Relay protection refers to the study of power system failures and abnormal conditions that endanger safe operation to explore the countermeasures of automatic measures against accidents. In the power system, if there is no failure in the primary system, but the protection is malfunctioning, it will affect the reliable power supply to users. If the heavy-load line malfunctions and trips, it may also cause system oscillation accidents and destroy the safe and stable operation of the system; if a short-circuit fault occurs in the primary system, but the protection refuses to operate, it will expand the scope of the accident and even damage the power equipment. In order to make the protection truly play a role in protecting and controlling the power system, the protection must be in a good operating state as a whole, so that the characteristics of all related components and equipment are excellent, the circuit wiring is correct, and the setting and action characteristics are correct, so the inspection quality of the protection must be strengthened.
