Current trajectory image-based protection algorithm for transmission lines connected to MMC-HVDC stations using CA-CNN

Abstract In the presence of an MMC-HVDC system, current differential protection (CDP) has the risk of failure in operation under an internal fault. In addition, CDP may also incur security issues in the presence of current transformer (CT) saturation and outliers. In this paper, a current trajectory...
