How are small-scale wind turbines controlled?
Small-scale wind turbines can be controlled using either electromechanical techniques such as pitch control or yaw system mechanisms, or by electrically dissipative methods. The downside of these control methods is that they are not cost-effective or efficient.
What control system does a wind turbine use?
One of the most important control systems of a wind turbine is the pitch angle control, which regulates power above the rated wind speed and protects blades during a storm . Over time, the benefits of this system have changed the wind turbine configuration from a fixed pitch to a variable pitch.
Is there a Sensorless control system for variable-speed wind turbines?
However, many commercial wind inverters adopt this method. This paper proposes an innovative sensorless control system for small (kW-range) variable-speed, fixed-pitch wind turbines with PMSG, which covers both partial-load and full-load operating modes, from cut-in to cut-out wind speeds.
How can wind turbine technology improve the efficiency of a wind turbine?
One of the most challenging issues in wind turbine technology is improving the control algorithms since it could significantly increase the efficiency. One of the most important control systems of a wind turbine is the pitch angle control, which regulates power above the rated wind speed and protects blades during a storm .
How can wind turbines be controlled without stalling?
Recently, several electrical methods have been developed to control wind turbines without stopping their operation even under high-speed wind conditions, which are known as stall control techniques and are classified into mechanical and electrical schemes.
Can small wind turbines be modeled and controlled?
Abstract: The manufacturers of small wind turbines generally provide basic parameters of their products, resulting in increased uncertainty upon evaluating the performance of small wind turbines. Therefore, the useful and accurate modeling of a small wind turbine is significant. This work discusses the modelling and control of a small wind turbine.
