The invention discloses an OPGW (optical fiber composite overhead ground wire) terminal monitoring system which comprises a terminal, a collector and a master station. The terminal is used for collecting OPGW grounding currents and acquiring corresponding grounding current alarm information, lightning overvoltage frequency information and operating overvoltage information according to the grounding currents; the collector is matched with the terminal during use and is used for receiving the OPGW grounding currents measured by the terminal and uploading the OPGW grounding currents, the grounding current alarm information, the lightning overvoltage frequency information and the operating overvoltage information to the master station; the master station is used for receiving the data of the collector and monitoring the OPGW grounding currents, the grounding current alarm information, the lightning overvoltage frequency information and the operating overvoltage information. The OPGW terminal monitoring system has the advantages that key technical parameters such as the OPGW grounding currents and lightning overvoltage frequency can be accurately measured by the system in real time, OPGW operation conditions can be comprehensively analyzed and assessed, and accordingly effective data can be provided for an electric power system and a powerful basis can be provided for condition-based maintenance.
Description
technical field [0001] The invention relates to the technical field of power monitoring, in particular to an OPGW terminal monitoring system. Background technique [0002] OPGW optical fiber communication is an important part of the power communication backbone network, which carries the production information of the power grid. During the current period of rapid development of smart grids in China, a large number of OPGWs are used in power communication for optical fiber backbone networks. In order to improve the reliability of the safe operation of smart grids, the safe and full operation of OPGW optical fiber communication networks is particularly important. Based on the principle of "safety first and prevention first" in power grid production management, the OPGW substation terminal system is included in the operation and inspection management of substation equipment status. [0003] So far, no online monitoring method for OPGW detection has been found. The previous met...
