How does a constant speed wind turbine work?A constant speed wind turbine operates at the maximum power point according to the wind conditions to control the active and reactive power of the machine. This is achieved through power electronics for machine control. The turbine may include a synchronous or induction generator.
How do wind turbines control rotary speed and grid frequency?In constant speed wind turbines, the control system decouples the rotary speed and grid frequency. This means that the wind turbines cannot provide corresponding active power when grid frequency varies, reducing the inertia of the whole power grid.
How does a variable speed wind turbine operate?In a variable speed wind turbine, the rotor speed increases with wind speed up to a certain limit. This allows for quieter operation at low wind speeds compared to a constant speed wind turbine.
How do wind turbines control primary frequency?The primary frequency control by wind turbines can be integrated into the rotor-side active power control loop and demonstrate behavior similar to conventional synchronous generators. The wind turbine must operate in curtailed mode to provide reserve for primary response when frequency drops.
How is a wind turbine controlled?The conventional control of a wind turbine involves regulating the power yield and rotor speed. In above-rated wind conditions, the generator power should be as close as possible to the rated value. In below-rated wind speeds, the rotor speed should 'track' the wind speed to gain maximum energy yield.
What algorithm is used for constant speed wind turbines?For constant speed wind turbines, the FFT algorithm is directly applied to the measured acceleration time signals a ( t ) to analyse periodic nacelle oscillations. To analyse nacelle oscillations of variable speed wind turbines, a modified algorithm has to be used which is called order analys
