摘　　要：对新型可控换相换流器投产后人工接地短路试验的情况进行了研究,介绍了可控换相换流器的工程化建模和工作原理,对比了自然换相和可控换相2种工作模式下短路特性的差异。对比结果表明,可控换相换流器可以在交流侧电压大幅度波动时维持功率传输,有助于系统频率恢复和系统稳定。This article presents a study on the artificial grounding short-circuit test of a novel controllable commutation converter after it is put into operation.The engineering modeling and working principle of the controllable commutation converter are introduced,and the differences in short-circuit characteristics between natural commutation and controllable commutation modes are compared.The comparison results show that the controllable commutation converter can maintain power transmission when the AC side voltage fluctuates significantly,which is helpful for system frequency recovery and system stability.
