Compatibility
PCS-9700 automation system is completely compatible with the IEC61850 standard and has passed the IEC61850 conformance test, obtaining the level A certification issued by KEMA. NR has established its own IEC61850 level B test laboratory to confirm the standard compliance for all NR products.
NR IEDs support IEC61850-9-2 standard and process level Generic Object Oriented Substation Event (GOOSE) messages. Compared to conventional substations, the process bus based on optical fiber is used to replace cable connections between IEDs. Therefore, project construction time and cost can be reduced significantly.
