüzgar ve türbine ait durum değişkenlerini gerçek zamanlı olarak izlemektedir. Bu sayede, türbinin tehlikeli çalışması durumunu önceden sezmekte ve sadece gerektiğinde türbini korumak için türbin kanat yunuslama açısı kontrol sistemine müdahele etmektedir. Sistem tasarımı, rüzgar türbinlerini aşırı itki kuvvetinden koruyacak şekilde gerçekleştirilmiş olup bu çalışmada farklı kanat sayıları ve rotor çaplarındaki Türbin A, Türbin B ve Türbin C olarak adlandırılan rüzgar türbinleri üzerindeki etkinliği simülasyonlar ile incelenmiştir. Simülasyon sonuçları, yeni zarf koruma sisteminin değişik rüzgar türbinlerine uyarlanabildiği ve türbin kanatlarının yunuslama açılarını topluca değiştirerek türbinleri önceden belirlenen itki kuvveti sınır değerleri içinde çalıştırarak koruyabileceğini göstermiştir.

Investigation of the Efficacy of a New Envelope Protection System on Different Wind Turbines

This paper briefly defines an adaptive envelope protection system, which is developed to protect the commonly used horizontal axis wind turbines in wind farms from excessive loads. The system, which can adapt to turbines and their operations, follows up wind and turbine variables. Thus, in advance, it detects the cases of excessive loads, and only when required, it interacts with the turbine blade pitch control system for turbine protection. The system is designed such that it protects turbines from high thrust forces. Here, the efficacy of the system is investigated through simulations on different horizontal axis turbines, referred to as Turbine A, Turbine B, and Turbine C with different number of blades and rotor diameters. Simulation results demonstrate that the protection system is highly effective in adaptation to various turbines and through changing the blade pitch angles, collectively, it protects them by operating within pre-defined thrust limits.
