Abstract
Good electric power system must have good power quality, including small power losses and voltage value at all buses do not exceed the tolerance limit. The tolerable limit of allowable voltage value is between 0.95 to 1.05 per unit. In this research, the quality of Bosowa Cement Industry, Maros' power system will be improved by using capacitors banks. This research will focus on optimum capacitor location determination and size using Genetic Algorithm (GA) to enhance low voltage and minimize power losses. It presents a model for simultaneously allocating bank capacitors for reactive power compensation in power system with a significant amount of dynamic rotating machine load. This research conducts several simulation of power flow before and after installation, optimization of capacitor placement with different bus candidates, to determine the location, number and capacity of capacitor then its economic analysis. The selection of a voltage dropped bus as a candidate only requires 7.400 kVar of 73 capacitor bank units with the value of each capacitor bank 100 kVar which aims to improve the quality of power at Bosowa Cement Industry, Maros, which is installed on several buses. Installation of capacitors can reduce power losses in the system from 901 kW to 801 kW.
