PETRONAS - Customer Case Study

PETRONAS RAPID project is the largest oil & gas refinery and petrochemical plant in Malaysia which is powered by a 1200MW utilities plant and connected to a 275kV Grid supply. The integrated ETAP model for the RAPID complex reached up to 5000 buses that consist of various distribution voltages from 400V up to 275kV. Protection Coordination evaluation study for the RAPID complex was performed using “PD Sequence-of-Operation” to identify abnormal relay behavior, which may not be observed in the conventional TCC curve.
