Abstract:

 

Bu çalışmada, güç sistemlerindeki akım ve gerilim dalga şekillerindeki bozukluklar, dalgacık dönüşümü yardımıyla tespit edilmeye çalışılmıştır. Gerçekleştirilen çalışmada dalgacık dönüşümü hem benzetim yoluyla üretilen dalga şekli bozukluklarına hem de gerçek sistemden ölçülen dalga şekillerine uygulanmıştır. Her iki uygulamada da akım ve gerilim dalga şekli bozuklukları, dalgacık analizi ile kolaylıkla tespit edilmiştir. Analiz sonuçları, dalgacık dönüşümünün özellikle enerji kalitesinin değerlendirildiği ve uzun süreli kayıt gerektiren güç sistemlerinde, akım ve gerilim dalga şekli bozukluklarının tespiti için yararlı sonuçlar üreten bir metot olduğunu göstermektedir.

 

In this study, the disturbances of voltage and current waveforms at power systems are detected by using the wavelet transform. In the realized work, the wavelet transform is applied to the waveform disturbances obtained by simulation and the waveform measured from a real system. The disturbances of waveforms are easily detected with wavelet transform for both of applications. The results of analysis show that wavelet transform is useful method to detect the disturbances of voltage and current waveforms especially for power systems where evaluation of power quality and long time data record are required.
