The ANALISIS SISTEM SINKRONISASI DAN DISTRIBUSI DAYA GENSET PADA PROYEK DKUT PK-19 JIIPE GRESIK

Universitas Muhammadiyah Gresik

Abstract

TThe DKUT PK-19 Infrastructure and Landscape Development Project at the JIIPE Gresik industrial area is
a vital Bank Indonesia project requiring reliable and continuous power supply. To ensure energy availability, PT
Jaya Teknik Indonesia (JTI) installed a backup power system consisting of two Mitsubishi generator units,
MGS1500CL and MGS1300R L50. This study aims to analyze the synchronization and power distribution system
between generators and their connection to the PLN grid. The research method includes field observation and
operational parameter measurements, such as voltage, current, and frequency during testing, synchronization, and
power distribution. Results indicate that synchronization between generators successfully maintains load balance
with current differences below 5% across phases. The applied three-phase four-wire (3Φ-4W) distribution system
effectively delivers power through the Main Distribution Panel (MDP) to subpanels throughout the project. The
automatic synchronization system (auto-synchronizer) enhances fuel efficiency and voltage stability.
