[0002] The intelligent fan control assembly as the key part of guaranteeing the high efficiency and stable operation of the fan plays a vital role in the wind power generation system. The control assembly usually contains various key components to realize the accurate control of the fan in all directions:

[0003] 1. Controller: as the core of the control assembly, it is responsible for collecting and processing data from various sensors, making calculations and decisions according to the preset control strategy, and then issuing instructions to other execution components to achieve accurate control of the fan speed, wind direction, power and other key parameters.

[0004] 2. Sensor: including wind speed sensor, used to measure the wind speed around the fan in real time and provide wind speed information for the controller to adjust the fan operating state reasonably according to the wind speed change.

[0005] 3. Actuator: the pitch mechanism can adjust the blade pitch angle to adjust the wind energy capture efficiency and output power of the fan.

[0006] 4. Power module: provides stable power supply for each component in the control assembly, usually composed of rectifiers, filters, voltage stabilizers, etc. It converts the external input AC power into DC power suitable for each component and ensures the stability and reliability of the power supply.

[0007] Currently, in order to realize the efficient operation of the intelligent fan control assembly, various technical means and equipment are adopted in the industry. Some manufacturers choose high-performance programmable logic controllers (PLC) as controllers to realize complex logic control; some manufacturers use advanced digital signal processors (DSP) to realize high-precision control with their powerful digital signal processing capabilities. In terms of sensors, some manufacturers use new laser wind speed sensors for higher measurement accuracy, or use MEMS wind direction sensors for small size and fast response. In terms of actuators, some manufacturers use electric pitch and yaw systems for high control accuracy and fast response speed; some manufacturers choose hydraulic actuator for large output force and stable operation.
