[The world's first 500 kV economical high voltage AC current limiter] A few days ago, the world's first 500kV/90kA economical high-voltage AC current limiter developed by China Xidian Group successfully completed the manual short-circuit test and was successfully put into operation on the Shun-Guang-A line of the 500kV Guangnan Station. The successful operation of the project has filled the domestic economical AC ultra-large short-circuit current suppression technology gap, provided an economical and reliable solution for the suppression of high-voltage AC short-circuit current, and provided a strong guarantee for the reliable operation of the ultra-high-voltage large power grid.

• [The intelligentization of Shanxi coal mines will be basically achieved by 2027]
• Shanxi recently issued the "Implementation Plan for Accelerating Energy Green and Low Carbon Transformation and Development", aiming to promote the construction of the energy system and high-quality economic development. The plan proposes to focus on building intelligent green coal mines with a capacity of over 1.2 million tons per year, accelerate resource allocation and transfer, and exit inefficient production capacity. At the same time, it is required that production coal mines that meet the conditions by 2027 achieve basic intelligence, cultivate artificial intelligence application scenarios, continuously improve safety assurance levels, and fully guarantee the stable supply of national electricity coal.
