Abstract

Interkoneksi sistem Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) dapat terjadi keadaan tidak normal karena terjadi gangguan pada satu titik. Gangguan yang terjadi berupa hubung pendek fasa tunggal ke tanah, antar fasa, ganda fasa ke tanah dan tiga fasa ke tanah. Nilai arus gangguan hubung pendek yang berbeda dapat digunakan untuk identifikasi arus gangguan dalam penetapan setting dan rating alat proteksi arus lebih. Penyelesaian arus gangguan hubung pendek dengan menggunakan teknik impedansi urutan dan rangkaian ekivalen berdasarkan jenis gangguan yang terjadi. Aplikasi simulasi gangguan hubung pendek dengan software ETAP 12.6 pada interkoneksi sistem 6 bus unit PLTMH, 6 bus beban, 12 saluran total kapasitas terpasang 234,5 kVA atau 187,6 kW, 3 Phasa 400 V 50 Hz di Durian Tibarau Pasaman Barat. Studi kasus titik gangguan terjadi pada bus 33 PLTMH Kampung Sejati didapat hasil arus gangguan fasa tunggal a ke tanah 718 A, arus gangguan antar fasa b-c 537 A, arus gangguan ganda fasa b-c ke tanah 835 A, Arus gangguan tiga fasa 609 A dan arus gangguan terbesar 1.564 A.

Abstract

APIO is a fish drying equipment that utilizes sunlight which is converted into electrical energy using a solar power plant. This dryer works automatically using a control system that can control temperature and weight in predetermined settings. APIO designed in the form of a closed box with a heater and fan using a battery as an energy source. APIO uses a load cell and thermocouple as control input using an Arduino microcontroller and regulates the heat temperature in the box between 40-50?C. This tool was tested in the Pasie Nan Tigo Padang, Sumatra Barat. APIO tested using the Arduino uno control at night from 23:00 to 03:15 using fish weighing 5108 grams, data collection was carried out once for 15 minutes for 18 times. The average heater temperature was 32.71?C and the outside temperature was 25?C. The heater voltage was 11.33 V and the heater current was 36.02 A with clear weather conditions. The test results showed a decrease in fish weight to 4208 grams dry. Day time tested from 13:00 to 15:15 using fish weighing 1012 grams, taking data once for 15 minutes for 10 times the average heater temperature is 43.85?C, outside temperature is 30?C and fish weight reaches 208 grams dry.
