Çoklu seri ve paralel kompanzatörler ile güç sistemlerinde geçici kararlılık analizi

Öz

Bu çalışmada çok baralı bir güç sisteminin geçici kararlılık durumunda çoklu seri ve parallel kompanzatörlerin etkileri incelenmiştir. 22 bara çok makinalı gerçek sistemin Statik Senkron Kompazatör (STATCOM) ve Statik Senkron Seri Kompanzatör (SSSC) ile modellemesi yapılmıştır. Kompanzatörlerin yerleşimi geçici durum esnasında hatlardaki en yüksek gerilim düşümüne ve zayıf baraya bağlı olarak belirlenmiştir. Geçici kararlılık durumu STATCOM and SSSC olmadığı durum, STATCOM and SSSC olduğu durum ve STATCOM and SSSC çoklu olduğu durumda incelenmiştir. Bunu yanısıra baraların gerilim değişimleri ve senkron generatorlerin açısal hız değişimleri incelenmiştir. Çoklu STATCOM and SSSC kullanımı ile geçici kararsızlık durumunda kısa zaman içerisinde salınımların azaldığı görülmüştür.

Analysis of transient stability in power systems with multiple shunt and series compensators

Abstract

This study investigates the effect of multiple shunt and series compensators in transient stability case of a multi-machines power system. 22 bus multi machine real systems are modeled with Static Synchronous Compensator (STATCOM) and Static Synchronous Series Compensator (SSSC). The locations of the compensators are identified depending on the weak buses and transmission lines with highest voltage dip during transient cases. Transient stability cases are examined without STATCOM and SSSC, with STATCOM and SSSC multiple STATCOM and SSSC. Besides, Angular speeds of synchronous generators and variations voltage of buses are examined. Oscillations can decrease within short time with multiple STATCOM and SSSC in transient instability case.
