6 Automation for Power Grid NR s innovative smart substation solution realizes modern substation operation by using fiber optic network instead of conventional cable wiring and thereby reducing the workload and extending the substations operational period. It includes process level equipment such as electronic fiber CT/PT, merging units, intelligent control unit and local control panels, and also includes the PCS series protection and control devices like protective relays, disturbance recorders, automation systems, remote control systems and protection information systems. As shown in Figure 3, communications between each level are implemented by two independent networks: station bus and process bus. Station bus is used to transmit MMS, GOOSE interlocking and time synchronization information between station level and bay level. Process bus is used to deliver sampled value, GOOSE tripping commands and GPS synchronization information between devices at bay level and process level via IEC standard protocol. The use of Sampled Value(SV) makes current/voltage sampling at primary side easier and more reliable. Voltage and current signals are captured at primary side, converted to optic signals and transferred to protection and control devices via optic fibers. This can lower the requirement of transformer insulation and reduce the interference in the analog signals transmission.
