Substation Protocol Gateway
Bài toán
Private substations must report to the utility over IEC 104 or IEC 61850, but the installed meters and relays only speak Modbus, and a full substation automation upgrade is out of budget.
Tổng quan giải pháp
MILESGO gateways collect data from protection relays and bay controllers, electricity meters, transformer temperature and tap monitors, run/stop and fault dry contacts over Modbus RTU / Modbus TCP / DL/T 645, and deliver it to the utility SCADA (IEC 104 / IEC 61850), SCADA as IEC 60870-5-104 / IEC 61850 / OPC UA. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.
Typical scope
- protection relays and bay controllers
- electricity meters
- transformer temperature and tap monitors
- run/stop and fault dry contacts
Protocol path
Modbus RTU / Modbus TCP / DL/T 645 → IEC 60870-5-104 / IEC 61850 / OPC UA
Implementation checklist for the project manager
- Obtain SCL/ICD files or the IEC 104 point list from the utility early, and agree which signals are monitored and which are controlled.
- Configure NTP so trends, alarms and meter readings carry consistent timestamps.
- Commission in read-only mode first; enable write / control points only after the client approves each one.
- Keep OT networks segregated and use VPN for remote access instead of opening ports to the internet.
- Build and simulate the configuration off site (FAT) before installation to shorten time on site.
- Confirm the authority’s reporting requirements and data formats at the start of the project.
Project deliverables
- Signed point table and protocol mapping
- Gateway configuration files and backups
- IP address plan and network drawing
- FAT and SAT test records
- As-built documentation and operator training
Kiến trúc hệ thống
Field layer: protection relays and bay controllers, electricity meters, transformer temperature and tap monitors, run/stop and fault dry contacts, connected over Modbus RTU / Modbus TCP / DL/T 645. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: the utility SCADA (IEC 104 / IEC 61850), SCADA, which receives the data as IEC 60870-5-104 / IEC 61850 / OPC UA. Remote access for maintenance runs over VPN rather than open internet ports.

Các bước triển khai
- 1
Site survey and point list
Inventory devices, protocols, register maps, panel space, power and network paths.
- 2
Design and point table sign-off
Map every point to the target protocol and system; agree it with the client and the upper-system contractor.
- 3
Configuration and FAT
Build the gateway configuration off site, simulate it and test against the signed point table.
- 4
Installation and wiring
Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.
- 5
SAT and alarm tests
Verify values against local readings, test every alarm and command end to end.
- 6
Handover and support
Hand over configuration backups, point table and as-built documents; train operators.
Giá trị cho khách hàng
- New equipment integrated by configuration, not custom driver development
- Open interfaces (BACnet, Modbus, OPC UA, MQTT, HTTP) avoid lock-in to one vendor
- Timestamped records for compliance and reporting
- Monitoring added without changing existing control programs
