Wind generators as compared to large heavy duty power generators

Wind turbine generators are different than conventional thermal turbine-generators both in the types of machines used as well as the type of application and environment in which the machines operate. The wind generator and its converter have several common configurations, rotor types, and operational duties that are not commonly encountered in large power plants. Those differences are discussed in regard to machine design aspects, such as winding insulation, as well as environmental factors and maintenance factors.
