高压输电线路舞动是影响我国输电线路安全的重要原因，传统基于无线传感器的舞动监测系统需要较多的传感器才能获得较高的波形重构精度，不仅成本较高还会增加输电线路负荷。针对该问题，提出一种基于高斯模型联合CLEAN算法的架空输电线路舞动波形重构方法。对输电线路舞动的机理进行数学分析，并建立传感器缺失观测下输电线路舞动波形重构问题，利用高斯模型对上述问题进行分析，实现传感器缺失监测条件下的数据恢复，利用CLEAN算法对恢复后的数据进行提取，从而实现架空线路舞动波动精确重构。仿真结果表明，在传感器数量减少50%条件下，波形重构误差仍可控制在15%以下。

The dancing of high voltage transmission lines is an important reason affecting the security of transmission lines in our country. Traditional dancing monitoring system based on wireless sensors requires more sensors to obtain a higher waveform reconstruction accuracy, which not only costs higher and also increases the loads of the transmission lines. In order to solve this problem, a new dancing waveform reconstruction method for overhead transmission lines based on Gaussian model combined with CLEAN algorithm is proposed. The mechanism of transmission line dancing is analyzed mathematically and the reconstruction problem of transmission line dancing waveform under sensor missing observation is established. The Gaussian model is used to analyze the above problems and realize the data recovery under sensor missing monitoring condition. The CLEAN algorithm is used to extract the recovered data, so as to realize the accurate reconstruction of overhead line dancing fluctuation. The simulation results show that the waveform reconstruction error can be controlled below 15% when the number of sensors is reduced by 50%.
