Abstract:
Wind energy, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions during operation. Wind electrical generation systems are the most cost competitive of all the environmentally clean and safe renewable energy sources in the world.
Wind system uses squirrel cage induction generators and fed power to utility grids or autonomous loads.
The system requires external reactive power source to support grid voltage and it can keep the output power at the nominal level by pitch control.
