Digital Substation

With the development of protection, automation and communication technology, NR’s digital substation technologies offer a complete digitalized solution that fully connects the control room to the switchyard with optic fiber links. This proven solution reduces your capital investment, operational and maintenance costs. It also offers unmatched information integration, and provides better reliability and security for substations.

Digital Substation
  • IEC61850 Based Communication Network
    The baseline communication topology of NR’s Digital substation Solution consists of a process bus and a station bus. Other communication topologies, such as optical Point-to-Point network, are also supported. The process bus employs IEC 61850-9-2 Sampling Value, IEC 61850-8-1 GOOSE for time-critical message and IEEE 1588 protocols. The station bus employs IEC 61850-8-1 MMS, GOOSE message and SNTP protocols. All of devices are fully compatible with IEC61850 ed1&ed2.
  • True Optical Links
    Communications between equipment can be realized by fiber links in the entire substation. This unique and smart solution is suitable for newly constructed and refurbishment substations.
  • Reliable Electronic CTs/VTs
    NR Electric has pursued advanced research on electronic CTs and VTs to ensure maximum reliability and availability in the applications of metering and protection relays.
