Abstract



Güç
sistemlerinin pahalı donanımlarından olan transformatörlerin izlenmesi son
yılların önemli konularından biridir. Transformatör izleme sistemleri
genellikle arızaların tespiti, transformatör ömrünün belirlenmesi, kayıpların
ölçümü ve sargı sıcaklıklarının belirlenmesi amacıyla kullanılır. İzlemede
kullanılan önemli parametrelerden biri transformatör sargı direncidir. Bu
yüzden, bu çalışmada yeni bir sargı direnci izleme yöntemi sunulmuştur. Yöntem
transformatörlerin eşdeğer devresi ve güç eşitlikleri kullanılarak geliştirilmiştir.
Hesaplamalarda transformatörlerin primer ve sekonder tarafı akım ve gerilim
değerleri kullanılmaktadır. Böylece transformatörlerin ortalama sargı
direncinin gerçek zamanlı izlenmesi sağlanmaktadır. Yöntem tek fazlı
transformatörlere uygulanabildiği gibi yıldız-yıldız ve üçgen-yıldız bağlı
transformatörler için de kullanılabilmektedir. Bu çalışmada, öncelikle yöntemin
matematiksel işlem adımları verilmiştir. Sonrasında Matlab ortamında yapılan
benzetim çalışmaları ve iki farklı transformatör üzerinde gerçekleştirilen
deneysel çalışmalar verilmiştir. Benzetimler ve deneysel çalışmalar yöntemin
geçerliliğini açık bir biçimde ortaya koymuştur.
