Problems solved by technology

[0002] The traditional on-line monitoring system of transmission lines adopts distributed on-line monitoring, which uses OPGW optical fiber composite overhead ground wire as a sensor to monitor the icing and temperature of transmission lines. This distributed optical fiber sensing technology mainly uses three kinds of scattering (Switzerland Scattering, Brillouin scattering and Raman scattering), these three kinds of scattering have their own advantages and disadvantages and application range, and there are still big problems in power system transmission lines

Abstract

The invention relates to a transmission line on-line monitoring system based on quasi-distributed sensor data. The transmission line on-line monitoring system comprises a plurality of transmission line towers and a monitoring center, wherein the transmission line towers are connected with the monitoring center through an OPGW optical fiber composite ground wire, a plurality of FBG icing sensors and a plurality of FBG waving sensors are arranged on the power transmission line between the transmission line towers, and are connected to an OPGW optical cable junction box through optical fibers, the OPGW optical cable junction box is fixedly arranged on a transmission line towers and is sequentially connected with an optical fiber demodulator and the monitoring center through the OPGW optical cable composite ground wire, and the optical fiber in the OPGW optical fiber composite ground wire adopts a superstructure optical fiber grating type optical fiber in a non-uniform optical fiber grating. The transmission line on-line monitoring system is beneficial to restoring of the data of warm ice coating, galloping and the like in the power transmission line to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of power transmission line monitoring, in particular to an online power transmission line monitoring system based on quasi-distributed sensor data. Background technique [0002] The traditional on-line monitoring system of transmission lines adopts distributed on-line monitoring, which uses OPGW optical fiber composite overhead ground wire as a sensor to monitor the icing and temperature of transmission lines. This distributed optical fiber sensing technology mainly uses three kinds of scattering (Switzerland Scattering, Brillouin scattering, and Raman scattering), these three kinds of scattering have their own advantages and disadvantages and application ranges, and there are still big problems in power system transmission lines. Therefore, a quasi-distributed sensing technology, that is, fiber grating sensing technology, is provided to realize online accurate monitoring of data such as icing and galloping ...
