Abstract

Peralatan listrik seperti pompa air, televisi, mesin cuci, kipas angin, lemari es dan lampu merupakan kebutuhan rumah tangga yang tidak dapat dipisahkan dari kehidupan manusia saat ini sebagai alat bantu dalam kehidupan sehari-hari. Kebiasaan membiarkan peralatan listrik menyala saat tidak digunakan merupakan salah satu faktor penyebab pemborosan energi listrik. Tujuan dari penelitian ini adalah untuk membuat sebuah sistem yang dapat memantau data konsumsi energi secara real time dan dapat ditampilkan dalam bentuk grafik serta sistem yang dapat mengontrol penggunaan energi listrik jarak jauh melalui halaman web. Sistem yang dirancang menggunakan sensor PZEM-004T untuk mengukur besaran yang dibutuhkan, pendeteksi arus sebagai, relay sebagai pengontrol beban melalui halaman web, Arduino Uno sebagai pembaca dan pengirim data, Raspberry Pi sebagai pengolah dan halaman web sebagai antarmuka. Hasil dari penelitian ini secara keseluruhan sistem kontrol dan monitor bekerja sesuai dengan desain. Sebuah sistem miniatur untuk mengendalikan beban listrik rumah tangga melalui halaman web dapat diterapkan. Nilai Arus, Tegangan dan Daya dapat ditampilkan di halaman situs web secara real time. Nilai Arus, Tegangan dan Daya dapat ditampilkan dalam bentuk grafik data harian dan bulanan di halaman web.

Abstract

All operational activities at the El Tari Kupang airport in meeting their electricity needs are obtained from the electricity supply from PLN. Fulfilling the electricity needs in the airport building is expected to be able to serve lighting loads, motor loads and other loads without any disturbance. The existence of disturbances such as short circuits in the electric power system can cause problems such as damage to electrical equipment and the emergence of power outages. Therefore, problems that arise like this require an analytical study to determine the short-circuit current that will occur while reducing the consequences. The purpose of this study is to determine the magnitude of the short-circuit fault current and determine the severing capacity of a power breaker in protecting the short-circuit fault current, in the event of a short-circuit fault in the low-voltage panel. Short circuit simulation results with ETAP 12.6.0 will be compared with manual calculations based on positive, negative and zero sequence impedance values from the fault location point. The results of this study note that the smallest short-circuit fault current is a 1-phase short-circuit fault to ground, with a fault current of 4.82 kA on the Switchgear 2 bus. The largest short-circuit fault current is a 3-phase short-circuit fault, with a fault current of 9 .45 kA on Switchgear 1&2 buses. Determination of the power breaker capacity on the low-voltage panel, the results of the circuit breaker (CB) breaking capacity on Bus Switchgear 1 the breaking capacity value is 10,875 kA, on Bus Switchgear 2 the breaking capacity value is 8.67 kA and on Bus Switchgear 1 & 2 the value its breaking capacity is 14,175 kA.

Abstract

Based on the 2021-2030 RUPTL, the addition of PLTU Timor 1 (2 × 50 MW) to the Timor system is carried out because electricity demand continues to increase. Therefore, a transient stability study is needed, to determine the reliability of the system when a disturbance occurs. By utilizing the Time Domain Simulation (TDS) method, the research was conducted by simulating generator outage and 3 phase short circuit to study the frequency stability of the Timor system. From the simulation results, generator outage has a major influence on system frequency stability, especially simulated at PLTU Timor 1 unit 1. The disturbance caused a decrease in the lowest frequency reaching 49.61 Hz so that it was not within the safe operating limits according to the operating guidelines for the Timor electricity system. For this reason, Manual Load Shedding (MLS) and the addition of generators at PLTD Cogindo and PLTMG Kupang Peaker are required. The action is carried out by paying attention to the rate of change of the next frequency. As for the 3 phase short circuit disturbance on one of the Bolok - Maulafa lines, the frequency increased to 50.06 Hz after the disturbance which is still within safe operating limits.
