The evolution of communication technology and electric energy metering management of remote automatic meter reading system in power grid

Abstract: This paper mainly introduces the remote automatic meter reading system technology of the State Grid in the early 90s of the 20th century, and with the introduction of electronic meters and smart meters, the local and remote communication technology has been rapidly updated, which has promoted the development of remote automatic meter reading system technology. From 2010 to 2018, the State Grid carried out the large-scale construction of the provincial power grid electricity information collection system, and invested a lot of money in the construction of collection equipment and user projects. By the end of 2018, the number of smart meters operated by the State Grid reached 458 million, and the user coverage rate of the electricity information collection system reached 99.87%. In the area of communication technology, the text refers to the development of local and remote communication methods. The local communication mode has undergone the evolution from narrowband powerline carrier communication technology to broadband powerline carrier communication technology, while the long-distance communication mode has successively adopted GPRS and 4G public network wireless communication. This paper also introduces the origin, development and gradual fading out of the market of narrowband CLC technology, as well as the rise and development of broadband CLC technology.
