GÜÇ SİSTEMLERİNDE FACTS UYGULAMALARI

Artan enerji talebi, yeni hatların yapılmasındaki kısıtlamalar ve geleneksel kompanzasyon cihazlarının dezavantajları gibi birçok sebepten dolayı, mevcut enerji iletim sistemlerinin verimliliğinin maksimuma çıkarılması zorunlu hale gelmiştir. Mevcut enerji iletim sistemlerinin kullanımını maksimize etmek için mümkün olan seçenekler analiz edildiğinde, yüksek seviyeli güvenilirlik ve kararlılık ile güç elektroniği çözüm olarak görünmektedir. Güç elektroniği teknolojisinin hızlı gelişimi, güç sistemlerinin kontrolü için yeni bir teknoloji olan, Esnek Alternatif Akım İletim Sistemleri (FACTS, Flexible Alternating Current Transmission Systems) teknolojisinin gelişmesine olanak tanımıştır. Bu çalışmada geleneksel tristör tabanlı FACTS cihazları ve konverter tabanlı FACTS cihazları devre konfigürasyonları, güç sistemine etkileri ve kullanım amaçlarına karşın karşılaştırılmış ve incelenmiştir. Ayrıca Türkiye ve Dünyadaki FACTS uygulamalarından örnekler verilmiştir.

FACTS APPLICATIONS IN POWER SYSTEMS

Due to many reasons such as, an increasing demand for energy, the constraints in the building of new transmission lines and the disadvantages of the conventional compensation devices, it has been necessary to maximize the efficiency of existing energy transmission systems. The analysis of the choices available for maximizing the existing energy transmission systems, solution has seen as the power electronics with high level of trustability and stability. The rapid development of the power electronics technology makes it possible the development of a new technology for the control of the power systems, called “Flexible Alternating Current Transmission Systems (FACTS)”. In this study conventional thyristor based FACTS devices and converter based FACTS devices are investigated and compared against their configurations, their effects and aim of usage on power systems. In addition example of FACTS applications in real World are presented.

Keywords:

FACTS, Thyristor based FACTS, Converter based FACTS, Power systems.,
