摘要
Abstract
A type of wind turbine clearance monitoring system is designed based on video images and millimeter wave radar.In the video clearance host,the image edge detection and other methods are used to process the images collected by the camera to obtain the tip coordinates of the wind turbine blades.The millimeter-wave radar can emit cone-shaped electromagnetic waves,which can be used to monitor the blade target points formed when the blades periodically pass through the area during the rotation of the wind turbine in real time,and output the coordinate information of the blades relative to the radar.After coordinate conversion and curve fitting,the real-time distance between the blade tip and the tower is calculated,that is,the real-time clearance of the blade.The video clearance value and millimeter wave radar clearance value are processed uniformly by a central end to output a clearance value to the wind turbine control system,so as to realize comprehensive monitoring of the wind turbine.This method can fully utilize the high resolution of video monitoring systems and the long-range detection capability of millimeter wave radar systems,effectively improving the perception accuracy and monitoring range of clearance conditions,and providing reliable guarantees for the safe operation of wind farms.The experimental results show that this method has significant effects on preventing blade tower sweeping accidents and ensuring equipment and personnel safety,and has good application prospects and promotion value.关键词
