- “故障限流是保证模块化多电平变流器多端直流电网安全运行的关键技术。本文提出了一种基于故障严重程度分类的故障限流器（FCL）和MMC协调控制策略，用于自适应故障限流。所提出的策略减少了FCL的投资，并将无故障线路的母线电压保持在合理值。首先，提出了一种使用初始故障电流信息的快速故障电路参数估计（FCPE）方法。通过这种方法，可以快速估计故障距离和故障过渡电阻，用于定量指示故障严重程度。随后，提出了FCL和MMC的协调控制策略，其中FCL动作优先，而MMC的控制与限流互补。基于所提出的策略，构建了故障严重性相平面（FSPP）来评估故障严重性，并计算FCL的激活时间和MMC的电压调节因子。因此，FCL激活和MMC控制与故障严重程度相匹配。PSCAD/EMTDC中的仿真验证了所提出策略的有效性和优势。”
