Processed model data and field-report summaries for a regulated semi-flow downhole power-generation system

This dataset contains the processed model data and field-report summary records underlying the figures and tables of the associated manuscript "Model-based design and field evaluation of a regulated semi-flow downhole power-generation system" (submitted to Systems Science & Control Engineering, Taylor & Francis). It includes the hydraulic-electromechanical model configuration and coefficients, computed rotor-speed envelopes, maximum-admissible-load thresholds, the resistance-torque calibration, a survey of representative telemetry power systems, and summary statistics from the SP-T rectifier/stabilizer and the generator operating-hours recorder. Files are provided as CSV plus a combined XLSX workbook, with a README describing contents, units, and provenance. These data are openly available under a CC BY 4.0 licence. Raw downhole service logs and detailed mechanical drawings contain commercially confidential equipment information and are not required to reproduce the analyses; they are therefore not included.
