Bir Tekstil Üretim Tesisinde Süreç Temelli Harmonik Profilleri ve Göreceli Araştırma Öncelikleri

Öz

Doğrusal olmayan yüklerin yoğun olduğu endüstriyel tesislerde harmonik bozulma, yük ve proses özelliklerine bağlı olarak değişebilmektedir. Bu çalışmada, bir tekstil tesisindeki altı üretim ve yardımcı işletme noktasına ait üç fazlı saha ölçümleri analiz edilmiştir. Hazırlama–ısıtıcı, hazırlama–sürücü, büküm, fikse–buhar, kompresör–hava ve kompresör–kurutucu noktalarında akım toplam harmonik bozulması (THDI), gerilim toplam harmonik bozulması (THDV), toplam güç faktörü, yer değiştirme güç faktörü ve belirgin harmonik bileşenler incelenmiştir. Kompanzasyonu devre dışı bırakılan 2500 kVA transformatöre ait ölçüm ise tesis referansı olarak kullanılmıştır. Proseslerin göreli inceleme öncelikleri, ortalama THDI, ortalama THDV ve güç faktörü ayrışmasına dayalı eşit ağırlıklı keşifsel bir puanla belirlenmiştir. En yüksek ortalama ve maksimum THDI değerleri fikse–buhar prosesinde sırasıyla %61,79 ve %64,62 olarak belirlenirken, en yüksek faz THDV değeri kompresör–hava prosesinde %8,05 olarak ölçülmüştür. Göreli sıralamada fikse–buharı kompresör–hava ve büküm izlemiştir. Tesis referansındaki ortalama THDI değerinin bazı proseslerden düşük olması, tesis düzeyindeki tek bir ölçümün yerel harmonik farklılıkları yeterince yansıtmayabileceğini göstermiştir. Bulgular, güç kalitesi değerlendirmelerinin proses düzeyindeki eş zamanlı ve uzun süreli ölçümlerle desteklenmesi gerektiğini ortaya koymaktadır.

Process-Based Harmonic Profiles and Relative Investigation Priorities in a Textile Manufacturing Facility

Öz

In industrial facilities with a high concentration of nonlinear loads, harmonic distortion can vary depending on load and process characteristics. In this study, three-phase field measurements from six production and auxiliary operation points at a textile plant were analyzed. Total harmonic distortion of current (THDI), total harmonic distortion of voltage (THDV), total power factor, displacement power factor, and prominent harmonic components were examined at the preparation–heater, preparation–drive, twisting, steam fixation, air compressor, and compressor dryer points. Measurements from a 2,500 kVA transformer with compensation disabled were used as the facility reference. The relative priorities for examining the processes were determined using an equally weighted exploratory score based on average THDI, average THDV, and power-factor separation. The highest average and maximum THDI values were determined to be 61.79% and 64.62%, respectively, in the steam fixation process, while the highest phase THDV value was measured at 8.05% in the air compressor process. In the relative ranking, the steam fixation process was followed by the air compressor and twisting processes. The fact that the average THDI value at the facility level was lower than that of some processes indicates that a single measurement at the facility level may not adequately reflect local harmonic differences. The findings demonstrate that power quality assessments must be supported by simultaneous, long-term measurements at the process level.
