Power Quality Monitoring

Il problema

Unexplained trips, harmonics and voltage dips damage equipment, but the analysers that could explain them are only read locally after the event.

Panoramica della soluzione

MILESGO gateways collect data from power quality analysers, electricity meters, protection relays and bay controllers over Modbus RTU / Modbus TCP / IEC 61850, and deliver it to SCADA, the energy management system, SMS, email and messaging alarms as OPC UA / MQTT / BACnet/IP. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

power quality analysers
electricity meters
protection relays and bay controllers

Protocol path

Modbus RTU / Modbus TCP / IEC 61850 → OPC UA / MQTT / BACnet/IP

Implementation checklist for the project manager

Collect register maps and protocol documents from every equipment vendor early; a missing map is the most common delay.
Configure NTP so trends, alarms and meter readings carry consistent timestamps.
Record CT ratios, meter IDs and multipliers in the point table; wrong multipliers are the usual cause of billing errors.
Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
Confirm local storage so data survives network outages, and define the retention period.
Commission in read-only mode first; enable write / control points only after the client approves each one.

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

Architettura del sistema

Field layer: power quality analysers, electricity meters, protection relays and bay controllers, connected over Modbus RTU / Modbus TCP / IEC 61850. 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: SCADA, the energy management system, SMS, email and messaging alarms, which receives the data as OPC UA / MQTT / BACnet/IP. Remote access for maintenance runs over VPN rather than open internet ports.

Fasi di realizzazione

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.
