Abstract

The author assesses the steady-state and transient behavior of an induction generator (IG) driven by mini hydro or wind turbines under grid abnormalities, as encountered in practice. Behavior under varying input power typically observed in wind machines is also reported. A computer simulation study was undertaken, and results on a 220-kW hydro machine and 55-kW wind machine, indicating the effect of grid abnormalities and varying input power, are presented. Run-up, reswitching, and short-circuit transients of the wind-driven IG are analyzed. The dynamic modeling and computer simulation procedure are given. Relevant results are presented and discussed
