Abstract

In this study, L, LCL and LLCL type filters were designed for single phase grid connected inverter and filter types were compared with each other. For the design, filter parameter values were calculated so that the total harmonic distortion (THD) value of the grid current would be below 5%. After the filter parameter values were determined, simulation studies were carried out in the PSIM program. In the study, the codes required for active power control, proportional-resonant (PR) current control and enhanced phase locked loop (PLL) control were written in the C block. The simulation results showed that while the 1 kW power was transferred to the 220 V AC grid, the highest THD value was obtained as 4.92% in the L type filter, while the lowest THD value was as 0.99% in the LLCL filter type. According to the filter design, the filter type with the highest inductance value was found to be the L filter. Although THD values were low in LCL and LLCL filter types, it was seen that it was important to choose appropriate parameter values.

Abstract

Bu çalışmada, tek fazlı şebeke bağlantılı evirici için L, LCL ve LLCL tipi filtre tasarımları yapılarak filtre tipleri birbirleri ile kıyaslanmıştır. Tasarım için şebeke akımının toplam harmonik bozulma (THD) değeri %5’in altında oluşacak şekilde filtre parametre değerleri hesaplanmıştır. Filtre parametre değerleri belirlendikten sonra PSIM programında simülasyon çalışmaları gerçekleştirilmiştir. Çalışmada aktif güç kontrolü, oransal-rezonans (PR) akım kontrolü ve gelişmiş faz kilitlemeli döngü (PLL) kontrolü için gerekli olan kodlar C bloğu içerisine yazılmıştır. Simülasyon sonuçlarına göre 1 kW güç, 220 V AC şebekeye aktarılırken en yüksek THD değeri %4.92 olarak L tipi filtrede elde edilirken, en düşük THD değeri %0.99 olarak LLCL filtre tipinde oluşmuştur. Yapılan filtre tasarımına göre endüktans değeri en yüksek olan filtre tipi de L filtredir. LCL ve LLCL filtre tiplerinde THD değerleri düşük çıkmasına rağmen uygun parametre değerlerinin seçilmesinin önemli olduğu görülmüştür.
