随着海上风电的发展，直流风电场及其合适的内网拓扑正得到更多的关注。在缺乏实际工程可供参考的情况下，借鉴已有的大型海上交流风电场的经验，拟定可信的海上直流风电场工程算例。从损耗、经济性、可靠性3项经济技术性指标，对适用于高压直流传输的直流风场内网4种不同拓扑结构进行定量的比较分析。分析结果表明，串-并联型和并-串联型内网拓扑可能是未来适用于高压直流传输的海上直流风电场的选择。

With the development of offshore wind power, DC wind farm and its suitable internal grid topology are getting more attention. In the absence of commissioned engineering case, several credible analytical examples of DC wind farm are assumed based on already existing offshore AC wind farm of large scale. The technical-economic indexes of four different internal grid topologies which are suitable for HVDC transmission are quantitatively analyzed and compared related to the power loss, cost and reliability. Analysis results show that the series-parallel and parallel-series topologies may be the option for future offshore DC wind farm with HVDC transmission.
