Real-Time Wavelet-Based Data Compression in Light of IEC61850 Communication Protocol
Bibliographic record
Abstract
This study addresses the problem of data compression in the context of IEC61850 communication protocol used in smart grids. The study presents a new approach based on wavelet compression that uses the predictor importance to identify the wavelet detail level that holds the salient features of the disturbance signal and then applies a hybrid threshold that includes both hard and soft thresholds to the wavelet details. The effectiveness of the proposed approach has been tested and evaluated and the results have shown that the proposed approach was very effective in increasing the compression ratio leading to reduction in the file sizes. Furthermore, the results of testing the proposed approach using a real-time digital simulator in the context of IEC61850 showed that the implementation of the proposed approach not only led to a significant reduction in the number of messages but also leads to a reduction in their sizes while maintaining a high-quality signal reconstruction following the compression process.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
