设计并制作了一个4kJ传导冷却高温超导脉冲线圈。线圈采用Bi-2223银合金护套多芯线组成的层间换位6股平行导线绕制。我们开发了一套完整的3.6 MJ/1 MW低温超导（LTS）SMES系统，用于在Imajuku变电站的电力线上进行测试。针对超导磁储能系统采用高温超导线圈运行的可行性，提出了一种将高温超导线圈串接在3个低温超导线圈上的超导磁储能系统。包括高温超导线圈的SMES连接到Imajuku变电站的电力系统，在6 kV电力线上进行负载波动补偿的运行试验。试验结果表明，高温超导磁储能系统在未来电力系统中的应用是可行的。
We designed and fabricated a 4 kJ conduction-cooled high-Tc superconducting (HTS) pulse coil. The coil is wound with an interlayer-transposed 6-strand parallel conductor which is composed of Bi-2223 silver alloy-sheathed multi-filamentary wires. We had developed a complete 3.6 MJ/1 MW low-Tc superconducting (LTS) SMES system for testing on a power line at Imajuku substation. Aiming at the feasible operation of SMES applying a HTS coil, we made a SMES system set-up in which HTS coils were serially connected to 3 LTS coils of the SMES. The SMES including the HTS coil was connected to Imajuku substation's power system, to made operational tests of compensation for load fluctuation at the 6 kV power line. The test results lead to the feasibility of the HTS SMES for practical use in future power systems.
