Field Experience Hybrid Power Filter for Power Quality Improvement in Industrial Plants

This paper presents a simple of harmonic filters design to minimize harmonic distortion caused by a harmonic source such as power electronic device. To avoid problem caused by the harmonics producing power electronic devices, the Hybrid Power Filters System (HPFs) are presented. The analysis includes the basic principles of harmonic filter. Passive Power Filter (PPF) can be designed by the KMITL Program. Surplus harmonic can be removed by active power filter(APF). The major objectives in the study are to improve the power factor, to reduced current and voltage distortion and to reduce resonance problems at a system. The results show that the HFs are a very appropriate solution for most typical harmonic problems and power factor correction for improvement in industrial plants.
