The Characteristic Modeling and Short-Circuit Characteristics of the Novel Controllable Line Commutation Valve
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.
