摘　　要：阀冷系统在直流输电过程中具有重要作用,现有控制保护系统对阀冷设备潜伏性故障的预判能力仍显不足,亟须通过数字化手段加强对设备的有效监测。本文基于现有数字化试点站的建设经验,介绍数字化平台的数据来源,针对现有阀冷控制保护设备智能化不足的缺点,提出应用数据分析预测、主循环泵健康评估、阀冷系统健康评估、渗漏预警、故障诊断等数字化技术,以减少换流站运行成本和故障处理时间,提高电网的运行可靠性。Valve cooling system plays an important role in DC transmission engineering.The current control and protection systems still lack the ability to make predictive judgments on potential faults in valve cooling equipment,and there is an urgent need to strengthen effective monitoring of equipment through digital means.Based on the experience of existing digital pilot stations,this paper introduces the data sources of the digital platform,and at the same time,aiming at the shortcomings of the lack of intelligence in existing valve cooling control and protection equipment,it proposes applications of digital technologies such as data analysis prediction,health assessment of the main pump,health assessment of the valve cooling system,leakage warning,and fault diagnosis,to reduce the operating costs and fault handling time of converter stations,and improve the operational reliability of the power grid.
