我国自主研发的新型混合换相换流阀在河南投入运行

Core Viewpoint - The successful commercial operation of a new generation hybrid commutation converter valve, developed based on IGCT devices, marks a significant breakthrough in addressing the "commutation failure" issue in the DC transmission sector [1] Group 1: Technology Development - The new hybrid commutation converter valve was put into commercial operation at the State Grid Corporation's Lingbao back-to-back converter station in Henan [1] - This technology allows for precise current identification and rapid disconnection within microsecond timeframes, featuring a "fully controlled" characteristic that resolves the "commutation failure" problem [1] Group 2: Industry Impact - The hybrid converter valve represents a shift from traditional thyristor converter valves, which are limited by their "half-controlled" nature, leading to risks during AC-DC conversion [1] - The development involved collaboration among the State Grid Corporation, Tsinghua University, Huairou Laboratory, and China Electric Equipment Group, showcasing a significant achievement in independent innovation from core components to integrated systems [1]
