摘要：
随着海上风电场的布局逐步从近海走向远海，以及新型柔性直流(direct current ，DC)输电技术等日趋成熟，在规划设计中研究分散布局的大规模海上风电场集最优输电方式，合理选择先进适用、安全可靠、经济合理的输电技术，为大规模分散式海上风电场输电方式决策提供科学的方法是十分必要的。本文首先分析了海上风电场两种主要输电方式即高压交流输电方式、柔性直流输电方式的技术特点，然后对各种输电方式进行了详细的成本构成分析及计算，并对不同距离和容量下的输电方式做出经济性比
纳米机器人较。最后通过计算得到了海上风电交流/直流输电方式的等价距离，研究结果可为输电规划以及工程设计提供参考。

Abstract: As the layout of offshore wind farms gradually moves from offshore to far sea ，and also with the new flexible DC transmission technology is becoming more and more mature. In the stage of planning and design, it is very necessary to study the optimal transmission mode for the large scale offshore wind farms cluster with decentralized layout, so as to provide a scientific method for selecting the advanced, safe and reliable, economical and reasonable transmission technology. The article analyzed the technical characteristics of two main transmission modes of offshore wind farm,
high voltage AC transmission mode and flexible DC transmission mode, Then the cost composition of various transmission modes is analyzed and calculated in detail, and the economic comparison of transmission modes under different distances and capacities is also made. Finally, the equivalent distance of offshore wind power AC and DC transmission mode is obtained. The design idea of optimal transmission mode for large-scale decentralized offshore wind farms is put forward. The research results can provide reference for transmission planning and engineering design.Keywords: offshore wind power; flexible DC transmission; equivalent distance
