Analisis Perbaikan Tegangan Jatuh Menggunakan Tap Changer Transformator Dan Penempatan Kapasitor Bank Pada Penyulang Dengan Genetic Algorithm

Abstract

Electricity demand in Indonesia is already increasing, as economic growth and high population. The effect of electrical energy will operate excessively, to meet the required demand. It can create problems such as an unauthorized tension drop, increased power loss in the channel and also result in an unbalanced load. One way to improve the voltage and power loss profiles is by adding a Tap Changer and Bank Capasitor. In this thesis included additional of Tap Changer and Bank Capacitor on the IEEE 33 Bus network system using Genetic Algorithm (GA) method to determine values, capacity and location of the Tap Changer and Capacitor Bank systems. From the simulation already done that the installation of 2 Tap Changers and 2 Capacitors of the Bank can improve the voltage profile of 21 buses that originally existed outside the standard IEEE became fully optimal. There is also a decrease in active power losses of 72 kW originally of 202,7 kW to 130,7 kW, and a decrease in reactive power losses of 41,8 kVar to 93,3 kVar.
