A New Approach to Calculate the Ionized Field of HVDC Transmission Lines in the Space and on the Earth Surface
Bibliographic record
Abstract
Corona discharge is a common phenomenon in high voltage transmission lines. The corona space charge arising from HVDC transmission lines is much more significant than that from HVAC lines due to the extended distribution of the space charge, which greatly influences the electric field strength on the ground and in space. A new iterative method has been developed to solve Poisson's equation for HVDC line systems, accounting for the presence of space charge. The electric field strength can be calculated in the space around the HVDC transmission lines or on the ground. The system can be in homopolar, bipolar or hybrid mode, and can include sky wires or non-corona conductors. The conductors in the bundles are treated individually. The treatment accounts for the different corona onset gradient of positive and negative conductors and for ion recombination in the bipolar zones. Also, the positive and negative ions can possess different mobilities.

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.
