Load-frequency control in two area power system

Bu makalede, bölge yük-frekans kontrolü için bir bulanık mantık uygulaması araştırılmıştır. Kontrolör, iki bölgeli enterkonnekte güç sistemi için dizayn edilmiştir. Kontrolörde bulunan integral ve oransal kazanç katsayıları için farklı değerler kullanılarak sistemin dinamik performansı arttırılmıştır. Geleneksel PI kontrolör ile önerilen kontrolör arasında yapılan karşılaştırma sonucunda, sistemin basamak yük değişimi dinamik tepkisine önerilen kontrolörün en iyi sonucu verdiği gözlenmiştir.

İki bölgeli güç sistemlerinde yük-frekans kontrölü

This paper presents a fuzzy application to the area of load frequency control (LFC). The study has been designed for a two-area interconnected power system. Using variable values for proportional and integral gains in the controller units the dynamic performance of the system is improved. The comparison between a conventional PI controller and the proposed controller shows that the proposed controller can genarate the best dynamic response following a step load change.
