• 摘要: 结合我国海上风电场项目的典型条件，对一个装机容量为300 MW，通过交流220 kV线路接入电网的海上风电场的电气主接线方案进行了探讨，提出了海上升压站和高压海底电缆的电压选择方案，集电线路的拓扑布局和集电开关配置方案，主变压器的台数、容量和型式选择方案以及无功补偿的配置方案。对海上风电场电气设计的主要问题提出了建议，为海上风电场电气设计提供了参考。

   

  Abstract: The paper consider a typical condition of the offshore wind farm project in China, which has a capacity of 300 MW, through a 220 kV line connected to the grid. The electrical single line diagram is discussed, then the paper presents the voltage of the offshore substation and the HV-submarine cable, the array cable topology and collector system switch configuration, the main transformer number, capacity and type selection scheme and the reactive power compensation scheme. The views on main problems of electrical design of offshore wind farm are proposed, which provide a reference for the electric design of offshore wind farm.
