摘　　要：风能作为一种可再生的清洁能源,有望成为传统能源的替代品,海上风电成为未来风电发展的趋势。针对海上风电场的并网方案进行研究,分析了交流并网方案和直流并网方案的拓扑结构。对比两种方案,当输电距离较短时,采用交流并网更优;输电距离较长时,采用直流并网更优。以一个500 MW风电场为例,从对比分析两种并网方案的投资成本和损耗出发,验证了交流并网更适用于近海电场、直流并网更适用于远海电场的结论。Wind energy,as a kind of renewable and clean energy,is expected to be the substitute of the traditional energies,offshore windfarm has been a trend. In the article,the integration scheme of windfarm is discussed,different topologic scheme of AC and DC integration is compared. According to comparison,when the distance is short,AC integration is better; while the distance is long,DC integration is prior. For a offshore windfarm with a capacity of 500 MW,the costs and losses of the two integrations are compared,drawing the conclusion that AC integration is better for locate offshore windfarm and DC integration is better for offshore windfarm.
