Advantages of traditional relay protection
Generators: Protects against overload, loss of excitation, and synchronization errors. Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. As a result, in these low-inertia environments, conventional overcurrent and distance protection schemes are often ineffective, increasing the risk of mis-operation or operation failure and, in turn, di ectly compromising grid reliability. A protective relay is an electrical device designed to detect abnormal conditions, such as short circuits or overloads in power systems. It automatically triggers circuit breakers to isolate the faulty section, protecting equipment and ensuring safety.
