摘要
随着新能源并网数量及容量的增加,基于模块化多电平换流器(MMC)的多端直流输电技术由于输出电压谐波含量少、开关损耗低、输电方式更加灵活可靠,成为未来直流输电的发展趋势,文中首先分析了MMC的基本原理,对其拓扑结构、数学模型和主电路参数设计相关研究进行阐述,然后总结了MMC-HVDC的控制策略,最后分析了VSC-MTDC协调控制方法及其工程建设情况。
With the increase of number and capacity of grid-connected renewable energy source,Multi-terminal direct current （MTDC ） transmission system based on Modular Multilevel Converter （MMC ） is becoming the developing trend of high voltage DC transmission system due to such ad-vantages as small harmonic components of output voltage, low switching loss and more flexible and reliable transmis-sion mode.Firstly,the basic principle of MMC is analyzed, and relative researches on its topology structure,mathemati-cal model and parameters design of main circuit are elabora-ted.Secondly,the control strategies of MMC-HVDC are summarized.Finally,the coordination control methods and its engineering construction of VSC-MTDC are analyzed.
