 Wind Turbine Generators
Wind turbine generators are a bit unusual, compared to other generating units you ordinarily find attached to the electrical grid.
If you connected (or disconnected) a large wind turbine generator to the grid by flicking an ordinary switch, you would be quite likely to damage both the generator, the gearbox and the current in the grid in the neighbourhood.
Wind turbines may be designed with either synchronous or asynchronous generators, and with various forms of direct or indirect grid connection of the generator.

Wind resources are characterized by wind-power density classes, ranging from class 1 (the lowest) to class 7 (the highest).
  Since wind is an intermittent electricity generator and does not provide power on an "as needed" basis, it has to compare favorably with the costs saved on fuel from fossil generators.

 Wind Power Generator
Many utilities credit the homeowner’s account for power produced by wind turbines that is fed back to the grid and require that special safety features be installed to assure the safety of line workers during power outages.
The amount of power generated by a wind turbine depends on the capacity of the turbine (rated in kilowatts, or kW) and the wind speed.
