Clearance monitoring calculates the distance between the blade and the tower
1,Product introduction
The clearance radar transmits the ranging data or the calculated clearance value data to the wind turbine master control, and the wind turbine master control takes corresponding actions according to the data, such as adjusting the pitch angle when the clearance value is low, and emergency shutdown when the clearance value is too low.
