Abstract
Mathematical models for the analysis of processes during start-up and steady-state operation of three-phase asynchronous motors with short-circuit rotor with capacitive reactive power compensation have been developed. Based on them, algorithms have been developed to determine the capacitance of capacitors in these modes and to investigate them for self-oscillation and resonance. The developed algorithms are based on a mathematical model of an asynchronous motor, which takes into account the saturation of the magnetic circuit and the phenomenon of the skin effect in the rotor bars. The problem is solved in orthogonal coordinates.
