State Grid Relay Protection No 21
Testing and commissioning a distance or impedance protection relay (21) involves ensuring the relay accurately measures the impedance to a fault and operates correctly to isolate the faulted section of the power system. A form of protection against faults on long-distance power lines is called distance. The global energy transition is ushering in a new era of power electronic-dominated grids (PEDGs), to complement the increase in the widespread integration of renewable sources like wind and solar. It is reshaping traditional grid architecture and making way for more flexible, efficient and. “21” is the ANSI/IEEE device number for the distance protection in a protective relaying methods. The relay measures V and I and calculates impedance Z as V/I. If Z falls within the zone setting, the relay conducts a trip (instant or. cteristic supervision: Add a reactance supervision.
