Abstract

Thetitle of this project is 'Studyand analysis of power factor improvement and the relationship with harmonics'. In industrial practice, it is iniportant to maintain the power factor of the power system to a certain level to ensure that thepower can be delivered to the system efficiently. Capacitor banks have been a conventional method of improving the low power factor problems. Power in AC circuits can be divided into three components namely active power, reactive power and apparent power. The power factor is defined as ratio of the effective to the apparent power. The harmonics distortion occurs when the signals is having the frequency components that is an integral multiple of me fundamental. The project execution consists of procedure identification, research and study, case study simulation and analysis of the project The project research and study is carried out to understand the principle andthe problem related to the power factor andharmonics. Simulation was carried out show the power factor improvement impact on the system andalso its relationship with harmonics. Tanjung Langsat Port project have beenselected to be analyzed and studied. From the study, it is found out mat the insertion of capacitor banks will compensates for the reactive power of the system and thus improving the power factor. Consequently, the improvement of power factor will reduce the system losses. The insertion of the capacitor will introduce harmonics resonance in the network. From the simulation, it is noted that as the capacitor kVAR value is increased, the resonance will occur at lower frequency. Harmonics distortions analysis at eachbusbar shows matthe Total Harmonic Distortions (THD) is highest when the injection sources areplaced atbothHVbusandLV bus. Finally the conclusion will summarize about the project and also the importance of considering the harmonics when installing the power capacitor to correct thepower factor.
