Abstract
Elektrik enerjisinin üretim-tüketim dengesinin korunması, değişik yük taleplerinin karşılanması veya sistemde meydana gelebilecek geçici ve kalıcı arızaların elimine edilmesi oldukça önemlidir. Yaşam kalitesini artırmak için geliştirilen yeni cihazların dengesiz güç tüketimleri ve sürekli artan enerji ihtiyacı elektrik güç sistemlerinin enerji kalitesini, şebeke verimini ve enerji verimini düşürmektedir. Giderek karmaşık hale gelen elektrik şebekelerindeki başlıca problemler; aktif-reaktif güç dengesizlikleri, harmonikler, gerilim dengesizlikleri, geçici ve kalıcı arızalar olarak sıralanabilir. Bu çalışmada yaklaşık olarak 20 MW kurulu güce sahip olan bir dal-budak elektrik şebekesi aktif-reaktif güç dengesi ve gerilim kalitesi analiz edilerek şebekede meydana gelen güç dengesizlikleri ve arızalar tespit edilmiştir. Şebekedeki reaktif güç problemini elimine etmek için şebekeye dinamik kontrollü OG ve AG kompanzasyon uygulaması yapılmış ve bu uygulamayla aktif-reaktif güç dengesi, izin verilen yasal sınırlar içinde olacak şekilde ayarlanmıştır. Yapılan dinamik kompanzasyon uygulaması sayesinde şebeke güç oranları belirtilen sınırlar içinde tutulmuş ve gerilimi daha kararlı hale getirilirken güç faktöründe de iyileştirme sağlanmıştır.
