Abstract
Due to its unique topology, the Modular Multilevel STATCOM has many advantages but requires a sophisticated controller and puts higher requirements on simulation tools. To simulate the STATCOM in real-time is preferable because it enables hardware-in-the-loop test of the system in various scenarios including extreme fault conditions, which cannot be tested on a real STATCOM. This paper presents a model of full-bridge sub-module which enables fast offline and real-time simulation of the STATCOM. A control scheme with a new submodule capacitor voltage balancing method is also proposed in this paper. The model and the controller are investigated for different operating conditions. Implemented in a real-time simulator, the model can be simulated in real time at a time step of 20 μs, 131 times faster than its reference model. As demonstrated by the results, the proposed control scheme is effective and robust.

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
