RESUMO

This thesis presents the development of analytical methods for analysis of squirrel-cage induction generators connected to distribution systems. It was developed analytical methods for evaluation of the following technical issues: large-disturbance stability analysis of induction generators; small-disturbance stability analysis of induction generators; determination of optimum resistances employed by energization devices of induction generators and development of formulas to determine the short-circuit currents of induction generators during unbalanced faults. The analytical methods developed were validated by comparing the results obtained by the proposed formulas with those determined by computational simulations employing typical programs of analysis of power systems and/or experimental tests. The results showed that the proposed analytical methods are enough accurate to evaluate the behavior of the squirrel-cage induction generators, reducing the usually necessary effort for analysis by computational simulations
