Description

Technical field [0001] The invention belongs to the technical field of power carrier, and specifically relates to a power carrier communication system. Background technique [0002] Smart grid is a power transmission and distribution network that uses sound dual-channel communications, advanced sensors, and distributed computing. Its purpose is to improve the efficiency of power transmission and use, and improve the reliability and security of the power grid. The establishment of a high-speed, two-way, real-time, and integrated communication system is the basis for the realization of a smart grid. At present, the main transmission methods of the distribution communication network are: optical fiber, public wireless network, self-built dedicated wireless network, power line carrier communication, power line power frequency communication and other methods. Power line power frequency communication realizes data transmission by superimposing tiny distortion signals on voltage and cu...
