Исследование переходных процессов при пуске синхронного электрического двигателя на базе замкнутой системы регулирования

Abstract

When designing systems starting of synchronous motors it is necessary to solve the problems associated with the development of adequate mathematical models of the engine, evaluation and selection of the most suitable for a particular sluca the method of forming the output forms of the curves of current and voltage to pulse width converter, the synthesis system of regulation and analysis of transient processes in electrical complex managed start-up. In work the analysis of transients, control of starting of synchronous motor using a closed system of regulation based on the model of the PWM Converter and the mathematical model of the synchronous motor constructed in the coordinates of the stator current and stator flux linkage. Also shows graphs of power consumption in the system with trapezoidal phase voltage and in the system with a sinusoidal phase voltage.
