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.
