摘要

随着向家坝—上海、云南—广东等多项±800 kV特高压直流输电工程的顺利建成

中国在特高压直流输电线路的建设和工程运行过程中积累了丰富的经验。为了满足中国国民经济的飞速发展对电力能源的需求

建设更大输送容量的直流工程将成为下一步直流输电工程建设发展的必然趋势

而系统电压等级的提高又对换流阀产品性能提出了更高要求。用于±1 100 kV特高压直流输电工程的换流阀产品

其单级晶闸管元件运行试验最高触发电压和恢复电压分别达到5.5 kV和3.3 kV

试验电流和短路故障电流分别为5 332 A和50 kA。为保证系统运行安全

换流阀产品在投运之前

必须通过型式试验对其性能进行验证。西安高压电器研究院有限责任公司利用换流阀运行试验合成回路

模拟±1 100 kV特高压直流输电工程用换流阀在实际运行中的各种工况

完成了试品阀的运行型式试验

并对得到的试验数据进行了分析

为±1 100 kV特高压换流阀产品的设计、制造及工程运行和试验标准的制定提供了参考依据。

Abstract

As the Xiangjiaba-Shanghai project and Yunnan-Guangdong ±800 kV UHVDC power transmission projects successfully completed

the rich experiences of project construction and operation have been accumulated.It is a necessary trend to construct projects with more transmission capacity

and the increase of the voltage class will brings up higher requirements for the performance of the thyristor valves.For the valves designed for ±1 100 kV UHVDC power transmission projects

the firing voltage and the recovery voltage applied on per thyristor level are up to 5.5 kV and 3.3 kV while the continuous operating current and the fault current are up to 5 332 A and 50 kA.So the type test must be done to check the performance of the valves for the system safety.The valves operation test has been undertaken by XIHARI in synthetic test circuit

and the test data have been checked and analyzed.The references for the design

manufacture

operation and the standards redaction of the thyristor valves have been provided.
