Why do wind turbines use asynchronous generators?
Asynchronous generators, or induction generators, are extensively utilized in wind turbines due to their robustness, cost-effectiveness, and capability to generate reactive power to support the grid. Though these generators can initially appear cheaper, the long-term costs associated with rare earth magnets can be high.
What is a direct connected asynchronous generator?
Direct-Connected Induction (Asynchronous) Generators, also known as Type I generators, are widely used in wind turbines due to their robustness, cost-efficiency, and reactive power generation capability.
How much power does an asynchronous generator have?
For an asynchronous generator with a power of 1.1 kW, a synchronous machine with a power of 1.2 kW is adopted, which allows to stabilize the voltage on the stator of the asynchronous generator, when the wind speed changes from 0 to 25 m·s-1.
How much power does an asynchronous wind turbine produce?
As the asynchronous machine operates in generator mode, its speed is slightly above the synchronous speed (1.011 pu). According to turbine characteristics, for a 10 m/s wind speed, the turbine output power is 0.75 pu (206 kW). Because of the asynchronous machine losses, the wind turbine produces 200 kW.
How synchronous generator is used for irregular wind energy conversion?
Wind energy is the form of sun energy. Flow of wind is not uniform all time. For conversion of wind energy into electrical energy synchronous generator were used. Synchronous generator used for the constant speed of power generation. So using synchronous generator for irregular wind energy conversion in electrical energy is not efficient.
Is asynchronous generator better than fixed speed generator?
So using synchronous generator for irregular wind energy conversion in electrical energy is not efficient. Due to such disadvantages of fixed speed generator, recent days variable speed generator using called doubly fed induction generators. This asynchronous generator has many advantages over fixed speed generator system.
