摘要(Abstract)：

与现有的海上风电场相比,采用直流技术汇集电能和并网的海上直流风电场无需使用笨重且体积庞大的工频交流变压器,也无需对电能进行多次整流、逆变和升压,因而在设备的体积和质量、系统损耗及建设成本等方面均具有明显优势。首先对串联升压型和辐射型2种主要类型的海上直流风电场进行了详细综述,包括其拓扑结构、控制策略、优势和存在的问题;然后详细分析了海上直流风电场的关键设备——高电压、大容量、高增益DC/DC变换器的研究现状,指出了各类DC/DC变换器的优缺点及其在海上直流风电场中的应用前景;最后对海上直流风电场的故障保护问题和经济性问题的研究情况进行了总结。所述内容对中国开展海上风电等海洋能的开发利用具有一定参考价值。
