BSR Trials Power Monitoring System at Dung Quất Refinery
BSR has trialled an in-house power data monitoring system at the SS7 substation of Dung Quất Refinery, connecting 13 relays. After about a month of continuous operation, measurement data updated in under two seconds. The company plans to improve the system and gradually expand it to other substations at the refinery.
Vietnam’s Binh Son Refining and Petrochemical (BSR) trialled its in-house power data monitoring system at the SS7 substation of Dung Quất Refinery. It connected 13 REF542+ relays serving 6.6 kV and 0.4 kV electrical cabinets. After about a month of continuous operation, the system initially met the trial requirements.

The refinery’s existing smart relays can provide measurement data, equipment status, alerts and operating event records. However, limitations in the central electrical monitoring system’s connection protocols, configuration and data catalogue have prevented full use of this information. BSR’s technical team therefore developed an independent data collection system that automatically retrieves data via HTTP through the relays’ existing Ethernet connections and web interface. Nearly 350 REF542+ relays are in use at the refinery.
The new system can collect, organize, store and display data, allowing operators to check equipment status, review alerts and export reports. It also has an initial capability to issue threshold-based alerts. It provides supplementary monitoring only: it does not issue commands to close circuits or cut power, or change the relays’ protection settings.

During the trial, measurement data updated in under two seconds, while equipment status data updated approximately every 0.46 to 1 second. The system can detect a connection interruption and resume data collection when the connection is restored.
BSR power systems expert Đoàn Nguyễn Quốc Hùng said the trial results provide a basis for expanding the system to all 13 substations at the refinery. The team also plans to connect other relay models and smart devices, and gradually explore maintenance based on equipment condition and AI-assisted diagnostics.
