| 摘 要： | 高温超导限流器(SFCL)是一种限制电网短路电流的有效装置，500 kV SFCL设备研制已有较大发展。对500 kV SFCL接入电网系统的工程的测点与保护配置进行了研究，介绍了SFCL的工作原理，根据三种具有代表性的电气主接线方案，分别提出了相应的测点与保护配置，并讨论了保护间配合以及重合闸等相关问题。经分析对比，得出了对电网运行可靠性影响较小的方案，论证了SFCL在测点与保护配置方面的可行性，为相关工程的实施提供了技术准备。

| Abstract: | Superconducting fault current limiter (SFCL) is an effective measure to limit short circuit current in power grid. The equipment research and development of 500 kV SFCL have been greatly developed. This paper made a study on measure point and protection configuration for 500 kV SFCL. Firstly, working principle of SFCL was introduced. Then based on the three major single line diagrams, the corresponding measure point and protection configurations were proposed. Finally, the cooperation between different protection schemes was discussed. Compared with the analysis, the scheme causing the lower affect to the reliability of power grid is found. The feasibility of the SFCL in the measure point and protection configuration is demonstrated, which has provided technical preparation for the implementation of the relevant projects. |
