Substation Protocol Gateway

ปัญหา

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.

ภาพรวมโซลูชัน

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

สถาปัตยกรรมระบบ

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.

ขั้นตอนการส่งมอบ

  1. 1

    Site survey and point list

    Inventory devices, protocols, register maps, panel space, power and network paths.

  2. 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. 3

    Configuration and FAT

    Build the gateway configuration off site, simulate it and test against the signed point table.

  4. 4

    Installation and wiring

    Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.

  5. 5

    SAT and alarm tests

    Verify values against local readings, test every alarm and command end to end.

  6. 6

    Handover and support

    Hand over configuration backups, point table and as-built documents; train operators.

คุณค่าสำหรับลูกค้า

  • 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
