Abstract

The harmonic currents injected to electric power system including of linear and nonlinear loads are increasing due to the increase in nonlinear loads. Harmonic currents not only cause deterioration in load wave forms but also provide negative effects on power system and equipments connected to power system.
The evaluation of the technical and economical effects of harmonics and providing analysis in plants about this issue are significantly important both for energy quality and plant durability. In this study, the effects of harmonics are evaluated and the need of a harmonic filter that provides the possibility of filtering the desired harmonic current. Harmonic filters requires different design approaches for each plant, thus the important issues in filtering are examined. The power compensation in energy systems fed by sinusoidal source and including linear loads can be realized easily. However, the power compensation in the case of non-sinusoidal source or nonlinear loads may cause some difficulties. Thus, the power compensation in harmonic condition is even more difficult than normal power compensation applications. In the realized study, the significant issues about this topic are presented.
In this study, the realization of filtering and power compensation in non-sinusoidal load conditions is evaluated and some information is provided on this topic. Besides, the measurements on a real plant as well as the filtering and power compensation studies on the mentioned plant are presented.

Abstract

Lineer ve nonlineer yüklerin bulunduğu elektrik güç sisteminde, nonlineer yüklerin günden güne artmasına bağlı olarak sisteme enjekte edilen harmonik akımları da artmaktadır. Harmonik akımlar, sadece yüklerin dalga şekillerinde bozucu etkilerde bulunmayıp aynı zamanda güç sisteminde ve güç sistemine bağlanan elemanlar üzerinde de olumsuz etkiler meydana getirmektedirler.
Teknik ve ekonomik bakımdan pek çok etkisi olan harmoniklerin bu etkilerinin bilinmesi ve işletmelerde analizlerinin yapılması, hem enerji kalitesi açısından hem de işletmenin sürekliliği açısından son derece önemlidir. Gerçekleştirilen çalışmada çeşitli nonlineer yüklerin bulunduğu bir sistemde, harmoniklerin etkileri belirtilip sistemde istenen harmonik akımının süzülmesini sağlayan harmonik filtresinin gerekliliği anlatılmaktadır. Harmonik filtreler her tesis için ayrı ayrı tasarım gerektirir, dolayısıyla filtrelemede dikkat edilmesi gereken hususlar incelenmektedir. Sinüs biçimli kaynaktan beslenen ve lineer elemanlardan meydana gelen enerji sistemlerinin güç kompanzasyonu basit bir inceleme ile yapılabilmektedir. Fakat besleme kaynağının sinüs biçimli olmaması veya elemanların nonlineer karakterde olması durumunda güç kompanzasyonunda bir takım zorluklar yaşanmaktadır. Bu yüzden harmonikli sistemlerde güç kompanzasyonu normal kompanzasyondan farklıdır. Yapılan çalışmada bu konuda dikkat edilmesi gereken hususlar belirtilmektedir.
Bu çalışmada, öncelikle filtreleme ve güç kompanzasyonunun sinüs biçimli olmayan sistem için gerçekleştirilmesi irdelenmektedir ve buna ait bilgiler verilmektedir. Ayrıca çalışmada gerçek bir sistem üzerinde yapılan ölçümler ile bu sistemin filtrelenmesi ve güç kompanzasyonunun gerçekleştirilmesi de yer almaktadır.
