Overview of Communication Network Switches Technology Development in Smart Substations

摘要

As an important component of the smart grid, smart substations adopt the optical fiber as the main feature to replace the traditional cable communication network. Therefore, it is very important to research the key equipment switch technology of the smart substation network. This article first compares and summarizes the technical specifications and Changes in standards of switches in smart substations and the technical characteristics of each stage. Secondly, the latest performance requirements of the switch are analyzed. Then from the perspective of function realization, we discussed the key technologies that support the development of switches. Finally, the key research points and research prospects of smart substation network switch technology are summarized and prospected.
