Bu çalışmada bir fazlı şebeke etkileşimli eviricinin LCL filtre parametreleri hesap edilmiştir. Hesap edilen LCL filtre parametrelerinin ve seri sönümleme direncinin %50 artması ve azalması durumunda şebeke akımının toplam harmonik bozulma (THD) ve kayıp güç değerlerinin değişimi analiz edilerek en uygun değerler belirlenmiştir. Analiz çalışmaları PSIM benzetim programı kullanılarak gerçekleştirilmiştir. Çalışma 1 kW gücünde olup akım kontrolünde oransal rezonans (PR) kontrol, PLL algoritmasında ise T/4 gecikmeli PLL yapısı kullanılmıştır. Analiz sonuçlarına göre bobin değerlerinin arttırılması akımın THD değerini ve kayıp güç miktarını düşürdüğü belirlenmiştir. Sönümleme direnç değerinin düşürülmesi de yine THD ve kayıp güç değerlerini düşürmektedir. LCL filtre tasarımında bobin değerlerinin arttırılması, seri sönümleme direnç değerinin ise düşürülmesinin uygun olacağı görülmüştür.

Change Effect of LCL Filter Parameter Values and Series Damping Resistor Value in Single Phase Grid Connected Inverter

Öz

In this study, LCL filter parameters of a single-phase grid-connected inverter were calculated. The change of total harmonic distortion (THD) of the grid current and power loss values when the calculated LCL filter parameters and series damping resistor were increased and decreased by 50% was analyzed and the most appropriate values were determined. Analysis studies were carried out using the PSIM simulation program. The study had a power of 1 kW and proportional resonant (PR) control was used in current control and T/4 delay PLL structure was used in PLL algorithm. According to the results of the analysis, it was determined that increasing the inductor values decreased the THD value of the current and the amount of power loss. In addition, decreasing the damping resistor value also decreased THD and power loss values. In LCL filter design, it was seen that it would be appropriate to increase the inductor values and to decrease the series damping resistor value.
