Evaluation of the use of the frequency regulated conveyor drive

The article is devoted to modeling an induction motor when using direct start of the motor and control system with a frequency converter with an autonomous voltage inverter. The characteristic features for constructing and modeling complex electromechanical systems of the Simulink and SimPowerSystem applications, which are part of the Matlab application package, are highlighted and described. In the process of work, simulations of two different options for starting an induction motor were made: direct engine start from a three-phase voltage source; starting the engine using a frequency converter. This direction is also supplemented by a comparative analysis of the drive with and without a frequency converter.
