摘要：
In order to adapt to long-distance and large-capacity transmission scenarios, a system of distant offshore wind DC collection and transmission is proposed, and its development presents new features and trends, bringing serious challenges to its relay protection for DC lines. Firstly, the network configuration of distant offshore wind DC collection and transmission system is clarified, and the special characteristics of relay protection for DC lines in the new system are explained. Secondly, the research results are classified and summarized with regard to the key issues of fault analysis methods, fault identification principles, and fault isolation strategies, and the application scope of existing methods in the new system are clarified. Finally, the technical development trend of the above key issues is foreseen so as to provide support and reference for the research on the relay protection technology for DC lines in the distant offshore wind DC collection and transmission system. © 2023 Science Press.
