Abstract
With the development of smart distribution networks, more and more automation equipment and power terminal equipment are connected to the network. At present, power line communication (PLC) and 5G communication technologies have certain applications in the distribution communication network, but they also have some problems. Since the power line is not a dedicated communication line, the line has strong noise interference and severe attenuation of high-frequency signals. It is difficult to meet the real-time and reliability requirements of intelligent power distribution network for information transmission by simply using PLC for communication. In terms of wireless communication, the purely use of 5G public network communication is faced with problems such as safety problems in transmitting information on the distribution network, signal blind spots, and service costs. Therefore, according to the business needs of the smart distribution network, this paper studies the smart distribution network communication system integrating power line carrier and 5G communication, so as to effectively improve the overall performance of the communication and provide low-cost, reliable and flexible access for the smart distribution network. means of information transmission.
