摘要

换流阀是特高压直流输电工程中主要关键设备

其设计的可靠性直接影响直流系统的安全可靠运行。文中介绍了锦屏—苏南±800 kV特高压直流工程晶闸管换流阀主要技术参数。主要从电压应力、电流应力、水冷系统、晶闸管参数4个方面和先前投运的向家坝—上海±800 kV特高压直流工程晶闸管换流阀进行了对比分析。验证了锦屏—苏南特高压直流工程晶闸管换流阀整体性能比向家坝—上海±800 kV直流工程有所提升

可以长期安全可靠运行;同时也为后续±800 kV特高压直流工程换流阀的设计和制造奠定了良好的基础。

Abstract

For a UHVDC project

the reliability of the thyristor valves is related to safe operation of the UHVDC system. In this paper

the main parameters of the thyristor valves

which were designed and manufactured by XDPS for the Jinping-Sunan ±800 kV UHVDC project

are introduced. And these thyristor valves are compared with those used in the Xiangjiaba-Shanghai ±800 kV UHVDC project in terms of voltage stress

current stress

water cooling system and thyristor performance. The comparison indicates that the present thyristor valves achieve better overall performance

and can operate safely and reliably in a long term.
