Abstract

Solar energy is a renewable energy source that has become increasingly popular in recent years as an electricity source. However, the availability of trained personnel to install rooftop solar panels is limited. This community service program was conducted to provide training in residential solar system installation for students from Dayah Mini Banda Aceh. The training took place in the Power Electronics and Renewable Energy Laboratory at Universitas Syiah Kuala, where theoretical training on renewable energy was combined with demonstrations of equipment and simulated installation practice. The modules included rail mounting, panel positioning, inverter connections, charge controller setup, and wiring in series and parallel. Students were guided by lecturers and assisted by engineering students who had already undergone training in this field. They exhibited great enthusiasm and completed all the stages of installation successfully. This program not only addresses the shortage of workers with such skills in the solar installation industry but also helps students from low-income families acquire these practical competencies that can lead to jobs or entrepreneurship within the ever-growing sector of renewable energy; thus reducing unemployment among their communities while supporting Indonesia's shift towards sustainable energy.

Abstract

Short circuit faults occur frequently on distribution lines. Such faults generate a fault current within a short interval and result in a momentary voltage drop, commonly known as a voltage sag. On a feeder, the short circuits that occur most often are single-phase-to-ground, two-phase, and three-phase faults. To determine the voltage sag on the line caused by a short circuit, it is necessary to analyze the short circuit fault current and voltage sag by assuming the fault point at 25%, 50%, 75%, and 100% of the total length of the BA 15 feeder. The voltage sag when a single-phase-to-ground short circuit occurs at 25%, 50%, 75%, and 100%, respectively, is 8663.68∠0° V, 5773.4∠0° V, 2886.87∠0° V, and 525.48∠0° V. When a two-phase short circuit occurs, the voltage sag is 19022.602∠0° V, 16637.035∠0° V, 12106.47∠0° V, and 11826.98∠0° V, while during a three-phase short circuit it is 5000∠-76.05° V, 10000∠-70.21° V, 15000∠67.05° V, and 18231.99∠24.29° V. This voltage sag disturbance can be corrected using a DVR, which injects the voltage required to restore normal conditions.
