Relay protection automation (RPA) combines protection relays, control devices, and communication systems to monitor electrical network parameters such as current, voltage, and resistance, and to detect abnormal conditions like short circuits, overcurrent, or voltage deviations . When a fault occurs, RPA automatically triggers circuit breakers to disconnect the damaged section, preventing further damage and minimizing disruption to the rest of the network .
Modern RPA systems use multidimensional algorithms and machine learning techniques to recognize complex fault patterns and emergency modes, improving sensitivity and reliability . Intelligent electronic devices (IEDs) in digital substations implement these algorithms to enhance protection and automation capabilities .
