Hibrit UPS'lerin Sağladığı Bazı İmkanların Deneysel Olarak İncelenmesi

Abstract

Tüketiciye kesintisiz ve kaliteli enerji sağlamak amacıyla kullanılan Kesintisiz Güç Kaynakları (KGK) da enerji sektöründeki gelişmelere paralel olarak değişimlere uğramıştır. Bu süreçte güç elektroniği elemanlarındaki gelişmelerle konvansiyonel KGK'ların verimliliği artmış, trafosuz KGK’lar ile boyutları ve ağırlıkları azaltılmıştır. Son zamanlarda yenilenebilir enerji sistemlerindeki gelişmelere kayıtsız kalmayan KGK sistemleri, bu sistemlerden elde edilen enerjiyi kullanarak hibrit bir yapıya kavuşmuştur. Bu çalışmada, hibrit KGK'ların çeşitli avantajları, referans bir hibrit KGK üzerinden, giriş/çıkış akımı/gerilim dalga formu aracılığıyla deneysel olarak incelenmiştir. Bu kapsamda hibrit KGK’ların yükün sadece PV sistem üzerinden beslenmesi, yükün şebekeden ve PV sistemden beraber beslenmesi, şebekeye bağlı/şebekeden bağımsız çalışmaya uyum sağlaması gibi çeşitli özellikleri incelenmiştir. Sonuçlar, hibrit KGK’ların kesintisiz, yüksek kaliteli ve verimli enerji sağlama konusunda umut verici olduğunu göstermektedir.

Experimentally Investigation of Some Facilities Provided by Hybrid UPSs

Abstract

Uninterruptible power supplies (UPS), which are used to provide uninterrupted and high-quality energy to the consumer, have also changed in parallel with the developments in the energy sector. In the process, the efficiency of conventional UPSs has increased by developments in power electronics elements, and the dimensions and weights have been reduced with the transformerless UPSs. Recently, UPS systems, which are not indifferent to the developments in renewable energy systems, have achieved a hybrid structure using the energy obtained from these systems. In this study, various advantages of these UPSs are examined experimentally over a sample hybrid UPS via input/output current/voltage waveform. In this context, several features of hybrid UPSs such as feeding the load only through the PV system, supplying the load from the grid and PV system, adapting to on-grid/off-grid operation were examined. The results show that hybrid UPSs are promising in providing uninterrupted, high quality, and efficient energy.
