Simulación y automatización de los sistemas variadores de velocidad para motores de corriente alterna

Abstract

The present project focuses on the control of the speed of the machine and the simulation of it, the programmable logic controllers that send the data in real time to the device that executes the supervision and control of the induction motor. As communication protocols, an Ethernet and Modbus industrial network was used, with communication system (Master - Slave) between two programmable automata and between a programmable automaton with the variable speed drive. The program WinCC RT Advanced and TIA Portal were used for the simulation, which allowed observing the characteristic curves of the economic changes that occur in the motor of the current by varying the frequency and speed of the computer simulation interface. of the automated didactic case Vacuum tests were carried out, with the rotor blocked and voltage injection test in direct current, with the results obtained from these tests the equivalent modeling and control of the asynchronous motor was achieved.
