51 Wind Turbine Generator Systems
52 Evolution of Wind Turbine Generator Systems FSIG wind turbines were applied to wind turbines as large as 1.5 MW. There are increasing difficulties in controlling drive train oscillations and limiting mechanical load. FSIG wind turbines have difficulties meeting the requirements of the Grid Codes. DFIG became increasingly common in large wind turbines where the benefits of limited variable-speed operation were required but at the reduced cost of controlling only a fraction of the output power. Slip rings are required on the generator roto and the air-gap of a wound rotor induction generator must be kept small. FPC overcomes these problems, but it is expensive
