Abstract

The invention provides an arrangement method and a monitoring device of an electric power optical fiber power distribution communication network. The method comprises the following steps: simplifying the network topology from an optical line terminal to an optical network terminal as a communication node and an optical fiber line, and obtaining a network structure diagram based on Brillouin scattering center frequency and distance and marked after the construction of the electric power optical fiber power distribution communication network is completed; obtaining a network structure diagram based on Brillouin scattering center frequency and distance of the electric power optical fiber power distribution communication network; and finally, comparing the network structure diagram based on Brillouin scattering center frequency and distance of the electric power optical fiber power distribution communication network with the network structure diagram based on Brillouin scattering center frequency and distance and marked after the construction of the electric power optical fiber power distribution communication network is completed to find the frequency spectrum that may be lost and determine the geographic information of an optical fiber breakpoint. According to the arrangement method, the features of each optical fiber in the electric power optical fiber power distribution communication network are distinguished, thereby avoiding the problem that the optical fiber paths in the network cannot be separated due to the superposition of Rayleigh scattering signals in the traditional monitoring scheme.

Description

technical field [0001] The invention relates to a monitoring technology, in particular to an arrangement method and a monitoring device for an electric optical fiber power distribution communication network. Background technique [0002] In recent years, the optical fiber power distribution communication network has been greatly developed and has become an important part of the power transmission and transformation link of the smart grid. With the continuous improvement of power supply reliability requirements, power grid operation is facing great challenges, which objectively require real-time monitoring and remote control of the distribution network operation status. The construction and operation of the distribution automation system can effectively reduce the fault handling time, further enhance the lean management ability of production and operation, and improve the power supply service level. The realization of power distribution automation is based on the informatiza...
