AI Technical Summary
Technical Problem
During the yaw process of wind turbines, factors such as blade disturbance can cause errors in the anemometer measurement, affecting the accuracy of wind alignment and consequently impacting wind energy acquisition.
Method used
The parameters affecting yaw correction, including axial wind speed and yaw angle error, are measured using lidar. The effectiveness of these parameters is then determined by an industrial computer, which calculates the yaw correction error compensation and sends the results to the controller for yaw wind control.
Benefits of technology
It improves the wind turbine's accuracy in locating wind, increases wind energy harvesting, extends the life of the yaw system brake pads, and reduces power consumption.
