Güç sistemlerinde meydana gelen kısa devre arızalarına karşı akım sınırlayıcı yapısının en uygun yerleşim yerinin belirlenmesi

Güç sistemlerinde meydana gelen simetrik ve simetrik olmayan kısa devre arızaları şebekenin güç dengesini bozarak güç sistemini kararsız hale getirebilmektedir. Bu durumun önüne geçmek ve sistemin kararlı halde kalma yeteneğini geliştirmek için çeşitli arıza akımı sınırlayıcı yapıları, özellikle yenilenebilir enerji kaynakları içeren güç sistemlerinde sıkılıkla kullanılmaktadır. Nitekim, bu çalışmada, güç sistemlerinde meydana gelen kısa devre arızalarına karşı süperiletken arıza akımı sınırlayıcı (SAAS) yapısının en uygun yerleşim yeri bulunmaya çalışılmıştır. Güç sistemi modeli olarak 3 makinalı, 9 baralı batı sistemi koordinasyon konseyi (WSCC) test sistemi kullanılmış ve analizler MATLAB’da gerçekleştirilmiştir.

Determination of optimal placement of fault current limiting device against short circuit faults occur in power systems

Symmetrical and unsymmetrical short circuit faults occur in power systems may make the power system unstable by disrupting the power balance of grid. To prevent this situation and improve the ability of power system to remain stable, kind of fault current limiting devices are used in power systems include renewable energy sources especially. Thus, in this study, it is aimed to find optimal placement of superconducting fault current limiter (SFCL) in a power system against the short circuit faults. Western system coordinating council (WSCC) 3 machine, 9 bus test system is used as power system model for this study and analyses are performed in MATLAB software.
