In order to study the methods of controlling an asynchronous motor with a frequency converter of the SINAMICS S120 line from Siemens with the implementation of various types of load diagrams, a training stand was assembled and configured in the TIA Portal software. The load for the asynchronous motor was implemented using a synchronous motor, which was mechanically connected by a shaft. The stand includes the following elements: programmable logic controller CPU 1510SP-1 PN; communication processor CP 1542SP-1 for connecting SIMATIC S7-ET200SP to the Industrial Ethernet network; basic AC drive SINAMICS S120 CU320-2 PN; inverter control modules for asynchronous motors and synchronous DC 510-720 V, 2x4.8 kW; 2x9 A in the amount of 2 pcs.; asynchronous motor with a squirrel-cage rotor 0.37 kW, 1500 rpm; synchronous motor with permanent magnets 0.82 kW, 3000 rpm. The work solves the problem of developing a mathematical model with a scalar and vector control system with the possibility of comparative analysis of transient processes on a real electric drive.
