Frenagem regenerativa em máquinas CC

Abstract

This course conclusion work aims to develop a methodology for research, analysis, simulation and assembly of a regenerative braking system using DC motors with independent excitation or permanent magnet, controlled by the armature from an AC network, having as actuator a Dual pulse converter operating with circulating current. The search for sustainable development and energy recovery in mechanical systems is increasing, from that on, theoretical studies on the subject discussed were discussed, as well as electronic techniques for driving the DC machine. A mathematical model was made, simulating and analyzing the results generated in the application of braking technology. These research and methodology guided the development of the experimental results, verifying the possibility of braking regeneration using the Dual Converter. From this study, the experiment was built and the tests verified that it is possible to confirm the power during the braking of the CC machine. The control system was properly realized in open loop, in this way the regenerated power can be even higher through a control technique.
