Abstract
The installation of the 600 kVar automatic capacitor bank in the 3.75 MVA PBI Dreyer substation significantly increases the overall system power factor. Two weeks after the installation, it was found that the capacitor bank failed. The study focuses on the cause of failure of the capacitor bank and offers a possible solution to avoid it from happening again at the PBI Dreyer Substation. IEEE Standard 519-2014 is used to evaluate the total current and voltage harmonic distortion measured by the Fluke power equality analyzer to determine the possible cause of failure of the capacitor bank. After carefully analyzing the data, harmonic resonance occurrence at the 3rd harmonic level is identified. The installation of Eaton single tuned passive harmonive filter with tuning order of 2.67 solves the problem regarding the harmonic resonance occurrence in the system, reduces the current THD from 27.59 to 14.17 voltage THD from 11.55 to 4.92 - which passes the IEEE Standard 519-2014. The filter also maintains the overall system power factor above 0.8, and is commercially available and cheaper compared to the other types of harmonic filters in the market.
