Abstract

This study presents capacitor installation to reduced losses line, moreover improve voltage profile and power factor improvement. Capacitor optimization installed using modified backward forward sweep with the result that installation point and capacity appropriate. The modified backward-forward sweep have been tested on 15 BUS Kota Calang 20 kV feeder distribution, Aceh Barat. Initial simulation of feeder was result 0,85 kW line losses with 19,9753 minimum voltage. After capacitor installation on BUS 4, BUS 6, BUS 8 and BUS 13, the minimum losses line is reduced to 0,66 kW.

Abstract

Currently there are several tools that can be used for the process of measuring vertical and horizontal distances in one tool, but the process of use is still difficult for the layman to use. The main objective of this final project is to design vertical and horizontal measurement tools with 2 sensors for the horizontal and vertical measurement process into 1 tool only to make it easier for the layman to use as well. This tool is equipped with Incremental rotary encoder as horizontal distance meter, Infrared sensor as vertical distance meter, and seven segment as measurement data viewer by Incremental rotary encoder and Infrared in centimeter(cm)

Abstract

Design and simulation Multilevel  inverter three-phase  fifteen-level in this research using modulation technics of sinusoidal pulse width modulation (SPWM) in which input voltage sources that used was arranged as symetrical and separate for each phase by using free DC source in form of battery 12 Volt, 24 Volt, and 48 Volt as well as uses seven MOSFETs for switching in each phase. To produce fifteen levels, it can be done by using a combination method of battery arrangement by activating the MOSFET switching circuit according to the results of the comparison between the reference wave in the form of a three-phase sinusoidal wave and the carrier wave in the form of a free DC source by using SPWM modulation circuits. SPWM modulation circuits15level in this research was constructed by using an Op-Amp as a comparator, AND, NOT and OR gates as well as several other electronic components.The H-Bridge circuits is used to reverse the direction of the electric current so that it can to produce alternating current on the load side which is resistive and arranged in a star connection (Y), by using the PSIM simulation program, the THD value that produced  for each phase was relatively the same at 5.6%.
