Capacitor Banks and its Effect on Power System with High Harmonics Loads

In order to utilize the electrical system effectively, industries are installing capacitor bank in their power circuit. The use of power electronic devices has increased in recent years which resulted in an increase of harmonics in the power system. This has urged the need to study, understand the behavior of harmonics in different conditions. This paper assesses the importance of power factor in electrical system and later explained how harmonics generated; its effect on the power system and how to reduce (mitigate) the effect of harmonics. At last effect of capacitor bank on power system harmonics were explained and concluded the result with the help of a case study which shows a real-time example with the help of waveform showing percentage current and voltage harmonic distortion variation at incomer with respect to APFC ON/OFF status and harmonic reduction techniques.
