Abstract
With digital communication technologies continuing to grow in performance and reliability, a fully digital substation automation system (SAS) with a sampled values based process bus has become a realisable prospect in the foreseeable future. This, however, demands additional work in engineering configurations and tightens the existing constraints on multi‐vendor interoperability, network performance and time synchronisation. As a result, detailed testing and validation of SASs prior to installation is paramount. Integrated testing is the most comprehensive approach to test a SAS, as it evaluates the performance of multiple aspects of the system simultaneously. Real‐time power system simulators can interface with multiple intelligent electronic devices in real‐time via IEC 61850 station and process buses, while accurately simulating the electrical substation. Hence, they possess the unique capability to carry out closed‐loop, integrated testing of SASs. This study presents a methodology to test a fully digital SAS using a real‐time power system simulator. Particular emphasis is given on carrying out integrated system testing of a SAS in a laboratory environment. Example test scenarios are provided to highlight the effectiveness of the proposed testing approach.

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
