How are wind farms controlled?
The focus of is coordinated control of wind farms over three control levels: central control, wind farm control, and individual turbine control. Under-load tap changing transformers and convectional mechanical switched capacitors are used to implement the control strategies, which can be implemented on both fixed- and variable-speed turbines.
Do wind turbines have operational control strategies?
This review paper presents a detailed review of the various operational control strategies of WTs, the stall control of WTs and the role of power electronics in wind system which have not been documented in previous reviews of WT control. This research aims to serve as a detailed reference for future studies on the control of wind turbine systems.
How do utility-scale wind turbines work?
Utility-scale wind turbines have several levels of con-trol, which can be called ‘supervisory control,’ ‘operational control,’ and ‘subsystem control.’ The top-level supervisory control determines when the turbine starts and stops in response to changes in the wind speed, and also monitors the health of the turbine.

What is a pitch controlled wind turbine?
Pitch controlled WTs have an active control system which varies the pitch angle of the turbine blades to decrease torque and rotational speed in WTs. This type of control is usually employed in high wind speeds only where high rotational speeds and aerodynamic torques can damage the equipment.
