摘要(Abstract):
舟山多端柔性直流输电示范工程是世界首个五端柔性直流工程,在工程设计中存在着电缆选型复杂、与其他管线的交越、敷设保护等与常规直流输电工程不同的技术问题。以本工程定海-岱山段为例,通过详细分析、计算,提出了相关技术原则和方案,并获得工程应用。
Zhoushan multi-terminal flexible DC demonstration project is the first five-terminal flexible DC project in the world. In the engineering design, cable type selection, crossover with other pipelines and laying protection are different from those of conventional DC power transmission projects. By taking Dinghai-Daishan section of the project as an example and through detailed analysis and calculation, the paper proposes relevant technical principle and scheme, which turned out to be successful in engineering practice.
