Study of overcurrent and earth fault protection system by using PSS-Adept: article

This paper studies the protective relay setting and coordination using PSS-Adept. Faults and failures normally occur in power systems, which consequently require an auxiliary system that must take corrective action upon the occurrence of a fault. This auxiliary system is known as a protection system. Protection systems are sets of equipment designed to detect faults in the protected elements of the power systems, disconnect the faulted element, and re-establish the service. By utilizing the PSS-Adept software, this study evaluates the efficiency of relay coordination to ensure optimal grid reliability and minimize operational downtime during power system disturbances.
