Abstract

The invention belongs to the technical field of electric power monitoring, and particularly relates to a monitoring method and a monitoring system for icing of an optical fiber composite overhead ground wire. The monitoring method for icing of the optical fiber composite overhead ground wire comprises the steps that S1, a ground wire composite optical cable is erected on ground wire hanging pointsof at least two adjacent electric power towers, and at least one monitoring point is arranged in the length direction of the optical cable; S2, each monitoring point of the optical fiber sensor uploads the obtained data to a cloud processor at a specified time interval, and the cloud processor compares the data obtained at the current time with the data obtained at the previous time; and S3, if the data obtained at the current time of the cloud processor is greater than the data obtained at the previous time, it is judged that the icing thickness is increased, and the cloud processor performsdifference calculation on the data obtained at the current time and the data obtained at the previous time. The invention provides a monitoring method for icing of the optical fiber composite overhead ground wire, which is simple to operate and does not need complicated calculation of data.

Description

technical field [0001] The invention belongs to the technical field of electric power monitoring, and in particular relates to a method for monitoring icing of an optical fiber composite overhead ground wire and a monitoring system thereof. Background technique [0002] Optical fiber composite overhead ground wire (OPGW) is a very important cable in my country's power transmission lines. OPGW acts as an optical fiber carrier for the power system communication network and also acts as a lightning conductor. [0003] In winter, power transmission lines in some areas in southern my country are prone to ice. If the icing of the OPGW is too serious, the OPGW cable may be broken and the tower may be toppled, resulting in serious power transmission accidents. [0004] Therefore, to monitor his icing situation, the monitoring means of icing is currently on the transmission line, and there are weighing devices for monitoring the weight of the line on some power poles, depending on t...
