摘要:
针对变电站无线4G通讯链路易受强电磁脉冲干扰问题,分析了两种常用的变电站通信常用的传播模型,研究了无线传输的调制解调技术,建立了几种典型强电磁脉冲如高压正弦电磁脉冲、EFT电磁脉冲群、浪涌脉冲的解析函数模型. 搭建了无线通讯链路仿真平台,以BPSK调制解调方式为例,分析了各典型强电磁脉冲在5%误码率情况下对通讯链路的影响,仿真结果表明,浪涌脉冲对无线传输的影响程度最大,从而为强电磁脉冲抑制方法设计提供了理论依据.
Abstract:
Focusing on the problem that the substation 4G wireless communication link is easily interfered by strong electromagnetic pulse,this paper introduces the two common transmission models commonly used in substation communication link,and analyzes the modulation and demodulation technology of wireless transmission. Meanwhile,the models of several typical strong electromagnetic pulse,such as high voltage sine electromagnetic pulse,EFT electromagnetic pulse group,and the surge pulse,have been established in this paper. In this paper,a simulation platform of wireless communication link is also established,and the influence of typical strong electromagnetic pulse on communication link under the case of 5%-bit error rate is analyzed by taking BPSK modulation and demodulation mode as an example. The simulation shows that the influence degree of surge pulse is the severest,which provides a theoretical basis for future strong electromagnetic pulse suppression methods.
