Rail Power Substation Networking and Computing (IEC 61850)

Overview

Rail substations often involve primary and secondary equipment from different vendors, regions, and technical standards. IEC 61850 provides a common communication framework that streamlines data exchange between intelligent electronic devices (IEDs), station-level systems, bay-level devices, and process-level equipment. This improves interoperability, simplifies system integration, and supports future upgrades in railway power infrastructure.

Solution

Moxa’s solution supports IEC 61850 rail substation communication using industrial computers and Ethernet switches designed for station bus and process bus networking. With PRP-based redundancy, the network can maintain continuous communication even if one communication path fails. This helps rail operators improve reliability, reduce downtime, and build scalable substation systems that can adapt to future communication and application requirements.
