摘　　要：中国电力科学研究院成功研制了具有完全自主知识产权的800 kV/4 750 A特高压直流换流阀,并通过了型式试验。分析换流阀研制所涉及的基础理论和关键技术。从工作原理、运行工况、电气拓扑和宽频模型等角度完成对换流阀的物理解构;研究换流阀设计开发工作所涉及的暂态电磁特性分析技术、非线性组件协调配合技术、晶闸管反向恢复过程的解析逼近与动态仿真模型、抗震设计技术、换流阀系统热力场分析与冷却技术、自适应换流阀触发监控系统等系列关键技术。从关键零部件、阀模块样机及阀塔样机研制3个层面分析换流阀样机的主要设计理念、设计原则和技术特点。The China＇s first ±800kV/4750A HVDC converter valve has been successfully developed by CEPRI with independent intellectual property rights, and it has passed type tests. This paper mainly focused on fundamental theories and key technology analysis. From the distinct angles including the working conditions, the electrical topology and the broadband model, this paper has completed the physical deconstruction of the value. Meanwhile, the paper has studied a series of key technologies, such as the transient electromagnetic characteristic analysis, the nonlinear component coordination technology, the reverse recovery process analytical approximation and the dynamic simulation model of thyristors, the seismic design, the converter valve system thermal field analysis, the cooling technology, the adaptive commutation valve triggering monitoring system and other series of key technologies. Besides, from three distinct layers, the key parts, the valve module prototype and the valve tower prototype, the paper has also analyzed the main design principles and technical features for the converter valve prototype.
