Modelación híbrida electro-térmica de máquinas de inducción mediante ATP-EMTP

Abstract

This thesis develops a hybrid electro-thermal model of a three-phase induction machine implemented in ATP-EMTP/ATPDraw. The electrical model uses Voltage Behind Reactance (VBR), and a second-order thermal model estimates stator and rotor temperatures. Computed currents and losses drive the thermal network and, in turn, temperature updates T-dependent electrical parameters, providing bidirectional feedback. Coupling exchanges variables each simulation step to keep electrical and thermal states consistent. The model is assessed under constant load and variable load profiles, analyzing dynamic currents, losses, temperatures, and equivalent resistance. Results confirm the approach is suitable for studying dynamic operating regimes and supporting performance and thermal protection analysis.
