Many countries in Southeast Asia have introduced intelligent meteorological monitoring systems to facilitate the safe and efficient operation of transmission stations

With the continuous growth of electricity demand in Southeast Asia, the power departments of many countries have recently joined hands with the International Energy Agency to launch the “Smart Grid Meteorological Escort Program”, deploying new-generation meteorological monitoring stations in key transmission corridors to address the threat of extreme weather to the power system.

Technical highlights
The all-climate monitoring network: The newly established 87 meteorological stations are equipped with lidar and micro-meteorological sensors, which can monitor 16 parameters in real time, such as ice accumulation on conductors and sudden changes in wind speed, with a data refresh rate of 10 seconds per time.
AI Early Warning Platform: The system analyzes 20 years of historical meteorological data through machine learning and can predict the impact of typhoons, thunderstorms and other disastrous weather on specific transmission towers 72 hours in advance.

Adaptive regulation system: In the pilot project in Vietnam, the meteorological station was linked with the flexible DC transmission system. When encountering strong winds, it could automatically adjust the transmission power, increasing the line utilization rate by 12%.
Progress of regional cooperation
The cross-border power transmission channel between Laos and Thailand has completed the networking and debugging of 21 meteorological stations
The National Grid Corporation of the Philippines plans to complete the renovation of 43 stations in typhoon-prone areas within this year
Indonesia has connected meteorological data to the newly-built “Volcanic Ash Warning Power Dispatch Center”.

Expert Opinion
“The climate in Southeast Asia is becoming more uncertain,” said Dr. Lim, the technical director of the ASEAN Energy Centre. “These micro weather stations, which cost only $25,000 per square kilometer, can reduce the cost of power transmission fault repair by 40%.”

It is learned that the project has received a special loan of 270 million US dollars from the Asian Development Bank and will cover the major cross-border interconnection power grids in ASEAN over the next three years. China Southern Power Grid, as a technical partner, shared its patented technology in mountainous meteorological monitoring in Yunnan.
