摘要
模块化多电平换流器型高压直流输电(MMC-HVDC)系统向无源网络供电是MMC-HVDC技术的一个重要应用领域,因此有必要对向无源网络供电的MMC-HVDC系统的控制器进行设计,为此,基于MMC拓扑结构,推导了MMC数学模型,并由此设计了整流侧和无源网络侧的控制器,仿真结果验证了所设计控制器的正确性,且表明MMC-HVDC系统向无源网络供电是一种比较理想的输配电方式。
It is an important application domain to supply passive network by MMC-HVDC system,so it is necessary to design a controller for MMC-HVDC system connected to passive network which should be proved by simulation in detail.Basing on the topology structure of MMC,we derived a mathematical model of MMC,designed a controller at rectification side and passive network side,which was proved to be correct by simulation results.The simulation shows it is a good transmission and distribution way to supply passive network by MMC-HVDC system.
