Güç sistemlerinde farklı güç sistemi kararlı kılıcısı modellerin sekonder gerilim kontrolü üzerindeki etkileri

Abstract

Güç sistemleri hat kopması ve kısa devre gibi geçici durumlara karşı korunmasızdır. Kararsızlık problemlerini en kısa süre içerisinde ortadan kaldırmak için çeşitli modeller kullanılmaktadır. Özellikle de senkron generatör denetleyici kısımlarında Güç Sistemi Kararlı Kılıcısı (GSKK) yaygın olarak kullanılmaktadır. Bu çalışmada IEEE’nin 14 baralı sisteminde farklı GSKK modellerinin sekonder gerilim kontrolü ile beraber kullanılması ile geçici durum kararlılığı detaylı olarak incelenmiştir. Buna ek olarak, farklı GSKK modellerinin ve sekonder gerilim kontrolünün koordineli olarak çalışması için Otomatik Gerilim Regülatörü (OGR)’nin en uygun modeli ile beraber kullanımı düşünülmektedir. Merkezi alan kontrolü ve küme kontrolünden oluşan sekonder gerilim kontrolünün kullanımı için pilot bara belirlenmiş olup, senkron generatörde OGR ve GSKK modellerinin koordinasyon kontrolünün sağlanması amaçlanmıştır. Bu çalışma Güç Sistemleri Analizi Programı (PSAT) kullanılarak analiz edilmiştir. Farklı GSKK modellerinin kullanılması ile senkron generatör açısal hız değişimleri, bara gerilim profilleri ve senkron generatör aktif-reaktif güç değişimleri incelenmiştir. Yapılan çalışma sonucunda GSKK 2 modelinin diğer modellere göre kısa süre içerisinde sistem kararlılığını sağladığı ve salınımları azalttığı görülmüştür.

Effects on secondary voltage control of different power system stabilizer models in power systems

Abstract

Power systems are vulnerable to transients such as line contingency and short circuit. Various models are used to eliminate instability problems as soon as possible. In particular, the Power System Stabilizer (PSS), which is one of the synchronous generator controller models, is widely used. In this study, the transient stability of IEEE's 14 bus system was investigated in detail by using different PSS models together with secondary voltage control. In addition, it is considered to use the Automatic Voltage Regulator (AVR) together with the most suitable model for the coordinated operation of different PSS models and secondary voltage control. The pilot bus has been determined for the use of secondary voltage control consisting of central area control and cluster control, and it is aimed to provide coordination control of AVR and PSS models in the synchronous generator. This study was analyzed using the Power Systems Analysis Program (PSAT). By using different PSS models, synchronous generator angular speed changes, bus voltage profiles, and synchronous generator active-reactive power changes were investigated. As a result of the study, it was seen that the PSS 2 model provided system stability and reduced oscillations in a short time compared to other models.
