Micro-meteorological phenomena, such as strong winds, rainstorms, lightning, ice, etc. in the local area, although the scope is relatively small, but its suddenness and destructive force on the grid transmission lines, but the impact should not be underestimated, and such areas are often prone to geologic hazards, which pose a serious threat to the transmission corridor, and may lead to line failures, equipment damage and even large-scale power outages. Therefore, to carry out transmission channel Meteorological disaster risk early warning. strong>Weather disaster risk early warning prediction, timely insight into micro-meteorological changes, for guarding the power arteries, to ensure the safety of the power grid is of great significance.
I. Risk analysis of meteorological disasters in transmission corridors
1. Strong winds may cause transmission lines to dance, towers to tilt or collapse, triggering short-circuit and disconnection faults.
2. Heavy rains may cause natural disasters such as floods and mudslides, which may wash away the foundation of transmission lines and cause line interruptions.
3. Direct lightning strikes or induced overvoltages may damage transmission line insulators, resulting in line tripping.
4. Under long-term cold and freezing rain conditions, transmission lines may increase in weight due to snow and ice cover, leading to conductor dancing, tower overloading and line breakage.
II. Technologies for early warning and prediction of meteorological disaster risks
Dingsin Wisdom Transmission Channel Meteorological Disaster Risk Early Warning Prediction AliasMicro-meteorological online monitoring device, with data monitoring and collection, big data analysis, machine learning algorithms and numerical simulation and other technologies, through the arrangement of high-precision meteorological monitoring sensors in the transmission tower, continuously monitoring the regional scope of the wind and the weather. By arranging high-precision meteorological monitoring sensors in transmission towers, it continuously monitors seven meteorological elements such as wind direction, wind speed, humidity, temperature, barometric pressure, precipitation, light radiation, etc., as well as the occurrence of special meteorological phenomena (e.g., thunder and lightning, icing) within a regional scope. curve at any time to master the line operating environment of the climate change rules, to prevent line outages caused by meteorological disasters.
The above is the realization of the "tower-level" weather forecast "micro-weather online monitoring" mode, weather data acquisition support "automatic, The meteorological data collection supports two different ways: automatic and controlled, and automatically collects and sends meteorological parameters at set time intervals, which has successfully monitored several micro-weather events that may affect the safe operation of the lines. As a basic Transmission line online monitoring deviceTransmission line online monitoring deviceTransmission line online monitoring device, should not be underestimated for its help in strengthening the implementation of risk response measures and enhancing the grid's ability to prevent and mitigate disasters!
