- Coordinate protection with the network service provider where upstream circuit breakers clear transformer faults, including intertripping and anti-islanding.
- Design substation and plant control systems: bay controllers, interlocking,



local control cubicles and HMI.
- Define the SCADA architecture linking switchgear, RMUs, SUTs, battery/PCS controllers and the power plant controller.
- Design IEC 61850 station bus and process bus systems, redundant networks (RSTP, PRP/HSR) and time synchronisation (PTP/GPS).
- Produce schematics, wiring diagrams, cable schedules, panel layouts, IO lists and protection settings files.
