TRİSTÖR ANAHTARLAMALI KAPASİTÖR (TSC) VE TRİSTÖR ANAHTARLAMALI REAKTÖR-TABANLI STATİK VAr KOMPANZATÖR’ÜN (TSR-TABANLI SVC) PI İLE KONTROLÜ

Guc elektronigi cihazlarinin akim ve gerilim tutma kapasitelerinin gelismesi ile birlikte, etkili bir paralel ve seri kompanzasyon icin farkli tip kontrolorlerin kullanimi da artmistir. Bu nedenle en cok onerilen kontrolorlerden biri Esnek AC Iletim Sistemleri (FACTS, Flexible AC Transmission Systems) olarak bilinen guc elektronigi tabanli kontrolorler ailesidir. Bu calismada, paralel FACTS cihazlarindan ikisi olan Tristor Anahtarlamali Kapasitor (TSC) ve Tristor Anahtarlamali Reaktor (TSR)-tabanli Statik VAr Kompanzator (SVC)’nin yuk barasi gerilimine olan etkisi incelenmistir. Alti Darbe Ureteci ve PI (Proportional Integral) Kontrolor TSC ve TSRtabanli SVC’nin tetikleme acilarinin kontrolu icin kullanilmistir. Bu kompanzatorler; Matlab/Simulink Guc Sistemleri Arackutucugu (Power Systems Toolbox) kullanilarak simule edilmistir. Uzerinde calisilan uc fazli guc sistemi; iki barali olup statik yuk ve uzun iletim hatti modeline sahiptir. Yapilan benzetim sonuclari; PI kontrolorun bu tip kompanzatorlere kolaylikla uygulanabilecegini gostermistir.
