Análise teórico-experimental do gerador de indução trifásico diretamente conectado à rede de distribuição elétrica

Abstract

This paper presents an analysis study about the induction machine, operating as a generator directly connected to the electrical power grid. One of the main characteristics of the generator operation is to work in zones distinctly from its rated power, supplying a variety of loads with different demands of power. When working on the saturation region, the induction machine generates currents with distorted wave forms. Intending to analyze such distortions, an adequate computational modeling, considering the magnetic saturation effects is employed. Experimental tests were made with a real machine for theoretical-experimental confrontation purposes. For a wide band of operation and generate power, the currents, voltages, power and velocity are analyzed, revealing the operational characteristics of the generator induction machine.
