基于差分GPS的输电线路舞动和风偏在线监测方法

提出了一种基于差分全球定位系统(DGPS)的输电线路舞动和风偏在线监测方法。该方法基于DGPS定位原理,通过DGPS技术实时获取输电线路的空间位置信息,得到的导线空间位置信息经无线传输技术传输到地面服务器中,服务器中的在线监测程序提取出定位信息中导线的经度、维度和高度三维空间信息转换成三维笛卡尔坐标系中的坐标值,利用人工神经网络技术对定位数据进行误差处理,输电线路舞动和风偏轨迹再现程序根据实时的空间位置信息再现导线的舞动和风偏轨迹。研制的在线监测系统对一条500 kV输电线路的舞动和风偏进行了现场测试。结果表明,所提方法可对输电线路舞动和风偏进行厘米级的实时在线监测。

Online monitoring of transmission conductor wave and wind gallop based on differential GPS

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.
