Monitoring and inspecting GOOSE and sample value signals in IEC 61850 protocol analysis for digital substations: a novel approach

Tóm tắt

This study explores a novel approach to the monitoring and inspecting of digital signals, specifically Generic Object Oriented Substation Event (GOOSE) and Sampled Value (SV). The core novelty of this research lies in proposing a blind-diagnostic and reverse-engineering methodology to reconstruct interlocking configuration directly from raw payloads on Wireshark platform without dependency on original Substation Configuration Description (SCD) files. The methodology's reliability and feasibility are tested via a Hardware-in-the-Loop (HIL) testbed with strict quantitative parameters. The findings empower engineers to fully control latency and interlocking configuration in scenarios where design documentation is absent, thereby contributing to significantly enhancing the operational reliability of contemporary power systems in the era of smart grid.
