The shift toward decentralized and renewable energy systems is reshaping how substations must operate. This whitepaper — jointly developed by Welotec and Westermo — provides a concise, practical overview of how IEC 61850 enables the transition from traditional copper-based substations to modern Digital Substations.
It explains the architecture of Process and Station Buses, outlines the requirements for real-time communication, and compares redundancy methods such as PRP and HSR. The paper also highlights the critical role of IEC 61850-3 and IEEE 1613-certified hardware in ensuring reliability under harsh substation conditions.
Finally, it showcases how the Welotec RSAPC Mk2 and Westermo’s substation-grade switches and RedBoxes together create a high-performance, future-proof foundation for the intelligent grid.
