超导磁储能系统（superconducting magnetic energy storage，SMES）能够实现与电网之间的快速功率交换，对于增强电网稳定性，改善电能质量具有重要意义。本文针对一套100 kJ/50 kW高温超导磁储能系统，对其超导磁体设计与低温系统，功率调节系统的拓扑及控制策略设计、主监控系统的设计分别进行了阐述和分析。为了验证整个磁储能系统的性能，进行了相关的开环功率调节实验。实验结果表明，整套系统运行良好，SMES能够快速的响应主监控系统发出的功率指令，实现SMES与电网之间快速的功率交换。基于上述对SMES的分析和实验测试，结合云电科技园微电网的拓扑，给出了几种 SMES 在微电网中应用的试验方案，以验证 SMES在微电网中应用的性能和作用。

Superconducting magnet energy storage system (SMES) can achieve quick power response with the power grid, which can enhance the stability of power grid and improve the power quality. This paper introduces a 100 kJ/50 kW SMES including the superconducting magnet design, the cooling system, power conditioning system and the monitored control system. In order to verify the performance of this SMES, open-loop power regulation experiments are conducted. The following conclusions can be achieved through the above experiments, that SMES can respond very quickly to exchange power with the power grid. Based on the above analysis and tests and taking the topology of micro-grid demonstration garden of Yunnan electric power grid into consideration, experiment schemes are presented for the application of SMES in micro-grid, which aims to verify the performance and function of SMES when it is applied in micro-grid.
