Abstract
To achieve interoperability among multi-vendor substation automation devices, international electro-technical commission (IEC) has published IEC 61850 standard for communication networks within power substations. This standard specifies the communication systems based on Ethernet networks for the substation automation systems (SAS). Ethernet provides flexibility in terms of configuring various architectures with the help of Ethernet switches. However, the reliability and availability of the applicable Ethernet architectures need to be analyzed before they are implemented for critical applications in substations. This paper presents the reliability and availability evaluation of the practical Ethernet switch architectures using reliability block diagram (RBD) approach. The reliability block diagrams have been built for the intra-bay and inter-bay communications considering a typical transmission substation. Further, the reliability and availability of the practical Ethernet architectures have been compared and some suggestions have been made using the final results.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
