AI Technical Summary
There is a lack of existing technologies that can directly connect offshore wind power to a distant DC grid using existing mature AC wind turbines and AC power collection technologies. This is especially true when wind farms are close to the coast. How to achieve power conversion and grid connection on land is a challenge. Furthermore, the construction of existing offshore converter stations is costly and difficult, which affects economic efficiency.
Design an offshore wind power DC grid-connected converter station, including an AC field, converter valve hall, bridge arm reactor and start-up area, DC circuit breaker and energy dissipation valve hall and DC field. Through compact layout, the offshore wind power AC collection line can be directly converted into DC power and connected to the DC grid after landing, eliminating the need for construction of an offshore converter station.
It enables large-capacity offshore wind power transmission, reduces construction costs and land area, simplifies system structure, and improves system availability and economy.
