Resistive Fault Current Limiter Design and Realization of Prototype

Öz

Today, there is a significant increase in electricity consumption with population growth, expansion of residential areas and industrial areas, and the development of technology. Parallel to this, with the increase in production capacity, high current levels caused by faults in the system for various reasons create dangerous situations for the system and the elements in the system. Limitation of fault currents provides protection of the system and system elements from the compelling thermal, dynamic and electromagnetic effects of these currents. In this study, the structure and working principle of Resistive Superconducting Fault Current Limiters (R-SFCL), which is one of the modern fault current limiting methods, are investigated. In addition, the real data obtained by performing the R-SFCL design in the laboratory environment and performing the faults in the created experimental system, and the simulation results performed with MATLAB/Simulink are compared.

Rezistif Süperiletken Arıza Akımı Sınırlayıcı MATLAB-Simulink Modeli ve Uygulaması

Öz

Günümüzde, nüfus artışı, yerleşim yerlerinin ve endüstriyel alanların genişlemesi ve teknolojinin gelişmesiyle birlikte elektrik tüketiminde önemli bir artış görülmektedir. Buna paralel olarak üretim kapasitelerinin de artması ile elektrik güç sistemlerinde çeşitli sebeplerle meydana gelen arızaların sebep olduğu yüksek akım seviyeleri, sistemdeki elemanlar için tehlikeli durumlar oluşturmaktadır. Arıza akımlarının sınırlandırılması, bu akımların zorlayıcı termal, dinamik ve elektromanyetik etkilerinden sistemin ve sistem elemanlarının korunmasını sağlar. Bu çalışmada, modern arıza akımı sınırlandırma yöntemlerinden biri olan Rezistif Süperiletken Arıza Akımı Sınırlayıcıların (R-SFCL) yapısı ve çalışma prensibi incelenmiştir. Ayrıca, bir R-SFCL tasarımı yapılmış ve oluşturulan deney sisteminde arızalar gerçekleştirilerek elde edilen gerçek veriler ile MATLAB/Simulink’de gerçekleştirilen simülasyon sonuçları karşılaştırılmıştır.
