Bu çalışmada, Birleşik Güç Kalite Düzenleyicisi (BGKD) ile şebeke gerilim ve yük akım harmoniklerinidüzelterek sistemin güç kalitesi problemlerinin iyileştirilmesi açıklanmaktadır. Birleşik güç kalite düzenleyicisiortak bir DC hattı paylaşan paralel ve seri aktif güç filtre sistemlerinin birlikte kullanılması ile oluşmaktadır.Paralel aktif güç filtresi ile akım harmonikleri, yük akım dengesizlikleri, reaktif güç ve nötr akımıkompansazyonu yapılmakta, seri aktif güç filtresi ile kaynak gerilim harmonikleri, dengesizlikleri ve gerilimçökme-yükselme gibi güç kalitesi problemleri düzeltilmektedir. BGKD için önerilen denetim algoritmasınınlaboratuar ortamında uygulaması yapılmaktadır. Ayrıca Matlab/Simulink yazılımı ile önerilen denetimalgoritmasının simülasyonu yapılarak sistemin performansı incelenmektedir. Önerilen BGKD denetimalgoritması güç dağıtım sistemindeki ortak bağlantı noktasında güç kalitesini iyileştirmektedir.

Power quality improvement with UPQC in 3-phase 4-wire systems

This paper presents a new control method to compensate source voltage and load current harmonics andimprovement of power quality problems through a three-phase unified power quality conditioner (UPQC). TheUPQC system consists of combined operation of series and shunt active power filters sharing a common DClink. Paralel Active Power Filter (PAF) used for current harmonics, unbalanced and neutral currentcompensation; Series Active Power Filter (SAF) used for compensation of source voltage harmonics, unbalancedvoltage and sag and swell of source voltage. The performance of the proposed control system was analyzedusing simulations with Matlab/Simulink program, and experimental results with the hardware prototype. Theproposed UPQC control algorithm can improve the power quality at the point of common coupling (PCC) onpower distribution system.
