变电站通信设备电磁环境参数测量分析

Measurement and analysis of electromagnetic environment parameters of substation communication equipment based on moment method

利用传统电磁参数测量方法不能同时完成信号流分选、脉冲流分离交错处理。为解决上述问题,提出基于矩量法的变电站通信设备电磁环境参数测量分析方法。利用电场基函数处理介质体电磁阻抗元素的奇异性,在根据电磁环境属性完成散射磁通量的离散分类,实现通信介质体的电磁散射结果确定。在此基础上,利用电磁环境特征完成信号脉冲周期分选、精测带宽确定,实现基于矩量法的变电站通信设备电磁环境参数测量分析。设计对比实验结果显示,与传统方法相比,应用新型参数测量分析方法后,信号流、脉冲流截获概率均得到大幅提升,完成信号流分选、脉冲流分离交错的同时处理。

By using traditional electromagnetic parameter measurement method,signal flow sorting and pulse flow separation interleaving can not be completed simultaneously.To solve the above problems,a method of electromagnetic environmental parameters measurement and analysis for substation communication equipment based on moment method is proposed.The singularity of the electromagnetic impedance element is treated by the base function of the electric field.The scattering of the scattering flux is classified according to the properties of the electromagnetic environment,and the electromagnetic scattering results of the communication medium are determined.On this basis,the electromagnetic environment characteristics are used to complete the signal pulse cycle sorting and the precision measurement bandwidth to realize the measurement and analysis of the electromagnetic environment parameters of the substation communication equipment based on the moment method.The experimental results show that,compared with the traditional method,with the new method of parameter measurement,the signal flow and the interception probability of the pulse flow are greatly improved,and the signal flow separation and pulse flow separation are simultaneously processed.
