Hybrid Parametric Average-Value/Detailed Modeling of Classic HVDC Systems
Bibliographic record
Abstract
Switching models of power-electronic converters offer high accuracy for electromagnetic transient (EMT) simulations. However, they require small time-steps which impose a computational burden, especially for the simulation of large systems. Recently, a hybrid parametric average-value/detailed model (HPAVM) has been developed for line-commutated rectifiers which can reconstruct the ac and dc waveforms consistent with the switching models while allowing large time-steps for simulations. In this paper, first, the HPAVM formulation is extended to line-commutated inverters. Thereafter, the numerical performance of the proposed hybrid parametric average-value/detailed modeling technique is investigated on a classic line-commutated-based HVDC system. It is verified that the proposed HPAVM can be superior compared to switching models of HVDC systems by allowing simulations with large time-steps while maintaining acceptable accuracy.

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.
