What this covers
- System architecture — station bus and process bus topology, redundancy (PRP and HSR), and where a digital scheme is and is not the right answer.
- Data model design — logical devices, logical nodes, data objects and datasets structured so the system is maintainable by the next engineer.
- SCL engineering — ICD, IID, SCD and CID files and the configuration workflow that keeps them consistent.
- GOOSE scheme design — publisher and subscriber mapping, dataset definition, transmission timing and subscription supervision.
- Sampled values — merging unit integration and the timing and synchronisation requirements that come with it.
- Multi-vendor interoperability — conformance checking and resolving the mismatches that appear when relays from different manufacturers share a bus.
- Migration from hardwired — staged conversion of an in-service installation, running both signalling methods in parallel through the transition.
- Testing — GOOSE trip verification, subscription loss behaviour and end-to-end scheme proving.
What you receive
- System architecture drawing and network topology
- SCD file and per-device configuration files
- GOOSE mapping tables and dataset definitions
- Interoperability and conformance assessment
- Commissioning and test procedures specific to the station bus
Standards and references
Work is carried out to the IEC 61850 series — including 61850-6 for SCL, 61850-7 for the data model and 61850-8-1 and 9-2 for GOOSE and sampled values — alongside IEC 60255 for the relays themselves.
