摘　　要：±800 kV直流输电工程电压等级高,额定电流大,并且采用世界上首次在工程中采用的6英寸晶闸管。为了对800 kV换流阀进行有效的试验,采用了利用新开发的一套合成回路对800 kV换流阀进行试验的过程,试验可以模拟换流阀在实际运行中的各种运行状态。得到了向上工程换流阀运行试验的相关结果。试验结果证明向上工程换流阀设计完全满足要求,所有参数均高于工程设计水平。Three Xiangjiaba-Shanghai ±800 kV HVDC thyristor valves have a high power rating per thyristor level. For the purpose of verifying the valve design in operating test. Testing of these thyristor valves by using a synthetic test circuit is necessary. The conditions of all operational states of HVDC thyristor valves can be adequately represented in this synthetic test circuit. The successful type test results show that the design of XS HVDC thyristor valves is fully adequate. The tested nodules also show a substantial margin in the thyristor valve design since, for most of the tests, the test parameters were globally more severe than the specified.
