Abstract

Currents injected into grid need to have a total harmonic distortion below 5% in grid connected inverters. To this aim, output filters are employed. For these filters, design conditions other than total harmonic distortion for voltage drop over the filter and reactive power consumption of the filter have to be also fulfilled. In literature, some filter schemes have been proposed to satisfy these conditions. In this study, the most important filter types are handled and a performance analysis between L, LCL and LLCL filter was implemented. Consequently, it is concluded that LLCL filter has higher performance and lower cost, on the condition that some risky points are considered.

Özet

Şebeke bağlantılı eviricilerde, şebekeye aktarılan akımların toplam harmonik bozunumunun %5’in altında olması gerekmektedir. Bu amaçla çıkış filtreleri kullanılmaktadır. Toplam harmonik bozunumundan başka filtrenin üzerindeki gerilim düşümü ve filtrenin reaktif güç tüketimi için de tasarım koşulları sağlanmalıdır. Bu koşulları sağlamak için çeşitli filtre tasarım yöntemleri literatürde sunulmuştur. Bu çalışmada, en önemli filtre tasarım yöntemleri ele alınmış ve L, LCL ile LLCL filtre tasarımları arasında bir performans analizi yapılmıştır. Sonuç olarak, LLCL filtrenin, bazı riskli noktalar dikkate alınmak şartıyla, daha yüksek performans ve daha düşük maliyet sağladığı ortaya çıkmıştır.
