Chengxue Zhang · Dianli zidonghua shebei · 2012
An online monitoring method of transmission conductor wave and wind gallop is proposed based on DGPS(Differential Global Positioning System),which obtains the spatial location information of transmission conductors in real time by DGPS technology and sends it to the server on ground by wireless transmission technology.The monitoring program of server converts the spatial location information into the spatial position information in Cartesian coordinates system,the error of which is processed by the artificial neural network.The reproduction program of server reproduces the tracks of conductor wave and wind gallop according to the real-time spatial location information.Results of site test for a 500 kV transmission line show the wave and wind gallop of transmission conductor are monitored in real time with the accuracy of centimeter class.
