BAĞIMSIZ RÜZGAR ENERJİSİ SİSTEMLERİNDE GÜÇ KALİTESİNİ İYİLEŞTİRMEK İÇİN DEĞİŞKEN ÇALIŞMA KOŞULLARINDA DİNAMİK GERİLİM ONARICININ UYGULANMASI

Öz

Hassas yüklerin yenilenebilir enerji kaynaklarından beslendiği güç sistemlerinde, gerilim dalgalanmaları ve elektrik kesintileri, yükün talep ettiği gerilimin karşılanmaması veya yükün yüksek harmonik bozulmaya sahip bir gerilimle beslenmesiyle sonuçlanabilir. Bu durum, bir süre sonra hassas yüke zarar verebilir hatta yükün çalışamaz hale gelmesine neden olabilir. Bu çalışmada, güç kalitesini iyileştirmek için bağımsız bir rüzgar türbini güç sistemine dinamik gerilim onarıcı (DVR) uygulanmıştır. DVR teknolojisi, güç sistemini sürekli olarak izler ve olası gerilim düşüşleri, yükselmeleri veya dalgalanmaları durumunda sistemin ihtiyaç duyduğu gerilimi belirleyerek, sisteme seri bağlı şekilde enjekte eder. Bu çalışmanın amacı, kaynak ve yük arasında beklenmeyen elektriksel arızalar olması durumunda yük geriliminin nominal çalışma koşullarında performans göstermesini sağlayarak sistem güvenilirliğini ve kalitesini artırmaktır. Önerilen uygulama farklı yüklerde (doğrusal ve doğrusal olmayan), rüzgar hızlarında (14 -16 m/s), faz gerilim arızalarında ve kaynak frekanslarında test edilmiştir. Farklı çalışma koşullarında, yük geriliminin THD'si <%5'te tutulmuştur (IEEE-519 standartlarına uygun). Ayrıca, gerilim düşüşleri ve yükselmeleri başarıyla telafi edilerek sistemin kararlılığı ve güvenilirliği teyit edilmiştir.

APPLICATION OF DYNAMIC VOLTAGE RESTORER TO IMPROVE POWER QUALITY IN STAND-ALONE WIND POWER SYSTEMS UNDER VARIABLE OPERATING CONDITIONS

Abstract

In power systems where sensitive loads are supplied by renewable energy sources, voltage fluctuations and power outages may result in the voltage demanded by the load not being met or the load being supplied with a voltage with high harmonic distortion. This may damage the sensitive load after a while or even cause the load to become inoperable. In this study, a dynamic voltage restorer (DVR) was implemented in a stand-alone wind turbine power system to improve the power quality. DVR technology continuously monitors the power system and injects series voltage as needed in case of possible voltage sags, swells, or fluctuations. The aim of this study is to increase system reliability and quality by ensuring the load voltage performs at nominal operating conditions even in the event of unexpected electrical faults between the source and the load. The proposed application was tested at different loads (linear and non-linear), wind speeds (14 -16 m/s), phase voltage faults, and source frequencies. In different operating conditions, the THD of the load voltage was kept at <5% (compliant with IEEE-519 standards). Additionally, voltage sags and swells have been successfully compensated and confirming the system stability and reliability.
