Abstract

As technology develops, the rapid increase in PV capacity will affect the grid. This makes it important to determine the PV limit that can be injected into the grid defined as the PV Hosting Capacity (PVHC). In this paper, the author evaluates and analyses the impact of PV connections on medium voltage distribution lines (20kv) using ETAP 19.01 simulation. A medium voltage Grid with a capacity of 30MVA, has an industrial load varies from 650 kVA to 25 kVA with the total load capacity of 2225 KVA. The loads are supplied from two sources, grid and PV system. The simulation results state that the best of grid performance which provide the best losses and voltage condition when connecting 100% capacity of PV to the existing grid network is by setting the inverter power factor to 0.9. This setting will provide lowest power losses of 0,7 kW and improve the voltage value.

Abstract

The wood processing industry heavily relies on three-phase induction motors to drive high-power equipment such as chipper machines. One of the major challenges in operating these motors is the high inrush current during startup, which can destabilize the power system and accelerate equipment wear. This study aims to analyze the effectiveness of using a soft starter as a starting method for a 400kW induction motor in a chipper application. The research method is an experimental case study involving direct field observation and theoretical calculations of electrical parameters such as nominal current, current limiting, torque, and trip class. The observation results show that the actual starting current of 1,216.15 A remains below the calculated current limiting threshold of 1,575 A, while the trip class value of 2,835 A provides optimal protection. The use of a soft starter proves effective in reducing inrush current, maintaining voltage stability, and enhancing the reliability and efficiency of motor operation. This research supports the application of soft starters as a suitable solution for high-power motor starting in heavy industrial settings.

Abstract

Pemahaman dan kesadaran tentang pentingnya renewable energy harus ditanamkan sejak dini melalui Pendidikan formal. Sekolah Menengah Kejuruan (SMK), sebagai institusi Pendidikan vokasi memiliki peran strategis dalam menghasilkan lulusan yang siap kerja. SMK N 2 Solok merupakan salah satu sekolah menengah kejuruan yang memiliki potensi besar dalam mengintegrasikan konsep renewable energy. SMK N 2 Solok dipilih sebagai lokasi kegiatan karena memiliki jurusan Teknik Instalasi Tenaga Listrik yang relevan dengan pengembangan teknologi energi terbarukan serta didukung oleh fasilitas laboratorium yang memadai. Pelaksanaan program pengabdian masyarakat di SMKN 2 Solok berfokus pada peningkatan pemahaman siswa dan guru terhadap renewable energy. Dengan metode sosialisasi bentuk ceramah yang meliputi presentasi materi dan permainan simulasi integrasi renewable energy kedalam existing grid. Hasil evaluasi menyatakan bahwa, dari 25 responden, dimana 92% adalah siswa, 44% menyatakan sangat sesuai dan 48% diantaranya menyatakan sesuai topik dan materi sosialisasi dengan kebutuhan mitra.
