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. |
