摘要
为了研发更高电压等级、更高容量的直流输电线路及相关设备,中电普瑞电力工程有限公司完成了1 100 kV特高压直流换流阀的研制。介绍了电气回路、触发与监控系统、换流阀冷却系统、阀塔结构设计,并给出了试验电路拓扑。所研制样机通过了型式试验验证。试验结果表明,该1 100 kV/5 000 A特高压直流换流阀样机可满足工程应用,并具备一定的升级空间。
In order to research and develop the higher voltage, higher capacity HVDC transmission line and HVDC equipment, China-EPRI Electric Power Engineering Co. Ltd has developed a ±1 100 kV UHVDC converter valve. This paper introduces its electric circuit, trigger and monitoring system, converter valve cooling system as well as valve tower structure design, and gives the test circuit topology. The developed prototype has passed the all type tests. The test results show that the ±1100 kV/5 000 A UHVDC converter valve prototype can meet the requirement of engineering application, and it has certain upgrade space.
