In today’s society, a stable electricity supply is the cornerstone of economic development and people’s lives. The weather factor, as an important variable affecting the safe operation of power grid, is receiving unprecedented attention. Recently, more and more power grid enterprises have begun to introduce advanced weather station technology to escort the stable operation and efficient management of power grids.
Weather stations become “smart guards” of power grid
Traditional power grids are often vulnerable to extreme weather. Severe weather, such as strong winds, heavy rain and snow, can cause transmission line failures, substation equipment damage, and then lead to a large area of power outages. Last year, a sudden strong typhoon hit the Philippine island of Luzon, causing a number of transmission lines in the region to blow down, hundreds of thousands of residents into darkness, power repair work took several days to complete, to the local economy and residents’ lives had a huge impact.
Today, with the spread of grid-based weather stations, the situation has changed. These weather stations are equipped with high-precision meteorological monitoring equipment, which can monitor wind speed, wind direction, rainfall, temperature, humidity and other meteorological parameters in real time, and analyze and forecast meteorological data through intelligent algorithms. Once severe weather that may affect the security of the power grid is detected, the system will immediately issue an early warning, providing sufficient time for power grid operation and maintenance personnel to take countermeasures, such as strengthening transmission lines in advance and adjusting the operation status of substation equipment.
Practical cases show remarkable results
In Daishan County, Zhoushan City, Zhejiang Province, China, power grid companies fully deployed a weather station system early last year. During a heavy rainfall last summer, weather stations detected that rainfall would exceed the warning value several hours in advance and quickly sent the warning information to the power grid dispatch center. According to the early warning information, the dispatching personnel timely adjusted the operation mode of the power grid, transferred the load of the transmission lines that may be affected by the flood, and organized operation and maintenance personnel to go to the scene for duty and emergency treatment. Due to the timely response, the heavy rainfall did not have any impact on the power grid in the region, and the power supply has always remained stable.
According to statistics, since the introduction of the weather station system, the number of power grid failures caused by bad weather in the region has decreased by 25%, and the blackout time has shortened by 30%, which has greatly improved the reliability of the power grid and the quality of power supply.
Promote the new trend of intelligent power grid development
The application of weather stations in power grids can not only improve the ability of power grids to cope with bad weather, but also provide strong support for the intelligent development of power grids. Through the analysis of long-term meteorological data, power grid enterprises can optimize grid planning and construction, rational distribution of transmission lines and substations, and reduce the impact of bad weather on the grid. At the same time, meteorological data can also be combined with power grid operation data to realize the status monitoring and fault prediction of power grid equipment, and further improve the operation and maintenance efficiency and management level of the power grid.
Industry experts said that with the continuous development of technologies such as the Internet of Things, big data and artificial intelligence, grid-applied weather stations will play a more important role in the future. It will become one of the key supporting technologies for the intelligent transformation of the power grid, and make greater contributions to ensuring the safe and stable supply of electricity and promoting the sustainable development of the energy industry.
With the frequent occurrence of extreme weather events, grid-applied weather stations are gradually becoming an indispensable “secret weapon” for grid enterprises. With accurate weather monitoring and early warning capabilities, it has built a solid defense line for the safe and stable operation of the power grid, and has also brought a more reliable power supply to the majority of users. It is believed that in the near future, this innovative technology will be widely used in more areas and inject new vitality into the development of China’s power grid.
