Abstract
Commutation failure is one of the most common failures that may lead to serious consequences in high-voltage direct current (HVdc) systems. Superconducting fault current limiters (SFCLs) have been proved effective to inhibit commutation failures. In this paper, different installation positions of SFCLs are compared through three proposed evaluation indexes. The position between ac and dc systems is proved to have the best performance, and the position at the end of dc line performs moderately but costs less. Then, methods for calculating the convergence resistance of the SFCL are recommended. The theoretical method can draw the lower limit of the resistance quickly and reduce simulation time drastically when SFCLs are installed between ac and dc systems. In addition, an improved structure is presented to ensure fast recovery of an SFCL, so that the system can be restored quickly when the fault disappears. Simulations are carried out on PSCAD/EMTDC against the CIGRE HVdc benchmark system to verify the validity of the proposed installation scheme.

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
