Abstract
This paper presents a real-time simulator for large power networks based on commercial-off-the-shelf products and the RT-LAB platform developed by Opal-RT Technologies Inc. This platform uses Pentium-, Xeon-, or Opteron-based PCs (multi-CPUs and/or dual-core configurations) or even Xilinx FPGA cards for computational engines, and infiniband communication fabric for fast inter-PC communication. The real-time PCs run under well-known operating systems QNX or RedHawk Linux, while the main control interface is either Simulink software from MathWorks or Lab VIEW software from National Instruments. The paper demonstrates the real-time simulation of a complete, single-pole, 12-pulse, HVDC system on a 2.2 GHz, dual-CPU, dual-core, Opteron PC with an under 15-microsecond time step. Also demonstrated are real-time simulations of complex power system devices like SVCs, STATCOMs, and more general power systems like the Kundur network. The paper also discusses the latest advances in hardware-in-the-loop simulation, including directly programming devices like a PMSM drive in an FPGA card. This feature is enabled in RT-LAB with the Xilinx System Generator, a Simulink blockset. Such FPGA targeting diminishes further the leap between prototype and production-type controller systems because an FPGA card can implement rapid control functions along with fast protection systems, like IGBT-current protection, of a real controller

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
