| 摘要: |
| 在对电阻型超导限流器失超机理及失超过程进行深入分析的基础上，利用PSCAD仿真软件搭建了电阻型超导限流器的自定义模型，并通过仿真该模型的电阻、电流和温度曲线验证自定义超导限流器模型的正确性。对超导限流器与继电保护装置的配合问题进行了初探。理论分析及该模型的实例验证表明，模型较全面地呈现了限流器真实的工作状态。将其投入10 kV配电网中的仿真结果表明，超导限流器不仅对系统短路电流有显著的限制作用，同时还有利于改善非故障馈线的供电电压质量。为了与继保装置配合，选择最优的超导限流器参数将对限流器的挂网运行有重要参考价值。 |

| Abstract: |
| Based on the study of resistor-type SFCL（Superconducting Fault Current Limiter），a SFCL model is established by PSCAD，which is verified by simulating the curves of resistance，current and temperature. The coordination of SFCL and relay protection is preliminarily investigated. Theoretical analysis and case study show that，the established model fully represents the real working states of SFCL prototype. The simulation of its application in a 10 kV distribution network shows that，SFCL limits the short circuit current significantly and improves the power supply quality of healthy feeders. The selection of optimal SFCL parameters for its coordination with relay protection is helpful to its practical operation. |
