Due to the uncertainty of the environment in which the transmission lines are located in the power grid, whether the safe operation of the line has become an important indicator of the reliability of the power grid.
In the past, the line inspection mainly relied on the periodic inspection of operation and maintenance personnel, although hidden dangers could be found, but due to its own limitations, it was not possible to grasp the implementation of the line in time, therefore, the application of the line monitoring system was born, which was born through wireless (GPS 4G) communication transmission mode, the environmental temperature and humidity of the transmission line, wind speed and direction, light, rainfall, icing, dancing, vibration, sag, insulator pollution flashover, wire fittings temperature, tower inclination, Real-time monitoring of the surrounding construction conditions, providing early warning of abnormal conditions of the line, and effectively improving the safe operation of the transmission line through real-time monitoring of the line and tower.
Monitoring principle: Wuhan Wind River Intelligent's transmission line monitoring system consists of two parts, the front-end of data acquisition (solar panels, communication modules, acquisition systems, anti-jamming systems, etc.) and the back-end system. The front-end acquisition unit adopts the point solar panel + battery power supply mode, which can ensure the all-weather operation of the equipment, and conduct real-time data collection and analysis on the micro-meteorology, tower status and wire status of the surrounding environment through pre-set programs, and then transmit it to the background through wireless communication, and the background analyzes the collected data, when the data exceeds the set value, the system will give an early warning through the web and text messages, etc., to remind the operation and maintenance personnel to take preventive measures in time to reduce the occurrence of line accidents.
