Experimental Study on Yaw Control System of Small Wind Turbine

In order to improve the efficiency of wind turbine, a small wind turbine yaw control system based on PLC was proposed. The experiment platform was built with PLC as the controller, wind speed and direction sensor as the detection device, and stepper motor as the yaw drive device. Wind speed and direction data acquisition based on modbus communication, yaw motor control based on PLS instruction programming and upper computer monitoring based on MCGS configuration software were mainly introduced. The system test and experiment verified that the data acquisition system could display the field wind speed and direction data in real time, and the yaw motor could automatically face the wind according to the change of wind direction, which met the control requirements and achieved good control effect, with the advantages of low cost and good stability. The application of the system provides a guarantee for improving the efficiency of wind energy and provides a reference for the control of yaw motor of small wind turbine
