From the viewpoint of global new energy development

offshore wind power (OWP) is the main battlefield and is developing towards large-capacity

clustered

long-distance. Voltage source converter based high voltage direct current transmission (VSC-HVDC) is still the mainstream transmission method and hot research direction for large-capacity and long-distance wind power integrating. In this paper

firstly

overview of key projects in operation

construction in process

and planning of VSC-HVDC for OWP are introduced. Then

the typical DC topology

AC collection for offshore wind farms

key electrical equipment of converter stations

and the control and protection technology are introduced

and the research status and engineering applications are summarized. Finally

the development directions and challenges are pointed out

including the research and development in compact and lightweight key equipment and offshore platform of VSC-HVDC for large-capacity and long-distance OWP

the research on topology structure and networking technology of VSC-HVDC for OWP under offshore-onshore integration

real-time measurement of broadband impedance

improvement of oscillation online evaluation technology

exploration of other new transmission technologies

etc.
