摘　　要：基于海上风电场输电系统模型和海底电缆参数,分析了海上风电场无功补偿配置方法和海缆损耗的计算方法,建立了海上风电场输电系统简化模型,计算了不同规模、不同传输距离海上风电场采用两端补偿和陆上单端补偿两种方案时输出海缆导体损耗,得到了海缆导体损耗-风电场出力曲线。在风电场低出力水平及长距离传输时,两端补偿损耗更低,而在风电场高出力水平或短距离传输时,单端补偿损耗稍低一些。Based on the transmission system model and submarine cable parameters of offshore wind farm, the reactive power compensation configuration mode of offshore wind farm and the calculation method of submarine cable loss were analyzed. A simplified model of offshore wind power transmission system was established; and the output cable loss under two different compensation schemes： both ends compensation and single-end compensation on land, were calculated for offshore wind farms with different scales and transmission distances; the power loss-wind farm output curves of submarine cable were obtained. Both ends compensation will have a lower cable power loss when the wind farm is in the low output level or with long distance transmission, while single-end compensation will have a little lower cable power loss when the wind farm is in the high output level or with short distance transmission.
