(1) Monitor the normal operation of the power system. When the protected power system component fails, the relay protection device of the component should quickly and accurately issue a trip command to the circuit breaker nearest to the faulty component, so that the faulty component can be interrupted from the power system in time, so as to minimize the damage to the power system component itself. Reduce the impact on the safe power supply of power system. When the failure of the system and equipment is enough to damage the equipment or endanger the safety of the power grid, the relay protection device can minimize the damage to the components of the power system itself and reduce the impact on the safe power supply of the power system. (such as: single-phase grounding, transformer light, heavy gas signal, transformer temperature rise too high).
②, the reaction of electrical equipment is not normal working condition, and according to the abnormal working condition and equipment operation and maintenance conditions of different signals, prompt the duty officer to take quick measures to restore it to normal as soon as possible, or automatically adjusted by the device, or those who continue to run will cause the accident of electrical equipment to be removed. The relay protection device that reflects abnormal operation allows a certain delay of action.
(3) Realize the automation and remote operation of the power system, as well as the automatic control of industrial production. Such as: automatic reclosing, standby power automatic input, remote control, telemetry, etc.
