What is ROCOF Protection Relay Principles about?

The document discusses the rate of change of frequency (ROCOF) protection df/dt working principle. ROCOF relays measure the rate of change of system frequency following a disturbance like loss of generation. This allows corrective actions like load shedding to be initiated earlier than waiting for frequency to dip below safety thresholds. The relay calculates df/dt by taking the difference between two successive frequency measurements averaged over three cycles. It can then trip circuit breakers and disconn
