Technology options for utility grade electric power generation from wind

Four options of wind electric generator (WEG) technology have been studied and compared based on their estimated field performance. The electric generators considered are squirrel cage induction generator (IG), doubly wound cage IG, double output wound rotor IG and permanent magnet generator (PMG). The performance evaluation has been done by developing power flow models of the WEGs. The results highlight the relatively superior performance efficiency of WEGs employing doubly wound IG and double output IG.
