国际领先 中国首创 世界首台新型换流阀在河南投运

Core Viewpoint - The successful operation of the new HCC converter valve marks a significant breakthrough in addressing the "commutation failure" issue that has plagued the global DC transmission sector for over half a century [1][2]. Group 1: Technology and Innovation - The new HCC converter valve, developed entirely in China, is the world's first based on IGCT devices and has completed a 168-hour trial run before being put into commercial operation [1]. - This technology allows for precise current recognition and rapid disconnection within microseconds, fundamentally solving the "commutation failure" problem [1][2]. - The product has been recognized as reaching international leading performance levels and is included in key national technology promotion directories [2]. Group 2: Industry Impact - The HCC converter valve is expected to enhance the stability of the Henan power grid and increase the proportion of renewable energy transmitted, supporting the construction of a new power system and the achievement of carbon neutrality goals [2]. - The Lingbao back-to-back converter station, where the new valve is installed, has been operational for 20 years and has transmitted over 130 billion kilowatt-hours of electricity, significantly reducing coal consumption and carbon emissions in the region [2].
