Fault Mechanism Analysis and One-terminal Protection Method of Flexible DC Transmission Line under the Influence of Multi-type Faults

Multi-terminal flexible DC transmission line protection faces various fault types and is susceptible to factors such as transition resistance and noise. To address this, a fast-action protection method for the entire flexible DC line using single-ended voltage gradient energy values is proposed, whi...
