| 摘要: |
| 针对故障限流器高速性、高实时性的应用需求，设计并研制了一套基于嵌入式平台的故障限流器控制系统。系统采用模块化设计，硬件部分包括数据采集单元、主控单元和子模块控制单元三部分，其中主控单元中的核心控制模块采用高性能DSP和FPGA的硬件模式。软件部分包括故障识别模块、状态监测模块和逻辑控制模块，其中故障识别模块采用基于短数据窗的幅值计算方法，对控制逻辑及相关定值也进行了详细设计。通过型式试验和数模仿真试验验证，控制系统能够快速识别短路故障并控制故障限流器动作，为故障限流器的工程应用奠定基础。 |

| Abstract: |
| Aiming at the high-speed and high-real-time application requirements of fault current limiter, the control system based on embedded platform is designed and implemented in this paper. In modular design, the hardware includes three parts:data acquisition unit, main control unit and sub-module control unit. High-performance DSP and FPGA are adopted in the core control module. The control software consists of fault identification module, state monitoring module and logic control module. The fault identification module adopts amplitude calculation method based on short data window and the control logic and its related settings are also designed in detail. Through type test and RTDS test, the system can quickly identify short-circuit fault and control the fault current limiter, which lays a foundation for the engineering application of fault current limiter.
