Abstract

The quality of energy is great importance as much as the electricity is required in power systems. One of the most important factors affecting the power quality is the harmonics resulting from non-linear loads in the system. In recent years, the development of the power electronics causes non-linear loads to increase. Correspondingly, it causes waveform distortions and harmonics in power systems. Harmonics cause technical and economical losses in the system. Except for some precaution to take in the design phase of a power system, the most important method for reducing harmonics is the use of harmonic filters. In this study, harmonic measurements of fluorescent lamp with electronic ballast are taken. Thereafter, passive filters are designed to reduce harmonics, their effects and decreases in Total Harmonics Distortion (THD) values are observed. Single-tuned and double-tuned models are used in filter design. The same system is modeled in Matlab/Simulink, the theoretical results are compared with measurement results.

Özet

Elektrik tesislerinde elektrik enerjisine olan ihtiyaç kadar enerjinin kalitesi de büyük önem taşımaktadır. Güç kalitesini etkileyen en önemli unsurlardan biri, sistemdeki lineer olmayan yüklerden kaynaklanan harmoniklerdir. Son yıllarda güç elektroniğinin gelişimiyle artan lineer olmayan yükler, elektrik tesislerinde dalga şekillerinin bozulmasına ve harmoniklerin oluşmasına neden olmaktadır. Sistemdeki harmonikler ekonomik ve teknik zararlara neden olmaktadır. Bir tesisin tasarımı aşamasında alınacak bazı önlemler dışında, harmoniklerin azaltılması için en önemli yöntem harmonik filtrelerin kullanılmasıdır. Bu çalışmada, elektronik balastlı bir floresan lambanın çalışma durumlarına ilişkin harmonik ölçümleri alınmıştır. Daha sonra, ölçülen harmonikleri azaltmak amacıyla pasif filtreler tasarlanarak etkileri ve Toplam harmonik bozunum (THB) değerlerindeki azalmalar gözlemlenmiştir. Filtre tasarımında tek ayarlı ve çift ayarlı modeller kullanılmıştır. Aynı sistem, Matlab/Simulink ortamında modellenerek, ölçüm ile teorik sonuçlar karşılaştırılmıştır.
