Uma proposta de co-geração de energia elétrica utilizando um gerador de indução trifásico assimétrico conectado a uma rede monofásica

Abstract

This work presents a proposal of electric power co-generation using an asymmetrical three-phase induction generator connected to a single-phase source. In this way, a mathematical model is developed in the time domain that represents the asymmetrical generator, the three-phase load and the single-phase source. Still in this modelling, the winding space harmonics are included. For the asymmetrical three-phase induction generator of 2cv, are obtained the design parameters through simulations. A prototype of 2cv is tested, and the experimental results are conffonted with the theoretical results. Still based on the developed mathematical model, simulations are made in conditions of voltage sag and swell in the single-phase source. Aiming to show the possibility to design asymmetrical generators with value of usual power in practice, the design parameters of a 60cv machine are presented. Still, is made an analysis of the power flow of in the single-phase source for several conditions of operation of the 60cv asymmetrical generator.
