Güç sistemlerinin çalışması esnasında bazı nedenlerden dolayı kararsızlık problemleri ile karşı karşıya kalmaktadır. Kararsızlık problemlerinin en önemli nedenlerinden birisi kısa devre durumlarıdır. Kısa devre güç sistemlerinde salınımlara sebep olmaktadır. Bu salınımları ortadan kaldırmak için Güç Salınım Sönümleme Kontrolü (GSSC) kullanılmaktadır. Bu çalışmada, güç sistemlerinde osilasyonların sönümlenmesi için Kundur 4 makinalı sistemde farklı senaryolar ile analizler gerçekleştirilmiştir. Ayrıca çok makinalı sistemde kullanılan senkron generatörlerin alt-geçici durum dinamik modellemeleri bu çalışmada tercih edilmiştir. Birleştirilmiş Güç Akışı Kontrolü (UPFC), GSSC ve alt-geçici durum dinamik modellemelerinin kullanıldığı ve kullanılmadığı durumlarda karşılaştırmalar yapılmıştır. Elde edilen sonuçlar ile geliştirilen modellerin geleneksel olarak kullanılan modellere göre sistemi kısa sürede kararlı hale getirdiği ve salınımların azalttığı görülmüştür.

Enhancement of UPFC, PODC and Sub-Transient Dynamic Model for Transient Stability in Power Systems

Öz

During power system operation, it faces instability problems thanks to some reason. One of the most important causes of instability problems is short circuit conditions. It causes oscillations in power systems. Power Swing Damping Control (PSDC) is used to eliminate these oscillations. In this study, analyzes were carried out with different scenarios in Kundur 4 machine system in order to dampen oscillations in power systems. In addition, sub-transient state dynamic models of synchronous generators used in multi-machine system are preferred in this study. Comparisons were made when Unified Power Flow Controller (UPFC), PSDC, and sub-transient state dynamic models were used and not used. It has been observed that the models developed with the results obtained have stabilized the system in a short time and the oscillations decreased compared to the traditionally used models.
