Özet:

 Grid connected Doubly Fed Induction Generator DFIG based wind turbines are highly affected by transient stability conditions such as symmetric and asymmetric faults. In order for the DFIG to remain connected to the grid in case of transient stability for a certain period of time, a grid code requirement for Low Voltage Ride Through LVRT Capability is needed. For this purpose, it is necessary to create a dynamic model-based simulation of DFIG. In this study, it is aimed to develop a 3rd order model in creating a dynamic model in DFIG. In addition to stator dynamics, rotor dynamic modeling is developed in this study. Comparisons of the developed 3rd order model with the traditionally used 5th order model are made for 3 phase fault, 2 phase fault and 1 phase ground fault situations. Parameters used were 34.5 kV bus voltage, DFIG output voltage, angular speed and active power. As a result of the results obtained, it was seen that the 3rd degree model developed gave better results than the 5th degree model in stabilizing the system in a short time and damping the oscillations.

 Şebekeye bağlı Çift Beslemeli Asenkron Generatör ÇBAG tabanlı rüzgar türbinleri simetrik ve asimetrik arıza gibi geçici kararlılık durumlarından çok etkilenmektedir. Belirli bir süre geçici kararlılık durumunda ÇBAGın şebekeye bağlı kalması için Düşük Gerilim İyileştirme Yeteneği DGİY için şebeke kod gereksinimine ihtiyaç olmaktadır. Bunun için ÇBAGın dinamik model tabanlı benzetiminin oluşturulması gereklidir. Yapılan bu çalışmada, ÇBAGda dinamik model oluşturulmasında 3. derece modelinin geliştirilmesi amaçlanmıştır. Stator dinamiğinin yanı sıra rotor dinamik modellemesi de bu çalışmada geliştirilmiştir. Geliştirilen 3. derece model ile geleneksel olarak kullanılan 5. derece modelin karşılaştırmaları 3 faz arızası 2 faz arızası ve 1 faz toprak arızası durumları için yapılmıştır. Parametreler olarak 34.5 kV bara gerilimi, ÇBAG çıkış gerilimi, açısal hız ve aktif güç kullanılmıştır. Elde edilen sonuçlar neticesinde, sistemin kısa sürede kararlı hale gelmesi ve salınımların sönümlenmesinde geliştirilen 3. derece modelin 5. derece modele göre daha iyi sonuçlar verdiği görülmüştür.
