Análise energética de um motor de indução com frenagem regenerativa

Abstract

The industrial sector is responsible for approximately one third of the Brazilian electricity consumption, in view of the growing increase in energy demand, associat ed to environmental problems that make it difficult to generate electricity, it becomes necessary to seek equipment with greater efficiency to mitigate this condition. This work presents an energy analysis of a three-phase induction motor driven by a conventional frequency inverter and equipment equipped with regenerative braking technology. The research is based on the implementation of the two systems using MATLAB/Simulink, being the present study classified as of basic application, with exploratory objective and quantitative approach, having as research method the use of modeling and simulation. It was verified that in loads with high torque, the energy generated during the motor brake process can be reused and returned to the power supply, observing the losses of electrical energy in the industry, brought useful and environmental.
