超导储能(SMES)系统是一种储存和瞬时释放大量电能的装置。它将能量储存在磁场中，该磁场是由低温冷却的超导材料线圈中的直流电流产生的。SMES可以在几分钟内充电，并可以重复充放电序列数千次，而不会对磁体造成任何退化。介绍了一种用于SMES系统的7.3kJ传导冷却高温超导(HTS)磁体。该磁体由15个薄片线圈组成，用Bi2223高强度线材缠绕，在35K时的临界电流为140A。
Superconducting magnetic energy storage (SMES) system is a device for storing and instantaneously discharging large quantities of power. It stores energy in the magnetic field generated by the flow of DC current in a coil of superconducting material that has been cryogenically cooled. The SMES recharges within minutes and can repeat the charge/discharge sequence thousands of times without any degradation of the magnet. This paper described a 7.3 kJ conduction – cooled, high – Tc superconducting (HTS) magnet for SMES system. This magnet consist of 15 pancake – coils wound with Bi-2223 High Strength Wire with critical current 140 A at 35 K.
