基于北斗卫星差分定位技术的输电线路弧垂监测

摘要

输电线路运行区域广泛，其安全稳定运行受到包括气象、地形地貌、输电线路走廊环境变化、导线负荷变化等多类因素的影响。当环境温度升高或导线负荷增加时，都会引起导线温度升高，弧垂增大，影响导线对地距离。本论文针对目前架空输电线路弧垂监测精度不高的问题，利用北斗卫星差分定位技术，研发基于北斗卫星差分定位技术的输电线路弧垂监测装置，很好的解决了输电线路弧垂监测的难题。%The Transmission line covers a wide area. Issues such as weather, topography, transmission line corridors, environ-mental change, and current change, etc. may effect the safe and stable operation of the wire. When the environment tempera-ture or wire current increases, the temperature rise will cause the line sag to increase, which leads to ground distance. This pa-per focuses on how to solve the problem, as the overhead transmission line sag cannot be monitored correctly. The Beidou mon-itoring system can better solve the problem of the transmission line sag.
