摘　　要：随着科技的发展以及电子设备越来越普及,环境中的电磁能量越来越密集。文章针对环境电磁能量对电网HPLC+HRF(高速载波+高速无线)双模通信单元的干扰问题进行研究。分析了因强干扰导致通信单元损坏的用电台区的电磁环境,抓取了导致通信单元损坏的噪声波形,并利用带阻滤波器实现了对干扰信号的抑制。同时为了弥补带阻滤波器的插入损耗,对无线信号的发射通路和接收通路均进行了补偿,保证了无线通信的性能。最终通过现场试验,杜绝了通信单元损坏的问题。With the development of science and technology and the increasing popularity of electronic devices,electromagnetic energy in the environment is becoming more and more dense.In this paper,the interference problem of environmental electromagnetic energy on HPLC+HRF(high-speed carrier+high-speed wireless)dual-mode communication unit of power grid is studied.The electromagnetic environment of the station area where the communication unit is damaged due to strong interference is analyzed,and the noise waveform caused by the communication unit is captured,and the interference signal is suppressed by band-stop filter.At the same time,in order to compensate the insertion loss of band-stop filter,the transmitting and receiving channels of wireless signal are compensated,which ensures the performance of wireless communication.Finally,through the field test,the problem of communication unit damage is eliminated.
