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.
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.
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.
Nevertheless, both the rotor of a variable speed wind turbine (VSWT) and a generator directly connected to the grid possess KE that can be used to enhance the grid frequency [15, 16]. System frequency and different operating ranges [13, 14].
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
