| Summary: | One of the indicators used to quantify the efficiency of electricity was the power factor. The index began with 0 and reached up to 1. The closer the value to 1 will indicate better power quality and higher efficiency for the electricity power network system. Due to a facility's weak power factor, utility is required to increase its producing and transmission capacity. One of the solutions to improve power factor is by adding a capacitor banks in the system. This project focused on the effect of install or adding capacitor banks into the electrical power system network in term of power factor, harmonic distortion and power losses. Harmonics in the power system are one of the most significant contributors to poor power quality and reliability. This has become a big concern in the power quality problem, and harmonic analysis is required to study in the modelling of components in order to reduce or eliminate the harmonic currents and voltages. In this project, capacitor banks have been added into the power system and harmonic analysis has been performed using ETAP software in details. To analyze the effect of harmonic current, Harmonic Load Flow analysis was performed and harmonic distortion identified. To eliminate this harmonic distortion, the use of single tunes filter of series reactor with capacitor bank are studied. The study shows the insertion of the capacitor banks will compensating for the low power factor however the harmonic resonance occurs thus increase the THD level. The THD level will decrease when the harmonic filter is install. This shows that the electricity can be transmitted efficiently to the system. |
