What this covers
- Automation architecture — bay level, station level and the interface to the control centre, with the redundancy each layer needs.
- Relay and IED integration — Siemens SIPROTEC, SEL, Schneider MiCOM and ABB Relion on one system.
- Station-wide interlocking — switching sequences, earth switch and isolator interlocks, and permissive logic that prevents an unsafe operation.
- Bay control units and RTUs — configuration, point mapping and telecontrol interfacing.
- Operator interface — station HMI with live single-line status, control with select-before-operate, and alarm management that does not bury the important events.
- Time synchronisation — SNTP and PTP, so sequence of events records across devices can actually be compared.
- Telecontrol protocols — IEC 60870-5-101 and -104 and DNP3 to the network operator, alongside IEC 61850 within the station.
What you receive
- Automation system architecture and network drawings
- Interlocking matrix and switching sequence documentation
- Device configuration files and signal point list
- Station HMI project with mimic and alarm configuration
- Integration test procedure and witnessed FAT record
Standards and references
Engineering follows IEC 61850 for station communications, IEC 60870-5 and DNP3 for telecontrol, and IEC 61936-1 for the installation, with the network operator's own interface specification taking precedence where one exists.
