架空输电线路的弧垂高度是线路安全运行的关键指标。为了实现有效的输电线路弧垂监测，基于悬链线方程、力学模型和几何学模型，建立导线在三维空间内的监测模型。使用 Matlab 工具实现计算模型，实时监测输电线路的弧垂变化，根据导线倾角计算出的弧垂高度判断导线的运行状态，由监控人员进行统一管理，指挥巡检人员进行线路检修和导线防舞处理。实验结果表明，建立的舞动模型能够快速准确地计算出弧垂高度和偏移量，精确地反映了弧垂的变化趋势，极大地提高了计算效率，可以保证输电线路的安全运行。

The sag height of overhead transmission lines is an essential indicator for safe operation of the line.In order to achieve effective transmission line sag monitoring,the paper establishes a monitoring model of wires in three-dimensional space based on catenary equation, mechanical model and geometry model.Besides it implements a computational model by Matlab tools.It real-timely monitors the changes of transmission lines sag,judges the conductor operational status by sag height calculated from wire inclination,managed unitarily by monitoring personnel to assign inspection personnel with line maintenance work and wire anti-vibration handling.Experimental results show that the vibration model can quickly and accurately calculate the sag height and offset,and can precisely reflect the sagging trend.Therefore it greatly improves the computational efficiency and can ensure the safe operation of the transmission lines.
