摘要
结合特高压直流输电工程换流阀冷却系统的实际应用环境,介绍了阀冷控制系统的关键作用及其供电电源的重要性。同时,分析了阀冷控制系统直流供电回路的设计现状以及存在的缺陷和风险,并针对其中的双电源切换回路和直流母线提出了优化设计方案。
Combined with the practical application environment of the converter valve cooling system of UHV DC transmission project,the key role of the valve cooling control system and the importance of its power supply are introduced.At the same time,the design status,defects and risks of the DC power supply circuit of the valve cooling control system are analyzed,and an optimized design scheme is proposed for the dual power supply switching circuit and the DC bus.
