2. Doubly fed electric machine - Wikipedia

   en.wikipedia.org/wiki/Doubly_fed_electric_machine

   Doubly fed generator for wind turbine. Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large variable speed wind turbines, because wind speed can

3. Variable speed wind turbine - Wikipedia

   en.wikipedia.org/wiki/Variable_speed_wind_turbine

   For variable speed wind turbines, one of two types of generators can be used: a DFIG (doubly fed induction generator) or an FRC (fully rated converter). A DFIG generator draws reactive power from the transmission system; this can increase the vulnerability of a transmission system in the event of a failure.

6. Permanent magnet synchronous generator - Wikipedia

   en.wikipedia.org/wiki/Permanent_magnet...

   Synchronous generators are the majority source of commercial electrical energy. They are commonly used to convert the mechanical power output of steam turbines, gas turbines, reciprocating engines, and hydro turbines into electrical power for the grid. Some designs of wind turbines also use this generator type. In the majority of designs, the ...
