摘要
柔性直流输电技术近年来在国际和国内电网得到广泛发展和应用,新型技术层出不穷。在总结国内外柔性直流输电的典型工程及技术应用现状的基础上,梳理了国内电网柔性直流接入场景和技术需求,结合不同型式柔性直流的性能特点,提出了匹配不同场景需求的柔性直流应用型式选择方法;结合电网实际,指出了应用柔性直流输电技术时需关注的新问题。为电网规划阶段合理选择柔性直流应用场景,以及该场景下柔性直流合理应用型式选择提供了有效的解决方案。
Voltage-source-converter based high-voltage direct current(VSC-HVDC)transmission technology has been widely developed and applied in the world and China’s power grid in recent years,and new technologies emerge in endlessly.On the basis of summarizing the typical engineering and technical application status of VSC-HVDC at home and abroad,this paper combs the VSC-HVDC access scenarios and technical requirements of China’s power grid,combines the performance characteristics of different types of VSC-HVDC,and puts forward the method for selecting application type matching different scenario requirements.Combined with the actual power grid,the new problems that need to be paid attention to are pointed out when applying VSC-HVDC technology.An effective solution is provided for the rational selection of VSC-HVDC application scenarios in the planning stage of the power grid and the selection of reasonable application type of VSC-HVDC.
