摘要：
The inverter topology transformation is an attempt to completely solve the problem of commutation failure (CF) from the perspective of devices. However, the current related research ignores the switching characteristics of the device, resulting in the unclear turn-off model, and it is impossible to accurately determine the recovery process of the blocking ability of the thyristor and analyze the mechanism. Based on the consideration of the device level, this paper analyzes the reasons for the commutation failure, and studys a structure in which semi-controlled and fully-controlled devices are connected in series. First of all, this paper analyzes the current flow path of the coupled turn-off process, and then establishes the coupled turn-off characteristic model and analyzes its mechanism in detail. Then, based on the mechanism, a coordination strategy of semi-controlled and fully-controlled devices in series considering the blocking characteristics of the devices is proposed. Finally, in the simulation, the effectiveness of coupled turn-off process model and the coordination strategy are verified, and the effect of the semi-controlled and fully-controlled device series structure on the suppression of CF of the dual-infeed HVDC transmission system is analyzed. ©2023 Chin.Soc.for Elec.Eng.
