Proceedings of the Institute of Electrodynamics of the National Academy of Sciences of Ukraine| Zusammenfassung: | One of the important challenges of today is to ensure energy efficiency and improve the performance of the most common induction electric drives (IEDs) for production and lifting and handling machines. Increasing the overall control range and stable speed control in AEDs is often ensured by the use of pulse-key or phase-pulse control systems for the speed of rotation of the AD FR, in which the control is carried out in the rectified rotor current circuit. The presence in such schemes of a rotor winding voltage rectifier creates conditions for the use of the dynamic self-excitation braking (DSB) mode. The paper proposes a mathematical model of the AD FR in the DBS mode in the system of coordinate axes (d, q) fixed relative to the rotor, taking into account the saturation characteristics of the magnetic system of the machine. The model was tested by computer simulation using the capabilities of the Simulink Matlab package. The created model is of practical value; in the formation of energy-efficient braking modes of AEPs, it will allow analysing complex electromagnetic transients and reasonably choosing the structure and parameters of their electrical circuits.
