Abstract

Priok Power Generation Unit (PGU) is a combined cycle power plant (CCPP) which is one of the national vital objects with a generating capacity of 2,723 MW which functions as a load follower and Peaker in the electricity network system. This study aims to look at the environmental impact performance resulting from plant operating patterns January-December in 2020 and 2022, which was carried out using the life cycle assessment (LCA) method with SimaPro. The method life cycle impact assessment uses the ReCipe and CML IA baseline methods. The purpose of this comparison is to see improvements in the environmental performance of generating units to support sustainability. The results of this study show that there has been a change in the results of the environmental impact assessment in the Green House Gases (GHG) and Land Use Change (LUC) are the impact categories with the most significant reduction, namely more than 90%. Meanwhile, water footprints are the only impact that experiences an increase in environmental impacts during the 2020 operating period compared to the 2022 operating period.

Abstract

System Pressure has a vital role to control the pressure of the header gas output from the fuel gas compressor which distributed to each Gas Turbine (GT) as the main supply of fuel for the operating needs of the gas turbine. On June 10, 2021, there was a disruption in the fuel gas compressor caused by a malfunction in the pressure system due to an abnormal voltage supply to the pressure transmitter which resulted in the Priok Power Generation block 3 experiencing a blackout. The purpose of this study is to prevent system failure by making modifications in the form of implementing redundancy power supply modules. The conclusion from the results of the modification shows that there has never been a recurrence of the incident since it was installed for the redundancy power supply modules of the pressure Fuel Gas Compressor (FGC) system. The implementation of the module can prevent blackouts, increase system reliability number 0.995, and effective mean time to failures (MTTF) of system 35,700,000 hours. The modification design using switch ensures continuous power without interruption.
