Design of wind load response on-line monitoringsystem based on ZigBee technology for electric transmission line

输电线路风荷载是影响安全运行的重要因素,而在线监测系统是应对风灾害较好的方法之一。文中从风偏机理、风偏闪络的发生条件、风偏角典型计算方法等方面分析了输电线路风偏故障。提出一种基于ZigBee技术的输电线路风荷载在线监测系统,并介绍了系统的组成和相应功能。通过该系统采集的现场数据与风偏角典型计算方法得到的结果有较好的吻合。目前,该系统直接应用于贵州电网公司六盘水输电线路试验基地,可以有效地指导输电线路风荷载的运行维护管理。

The wind load on electric transmission line is an important factor that seriously affects safe operation.The on-line monitoring system is one of the better methods to deal with wind disaster.The wind yaw faults of transmission lines are analyzed in the aspects of wind deflection mechanism,occurrence conditions of wind deflector flashover,and typical calculation methods of wind deflection angle.An on-line wind load monitoring system based on ZigBee technology is presented.The composition and corresponding functions of the system are introduced.The field data collected by the system can tally well with the data got by the typical calculation method of wind deflection angle.At present,this system has been directly applied to transmission line maintenance management dealing with wind loads.
