## 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.
