| 摘要: |
| 将固态限流器（FCL）与静止同步串联补偿器（SSSC）连接，构成限流式静止同步串联补偿器（SSSC-FCL）。将SSSC-FCL连入直流配电网后，能够改善配电网的电能质量，提高配电网的稳定性。提出了含有SSSC-FCL的双层环状直流配电网拓扑结构，利用PSCAD／EMTDC对提出的拓扑结构进行建模，对直流配电网的正常工况和故障情况进行了仿真。仿真结果表明：SSSC-FCL能够对线路的潮流进行调节；当系统发生故障时，FCL模块能够有效限制短路冲击电流，同时保障非故障线路正常运行，提高了直流配电网的稳定性。 |

| Abstract: |
| SSSC-FCL，a combination of SSSC（Static Synchronous Series Compensator） and ＦＣＬ（Flexible Current Limiter），is applied in DC distribution network to improve its power quality and reliability，for which，a dual-layer-ring topology is proposed. It is modeled with PSCAD／EMTDC and the normal and faulty operations of DC distribution network are simulated. Simulative results show that，SSSC-FCL adjusts the line power flows； during system fault，the short-circuit rush currents of faulty lines are effectively limited by its FCL while the healthy lines keep the normal operation；the reliability of DC distribution network is improved. |
