Abstract

In grid interactive power converter applications, phase locked loop (PLL) methods are very important to realize grid synchronization. The performance of PLL which is used should be affected by adverse conditions such as voltage unbalance, harmonics, frequency and phase changes. Furthermore, in these adverse conditions, the phase angle of grid voltages and positive sequence component of grid voltages in fundamental grid frequency are needed to determine quickly and accurately. Otherwise, synchronization errors occur between the grid interactive inverter and the grid.
In this paper, different PLL methods are simulated under MATLAB/Simulink. The performances of the PLL methods are comparatively presented under three different conditions such as unbalanced, harmonics and variable frequency grid. It has also put forward the positive and negative aspects of the PLL methods based on the obtained results.

ŞEBEKE ETKİLEŞİMLİ EVİRİCİLER İÇİN FAZ KİLİTLEME DÖNGÜSÜ YÖNTEMLERİNİN PERFORMANSLARININ KARŞILAŞTIRILMASI

Abstract

Şebeke etkileşimli güç dönüştürücü uygulamalarında, şebeke senkronizasyonunun gerçekleştirilebilmesi için faz kilitleme döngüsü (PLL) yöntemleri oldukça önemlidir. Kullanılan PLL’nin performansı; gerilim dengesizliği, harmonikler, frekans ve faz değişimi vb. olumsuz durumlardan etkilenmemelidir. Üstelik bu olumsuz durumlarda, şebeke faz açısının ve temel şebeke frekansındaki pozitif sıralı bileşen geriliminin hızlı ve doğru bir şekilde belirlenmesi gerekir. Aksi durumda, şebeke etkileşimli dönüştürücü ile şebeke arasında senkronizasyon hataları meydana gelmektedir.
Bu makalede, farklı PLL yöntemlerinin MATLAB/Simulink’te benzetimi yapılmıştır. Dengesiz, harmonikli ve değişken frekanslı şebeke durumu gibi üç farklı şebeke koşulu altında PLL yöntemlerinin performansları karşılaştırmalı olarak sunulmuştur. Ayrıca, elde edilen sonuçlara dayanarak PLL yöntemlerinin artı ve eksi yönleri ortaya konulmuştur.
