Abstract

In this study, active power (P), apparent power (S), reactive power (Q), displacement power factor (dPF), harmonic power factor (PF) and % total harmonic distortion for current (%THDI) values were analysed in a plant producing irrigation systems and packaging materials when reactive power compensation was OFF and ON in three phases. In systems where harmonics are present, the effect of reactive power compensation on total harmonic distortion is analysed by measuring with three analysers when reactive power compensation is OFF and ON. In other words, the study analyses in detail how reactive power compensation affects %THDI. PF, dPF and %THDI values are analysed graphically in OFF and ON state of reactive power compensation. In the study, it was found that the %THDI value measured when the reactive power compensation is OFF is higher than when the reactive power compensation is ON. The results in the paper show that the %THDI value of reactive power compensation increased from 8.45% to 15.63% with a minimum difference of 7.180% and from 7.64% to 26.36% with a maximum difference of 18.723%.

Toplam Harmonik Bozulma Seviyesinin Reaktif Güç Kompanzasyonuna Bağlı Değişimi

Abstract

Yapılan çalışmada, sulama sistemleri ve ambalaj malzemesi üreten tesiste, üç fazda reaktif güç kompanzasyonu devre dışı (OFF) ve devrede (ON) iken aktif güç (P), görünür güç (S), reaktif güç (Q), yerdeğiştirme güç faktörü (dPF), harmonikli güç faktörü (PF) ve akım için % toplam harmonik bozulma (%THDI) değerleri incelenmiştir. Harmoniklerin mevcut olduğu sistemlerde reaktif güç kompanzasyonu OFF ve ON iken güç analizörü ile ölçüm yapılarak reaktif güç kompanzasyonunun toplam harmonik bozulmaya etkisi analiz edilmiştir. Diğer bir ifade ile çalışma; ayrıntılı bir şekilde reaktif güç kompanzasyonunun %THDI’ye nasıl etki ettiğine dair analizler yapılmıştır. Reaktif güç kompanzasyonu OFF ve ON durumunda PF ve dPF ile %THDI değerleri grafiksel olarak incelenmiştir. Çalışmada, reaktif güç kompanzasyonu OFF durumunda iken ölçülen %THDI değerinin, reaktif güç kompanzasyonu ON durumunda iken daha yüksek değerde olduğu tespit edilmiştir. Makaledeki sonuçlar, reaktif güç kompanzasyonun %THDI değerini minimum %7,180 fark ile %8,45’ten %15,63’e, makimum ise %18,723 fark ile %7,64’den %26,36’e yükseltmiştir.
