Document Type and Number:
WIPO Patent Application WO/2023/238348
Kind Code:
A1
Abstract:
A power line operation assistance device that assists with operation of a power line constructed on a power transmission tower together with an optical fiber composite overhead line, the power line operation assistance device comprising: a weather data acquisition unit that acquires prescribed types of weather data including air temperature, wind conditions, and insolation at a prescribed position on the power line; a current value acquisition unit that acquires a current value flowing through the prescribed position on the power line; and a first temperature calculation unit that inputs the weather data and the current value at the prescribed position to a first relational expression representing the relationship between the current value, temperature, wind conditions, and insolation of the power line and the temperature of the power line, thereby calculating the temperature of the power line at the prescribed position. The weather data acquisition unit acquires wind conditions calculated on the basis of a result of measuring a vibration state of the optical fiber composite overhead line, which is measured using a distributed multipoint vibration measurement method, as the wind conditions at the prescribed position.
