摘要: 为提高海上风电的经济性,更充分地利用海上风电资源,提出与海上风电直流输电相关的海上风电高压直流输电及直流汇集技术。结合不同连接方式与不同的系统升压次数,从中优选出契合当下海上风电发展趋势的海上风电直流汇集升压拓扑结构,分析典型海上风电出力场景下直流汇集系统中各拓扑结构的特性,并结合典型案例研究各拓扑结构的建设成本、能量损耗与可靠性,进而得出最适用于大型海上风力发电场的直流汇集方案构型,以提升海上风电直流汇集系统的综合效益。

Abstract: To enhance the economy of offshore wind power and make fuller use of offshore wind power resources, high-voltage direct current transmission and DC aggregation technologies related to offshore wind power DC transmission is proposed. Combining different connection methods and different system boosting times, the topology of offshore wind power DC aggregation and boosting is selected to meet the current development trend of offshore wind power, and the characteristics of each topology in the DC aggregation system under typical offshore wind power scenarios are analyzed. The construction cost, energy loss and reliability of each topology are studied in conjunction with typical case studies. Finally, the most suitable DC aggregation scheme configuration for large-scale offshore wind farms is then derived to improve the comprehensive benefits of the offshore wind power DC aggregation system.

Key words: offshore wind power, DC aggregation and boosting system, topology, economy, energy loss, reliability
