摘要: |
针对传统母联开关的各种缺陷,提出了一种基于模块化多电平变换器拓扑的柔性母联控制器。它可以连接不同电压等级的网络,实现潮流的优化调节、无功支撑及故障时交流系统之间的快速紧急支援和隔离故障。同时具备直流电压输出端口,可以用于交直流混合的配电网架中。对柔性母联控制器的工作模式进行了分析,设计了直流电压及潮流控制器。通过仿真及实验,验证了该控制器的性能。 |

Abstract: |
For a variety of defects of the traditional coupling switch, a flexible coupling switch based on modular multilevel converter topology is proposed. It can connect the networks with different voltage levels, achieve optimal regulation of power flow, reactive power compensation, and emergency support and rapid fault isolation between fault AC system, and meanwhile has DC voltage output port which can be used in AC and DC power distribution networks. The operating mode of the flexible coupling switch is analyzed, and DC voltage and power flow controller are designed. Finally, simulation and experiment results verify the performance of the switch.
