Abstract

The invention discloses a power distribution network automatic communication system based on the EPON technology, and the system employs a two-layer networking mode, and enables a plurality of switches to start a quick looped network protection protocol at the same time. The local side master station and the transformer substation are provided with at least six switches in total to form an annularoptical fiber Ethernet, and the transformer substation and the subordinate power distribution terminals adopt an EPON communication system. At least one key server is arranged at the local side master station. Compared with an existing power distribution automation communication scheme, the system meets the requirements of power distribution network automation for a communication system, has outstanding advantages in the aspect of achieving a low-cost, high-speed, broadband and reliable optical fiber digital communication system, and eliminates many obstacles existing in power distribution automation deployment through the expandability of the system.

Description

technical field [0001] The invention relates to a distribution network automation communication system based on EPON technology, which belongs to the technical field of distribution network automation. Background technique [0002] Distribution network automation is the use of modern electronic technology, communication technology, computer and network technology to integrate the online and offline data, user data, power grid structure and geographic graphic information of the 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 based on optical fiber communication. Ethernet Passive Optical Network (EPON) technology combines the advantages of Ethernet and passive optical network technologies. EPON has achieved remarkable results and has become one of the main commun...
