Şebeke destekli harmonik gerilim kaynağının tasarımı ve uygulaması

Bu çalışmada, genel amaçlı güç kalitesi deneysel çalışmalarında ve aktif güç filtre deneysel laboratuar ortamında kullanmak üzere, gerilim kaynaklı harmonik ve güç kalitesi problemleri oluşturmak amacıyla şebeke destekli Harmonik Gerilim Kaynağı (HGK) tasarımı açıklanmakta ve yeni bir denetim yöntemi ile uygulama sonuçları verilmektedir. Önerilen sistem, alçak gerilim seviyesinde 5kW‘lık bir prototip ile test edilerek gerçek zamanlı uygulama ve fizibilite çalışmaları sunulmaktadır. Farklı tipte gerilim kaynaklı güç kalitesi problemlerinde kullanılabilecek (harmonikler, dengesizlik, çökme-yükselme, vb.) karmaşık matematiksel hesaplamalar gerektirmeyen oldukça basit bir denetim yöntemi önerilmektedir.

Design and implementation of grid based harmonic voltage source

This paper presents design and implementation of a new type of grid-based harmonic voltage source (HVS) that can be used in general power quality experimental studies and experimental active power filter applications in order to create voltage source harmonics and power quality problems. Their experimental results and feasibility of the proposed system were explained in detail. The proposed system has been tested in real time low voltage level in a 5 kW laboratory prototype. The proposed method has very easy mathematical calculations in order to create different types of voltage source based power quality problems (harmonics, unbalances, and voltage sag and swell etc.).
