摘要
为提高对电磁信号局放源定位的精度,提出基于传播路径特性分析的电磁信号局放源定位方法.首先,构建电磁信号局放源分布式信息融合模型,利用电磁信号输出时间序列重组方法分解信号特征,然后采用匹配滤波检测方法对电磁信号局放源输出的噪声进行抑制,从而提取电磁信号局放源特征量,再通过电磁信号传播路径信息重组方法,对电磁信号局放源进行空间分布式重构,并完成节点优化部署,从而实现电磁信号传播路径的均衡处理,完成电磁信号局放源的定位优化.仿真结果表明,该方法对电磁信号局放源定位的准确度较高,信道均衡性较好,输出电磁信号的信噪比较高.
To improve the localization accuracy of electromagnetic signals,a localization method based on propagation path analysis is proposed.The discharge source electromagnetic signal distributed information fusion model is builded.The signal characteristic is decomposed by using the restructuring method of electromagnetic signal output time series.The matched filtering method is adopted to discharge and suppress source electromagnetic signal output noise so that the discharge source electromagnetic signal characteristic information is extracted.Then the discharge source electromagnetic signal space reconstruction is distributed and the node deployment optimization is completed through the electromagnetic signal propagation path information restructuring method,distributed to and complete,so as to realize the equilibrium of the electromagnetic signal propagation path processing and complete electromagnetic signal source of partial discharge location optimization.The simulation results show that the method has higher accuracy in locating the local emFS,better channel equalization and higher SNR of the output EMFs.
