摘　　要：电力系统中高压输电线路既是能量传递的“动脉”,又担负着传递信息的重任。在智能电网飞速发展的今天,要求电力通信系统既要高效可靠地传递控制指令,保护信号和计量数据,又要保证这些信息不受复杂电磁环境的干扰,维持通信准确实时。然而,由于高压输电线路及其周围环境的独特性,电力通信系统不得不面对多种可能的干扰因素,包括电磁干扰、雷电干扰,以及其他电力线路和通信设备产生的信号干扰等,这就直接关系到通信质量与可靠性,进而引起人们对于抗干扰技术的迫切要求。所以研究和应用行之有效的抗干扰技术来保障电力通信系统平稳运行就成了电力行业急需解决的一个重点问题。基于此,本篇文章将对高压输电线路电力通信系统抗干扰技术进行多方面的论述,希望可以为相关的研究提供一定的参考建议。In the power system,the high-voltage transmission line is not only the"artery"of energy transmission,but also the important task of transmitting information.Today,with the rapid development of smart grid,power communication systems are required to transmit control instructions efficiently and reliably,protect signals and metering data,and ensure that these information are not interfered with by complex electromagnetic environment to maintain accurate and real-time communication.However,due to the uniqueness of high-voltage transmission lines and their surrounding environment,power communication systems have to face a variety of possible interference factors,including electromagnetic interference,lightning interference,and signal interference generated by other power lines and communication equipment,which is directly related to the quality and reliability of communication,and then cause people's urgent requirements for anti-interference technology.Therefore,the research and application of effective anti-interference technology to ensure the smooth operation of power communication system has become a key issue urgently needed to be solved in the power industry.Based on this,this article will discuss the anti-interference technology of high-voltage transmission line power communication system in many aspects,hoping to provide some reference suggestions for related research.
