SÜREKLİ YÜK AKIŞINDA STATİK GERİLİM KARARLILIĞINA STATCOM VE SSSC’NİN ETKİSİNİN İNCELENMESİ

Bu çalışmada türkiyedeki 22 baralı bir güç sisteminde statik gerilim kararlılığı FACTS cihazlarından STATCOM ve SSSC ile incelenmiştir. Farklı yük baralarına STATCOM’un bağlanması ve farklı iletim hatlarına SSSC’nin bağlanması ile güç sisteminin gerilim ve maksimum yüklenme parametreleri arasındaki ilişki belirlenmiştir. Bu benzetim çalışması Güç Sistemleri Araç Kutusu Analizi (PSAT) ile incelenmiştir. Bazı yük baralarındaki statik gerilim kararlılığı sonuçları şekiller ve tablo halinde sunulmuştur. Sürekli güç akışının yapıldığı bu sistemde STATCOM ve SSSC’nin kullanılması ile yük baralarında statik gerilim kararlılığının iyileştirildiği bulunmuştur.

INVESTIGATION OF THE EFFECTS OF STATCOM AND SSSC STATIC VOLTAGE STABILITY CONTINUATION POWER FLOW OPERATION

In this study, static voltage stability of Turkey 22 bus power system was been examined by using STATCOM and SSSC that known as FACTS devices. According to STATCOM and SSSC connected to different load busses and different transmission lines, the relationship of power system between voltage and maximum load parameters was determined. Voltage stability results of some load busses are presented in figures and tables. At this system that was made continuous power flow, through use of STATCOM and SSSC healing to voltage stability of load busses was revealed.
