摘　　要：海上风电场升压站电气设计遇到的首要难题，是在有限的海上平台上布置各种电力设备，如：220kV（或110kV）、35kV、0．4kV配电设备、控制系统、通信系统等设备。解决这一问题的有效的办法之一，是合理配置海上风电场的无功补偿设备。最切实可行的方法是充分挖掘风电机组的无功容量和调节能力，以大幅度地减少安装于升压站的集中型无功补偿装置的容量。在理想情况下，集中型无功补偿装置的容螬可能缩减至零。The chief problem in electric power design of offshore wind farm substation is the arrangement of electric power devices, such as electrical equipments of various voltage level, control system, and communication system, in limited space of the platform. Reasonable configuration of reactive power compensation devices in offshore wind farm is an effective way to solve this problem. The most practical and feasible method is to fully exploit reactive power capacity and regulation ability of wind turbines, so as to greatly reduce the capacity of centralized reactive power compensation devices. Ideally, this capacity could be reduced to zero.
