大规模海上风电并网方式的研究

摘要

在风力发电等可再生能源技术高速发展的潮流下,对比分析了适用于海上风电场的高压交流、常规高压直流和柔性直流输电3种并网方式.简要介绍了柔性直流输电的工作原理,详细说明了柔性直流输电技术在风电并网上的应用情况,并着重探讨柔性直流输电并网的经济性,认为柔性直流输电技术在海上风电传输领域有广阔应用前景.这对于满足我国清洁高效的能源利用有着显著的意义.%In the context of the rapid development of wind power and other renewable energy technology,this paper comparatively analyzes the three different modes of power transmission of off-shore wind farm: HAVC,LCC-HVDC and VSC-HVDC.The working principle of VSC-HVDC transmission system is introduced briefly;the application of VSC-HVDC technology in wind power grid integration is described in detail,emphatically its economy.It indicates that the application of VSC-HVDC in the field of off-shore wind power transmission has broad prospect and great significance of meeting the needs of clean and efficient energy use in China.
