How to Obtain Reliable Process Bus Time Synchronization Compliant with IEC 61850

The evolution of digital substations demands reliable, deterministic communication — and Bitstream S.A. provides tailored solutions. This presentation will show how to achieve precise time synchronization in IEC 61850-based architectures using the QUAZAR-700 monitoring probe and the HYPERION-500 as a time server. We will address synchronization accuracy, latency, jitter, and cybersecurity, highlighting how our solutions overcome challenges like jamming. Guidance on PTP profile selection, redundant architectures (PRP/HSR), and GNSS time sources will be provided.
