Field Experience for Passive Power Filter for Grid-Connected Solar Rooftop Applications at Industrial Plants

This paper presents the solution of harmonic problem that caused by solar rooftop installation. The Passive Power Filter System (PPFs) is recommended for solving harmonic problem which produced from non-linear loads such as AC drive, SMPS and solar inverter. The PPFs is designed to eliminate the harmonic in the electrical system, result in the voltage and current distortion are reduced and avoid resonance problem. Moreover, it helps to compensate the reactive power and improve the power factor. The characteristic of PPFs is analyzed based on the simple calculation by the KMITL program. In practical, the PPFs is suitable for low voltage system which connected to the grid. There is high performance in solving harmonic problems in the electrical system.
