Application of Modbus to IEC61850 Gateway in an Energy Power Station

Published: 2026-05-14 10:57:54

A factory's energy power station is equipped with multiple power meters and temperature controllers. The requirement is to transmit realtime data—including line voltage, current, active power from the power meters, and temperature data from the temperature controllers—to the power management system. This enables the SCADA or host system to monitor field devices, manage operations, and perform data analysis.

 

A site survey confirmed that both the power meters and temperature controllers support the Modbus RTU protocol, and their communication ports are free for use. The host system, on the other hand, is an IEC61850 master station. To address this, WideIOT deployed industrial intelligent gateways to perform Modbus to IEC61850 conversion and Ethernet data collection, ensuring stable and reliable communication for power energy systems and providing digital support for energy management.

Key Features

The gateway features a builtin highperformance protocol parsing engine. It can simultaneously collect Modbus RTU data from multiple power meters and temperature controllers and map it into standard IEC61850 data formats. It supports various communication methods including 5G, 4G, WiFi, and Ethernet.

 

In the event of a network interruption or IEC61850 master station failure, the gateway automatically stores collected data in local storage. Once communication is restored, it resumes transmission with timestamps, ensuring no historical data is lost and maintaining data integrity and traceability.

 

A dedicated gateway management platform is provided, enabling remote configuration, firmware upgrades, data updates, and realtime message diagnostics. No onsite programming is required, which reduces maintenance costs and helps engineers quickly identify and resolve anomalies.

 

The gateway can be expanded to support additional energy devices using protocols such as DLT645, CJ188, and IEC101/103/104. It also supports upstream protocols including Modbus, MQTT, IEC104, and OPC UA, allowing connection to local host systems or cloud platforms.

 

The host system is capable of receiving and parsing all data, enabling advanced applications such as load analysis, energy consumption statistics, demand management, and trend forecasting. These capabilities help the factory achieve refined energy management, energy savings, and carbon reduction goals.
