Interoperability Assessment of IEC 61850 Devices in a Multivendor Digital Substation

 Researchers at the Karlsruhe Institute of Technology (KIT) presented a great paper at the IEEE GPECOM, June 2024, in Budapest:

Interoperability Assessment of IEC 61850 Devices in a Multivendor Digital Substation

"The present paper investigates interoperability challenges in multivendor digital substations, focusing on vertical data exchange reliability and Precision Time Protocol synchronization amidst various implementations of the IEC 61850 standard. The state of the art is examined through an Interoperability Testing Framework that assesses communication issues and data exchange across different equipment. Utilizing a two-phase bottom-up and top-down approach within this framework yields an efficient system deployment, focusing on synchronization, data exchange reliability, and addressing variations in IEC 61850 implementations, alongside a systematic literature survey. Results indicate that the proposed top-down engineering process can mitigate interoperability issues, promising streamlined future deployments."
