Power transmission line wind speed measurement method, system and device and storage medium

Abstract

The invention provides a power transmission line wind speed measurement method, system and device and a storage medium. The method comprises the following steps: measuring a strong-wind-load-free actually-measured tension value of a suspension tower insulator string through a tension sensor in advance; according to the actually measured tensile force value without the strong wind load, obtaining the vertical span of the overhanging tower; measuring a strong wind load actual measurement tension value of the suspension tower insulator string through the tension sensor; obtaining the wind load per unit length of the power transmission line according to the vertical span of the overhanging tower and the actually measured tensile force value of the strong wind load; and obtaining a wind speed value according to the wind load per unit length of the power transmission line. The real wind load borne by the power transmission line can be effectively measured only by installing the tension sensor at the hanging point of the ground wire of the suspension tower to measure the tension of the insulator chain, and then the real and accurate wind speed is obtained, so that the measurement method is simple, scientific, reliable and wide in application range; and the troubleshooting efficiency of the power transmission line safety is improved, and the monitoring, operation and maintenance cost of the power transmission line safety is saved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a wind speed measurement method, system, device and storage medium of a power transmission line. Background technique [0002] At present, electricity is an indispensable energy source in people's life, and its role in different fields such as lighting, power tools, power transportation, heating and cooling, scientific research, network media, communication and social interaction, military aerospace, and agricultural development can be fully utilized. It is inseparable from the power network, let alone the protection of transmission lines. However, the safety of outdoor transmission lines is easily affected by external forces, such as sudden strong winds, typhoons, etc., which will generate wind loads on the transmission lines, and when the wind load exceeds the design value, accidents such as dropped lines and disconnected lines will occur, seriously Sometimes it will c...

AI Technical Summary

Problems solved by technology

However, the method of measuring the wind speed at the position of the transmission line using wind speed sensor measurement or weather forecast data is very susceptible to the influence of factors such as topographical distortion of the wind field, irregular observation methods, or limitations in observation conditions, making it difficult to truly and accurately measure the wind speed of the transmission line. Measuring the wind speed of the transmission line cannot accurately reflect the actual wind load on the transmission line, which will affect the accuracy and effectiveness of the risk assessment of the transmission line, the decision-making against wind disasters, and the analysis of wind disaster losses
