In this paper, an incorporated bridge-type superconducting fault current limiter (BSFCL) and Dynamic Voltage Restorer (DVR) is presented to improve the voltage quality and limiting fault current problems in distribution systems. In order to achieve these capabilities, the BSFCL and DVR are integrated through a common DC link as a BSFCL-DVR system. The FCL and DVR ports of the BSFCL-DVR system are located in the beginning and end of the sensitive loads' feeder integrated to the point of common coupling (PCC) in the distribution system. At first, the principle operation of the BSFCL-DVR is discussed. Then, a control system for the BSFCL-DVR system is designed to enhance the voltage quality and limit the fault current. Eventually, the efficiency of the BSFCL-DVR system is verified through the PSCAD/EMTDC simulation.
本文提出了一种集成桥式超导故障限流器（BSFCL）和动态电压恢复器（DVR），以改善配电系统中的电压质量并解决故障电流限制问题。为了实现这些功能，通过一个公共直流链路将BSFCL和DVR集成在一起，构成一个BSFCL-DVR系统。BSFCL-DVR系统的故障限流器（FCL）端口和DVR端口分别位于与配电系统公共耦合点（PCC）相连的敏感负载馈线的始端和末端。首先，讨论了BSFCL-DVR的工作原理。然后，设计了一种用于BSFCL-DVR系统的控制系统，以提高电压质量并限制故障电流。最后，通过PSCAD/EMTDC仿真验证了BSFCL-DVR系统的有效性。
