Transformatörlerde iç arıza akımlarının benzeşimi

Bu çalışmada, güç transformatörlerinin iç kısa devre akımlarının modellenmesi ve bilgisayar destekli benzetimi gerçekleştirilmiştir. Güç transformatörü sarım – sarım ve sarım – toprak arızalarının benzetimi bu çalışmanın ana öğesini oluşturmaktır. İç arızalarının ayrıntılı matematiksel modeli iletim hattı modeli (İHM) kullanılarak çıkartılmıştır ve giriş büyüklükleri arasındaki işlevsel ilişkiler ortaya konmuştur. Bu çalışmada ortaya konan bilgisayar destekli benzetimler, sarım – sarım ve sarım – toprak arızaları için İHM tekniğinin Matlab ™ uygulamalarından meydana gelmektedir. Benzetimlerde kullanılan devre parametreleri laboratuar ortamında gerçekleştirilen gerçek zamanlı deneylerle desteklenmektedir.

Simulation of transformer internal faults

This paper is based on the techniques of modeling and simulating transformer internal faults. The modeling of turn to turn and turn to earth fault is objective of this study. The detailed mathematical formulation of internal faults is developed by using Transmission Line Method (TLM). Matlab ™ is used for modeling turn to turn and turn to earth faults by using TLM technique. Circuit parameters used the modeling are supported by the real time laboratory studies.
