Abstract

The invention discloses a distribution network automation communication system based on EPON technology. The distribution network automation communication system adopts a 2-layer networking mode, and multiple switches simultaneously open a fast ring network protection protocol; the central office main station and the substation are configured together At least 6 switches form a ring optical fiber Ethernet, and the substation and its subordinate power distribution terminals use EPON communication system; at least one key server is set at the main station of the central office. Compared with the existing distribution automation communication scheme, the present invention meets the requirements of distribution network automation for communication systems, has outstanding advantages in realizing low-cost, high-speed broadband and reliable optical fiber digital communication systems, and the system is scalable. The flexibility removes many of the barriers that exist in the deployment of distribution automation.

Description

technical field [0001] The invention relates to a distribution network automation communication system based on EPON technology, and belongs to the technical field of distribution network automation. Background technique [0002] Distribution network automation is to use modern electronic technology, communication technology, computer and network technology to integrate online data and offline data, user data, power grid structure and geographic graphics information of distribution network to form a complete automation system. To realize distribution network automation, communication is a key link. [0003] After rapid development in recent years, the power industry has gradually formed a huge core backbone communication network dominated by optical fiber communication. The Ethernet Passive Optical Network (EPON) technology combines the advantages of the two technologies of Ethernet and passive optical network. EPON has achieved remarkable results and has become one of the ...
