摘　　要：频率适应性是交流保护装置适应直流孤岛方式运行的重要特性,对直流孤岛稳定运行起到了重要作用。建立直流孤岛运行系统RTDS仿真模型,并将其与实际控制保护装置连接组成闭环实时仿真试验系统。通过设置多种试验项目,开展不同种类交流保护装置频率适应性试验研究,发现了直流孤岛运行方式下交流保护装置误动或拒动缺陷,为交流保护装置适应直流孤岛运行提供了重要的参考依据。The frequency adaptability of AC protective equipment is an important performance in the islanding mode of HVDC operation,which plays an important role in the stable operation of islanded HVDC system. An RTDS simulation model of HVDC system operating in islanding mode is built and connected with an actual control-protection device to form a real-time closed-loop simulation-test system. A variety of test items are set to research the frequency adaptability for different types of AC protective equipment and different defects of AC protective equipment in the islanding mode of HVDC operation are revealed,which provides an important reference for the operational adaptability of AC protective equipment to the islanded HVDC system.
