A Novel Protection Scheme of AC and DC Line-Touching Based on Coordination of AC and DC Protection

The AC/DC hybrid grid is developing rapidly, and the AC-DC line-touching fault has become an unique fault type. By taking different types of AC and DC line touching faults as the research object, and focusing on the whole process from fault isolation to line reclosing/restarting, the paper explores...
