摘要
舟山多端柔性直流输电示范工程是世界范围内首个五端柔性直流输电工程,在不同条件下运行方式复杂多变。首先简要介绍了舟山交直流混联电网特点及示范工程定位;然后分析了示范工程典型运行方式和部分高级功能,如多换流站协调控制功能、联网模式与孤岛模式平滑切换等功能;最后介绍了示范工程现场试验和实际运行情况。运行实践表明,示范工程运行方式灵活,显著提高了舟山电网特别是舟山北部电网供电可靠性,经济效益和社会效益显著。
Zhoushan multi-terminal VSC-HVDC pilot project is the first five-terminal VSC-HVDC project in operation over the world andits operating mode varies greatly under different conditions. Firstly, characteristics of Zhoushan hybrid AC/DC power grid and functional orientation of the project are presented. Secondly, typical operating modes and advanced functions, including coordination strategies of multiple converters and smooth transition between grid-connected and islanded modes, are analyzed. Finally, field tests and operational performance after commissioning are presented. Overall operational performance demonstrates that the project works well and enhances reliability of Zhoushan power grid greatly, especially for Zhoushan north power grid. It provides vital economic and social benefit.
