Wind speed monitoring method, device and system for transmission line tower

Abstract

The invention discloses a wind speed monitoring speed of pole towers of a power transmission line. The wind speed monitoring speed comprises the following steps: selecting a plurality of target monitoring points in a to-be-monitored area according to a wind speed affecting factor; sending an acquisition instruction to weather monitoring devices mounted on pole towers of the target monitoring points; obtaining a target wind speed monitored value acquired by each weather monitoring device, wherein each target wind speed monitored value comprises the serial number of the corresponding weather monitoring device and target wind speed data; calculating conversion wind speed data corresponding to predetermined pole tower height according to the target wind speed monitored value by utilizing a height conversion formula; carrying out interpolating calculation on the conversion air speed data by utilizing a universal Kriging interpolating calculation method and a network analyzing method to obtain wind speed monitored values corresponding to the predetermined pole tower height of all the pole towers within the to-be-monitored area. Compared with wind speed estimation, the method can obtain wind speed monitored values of all the pole towers more accurately, so that necessary reference data is provided for line risk assessment and wind damage loss analysis.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a wind speed monitoring method, device and system for transmission line towers. Background technique [0002] According to statistics, typhoon disasters are the main reason for tripping of main network lines and downfall of distribution network towers in coastal areas, causing huge losses to the power grid and seriously affecting social production and life. [0003] When a typhoon comes, the wind speed of important line towers can only be roughly estimated, the operation risk of the line during the disaster is not clear, and there is no meteorological data reference for the analysis of the cause of each line tower failure after the disaster. Therefore, when conducting line risk assessment and wind disaster loss analysis, Without the necessary reference data, it is difficult to achieve efficient and accurate command and decision-making against typhoons. [0004] It can be...
