“…The magnet of the developed SMES consists of 32 Bi-2223/Ag tapes, and designed as solenoid type according to the capacity of the magnet, the requirements of power regulation and the conduction-cool cryogenic unit [22]. The tape can operate with 3 T at 20 K. Therefore, the magnet can operate with fast current ramps, which is important for dynamic power compensation [23]. The specifications are given in the appendix.…”

This paper introduces the first movable conductioncooled high temperature superconducting magnetic energy storage (SMES) system developed in China. The SMES is rated at 380 V / 35 kJ / 7 kW, consisting of the high temperature magnet confined in a dewar, the cryogenic unit, the converter, the monitoring and control unit, and the container, etc. The proposed SMES can be loaded onto a truck to move to a desired location and put into operation with easy connection. Laboratory and field tests have been carried out to investigate the operational characteristics and to demonstrate the SMES' effectiveness on improvements of system voltage stability and on the oscillation damping. Test results indicate that the SMES system has the features of fast response and four-quadrant power operation. The accessories for the movability of the SMES system are well designed. The system is feasible to be used in power systems.Index Terms--conduction cool, high temperature superconducting, moveable SMES, power system transient stability, superconducting magnetic energy storage Jiakun Fang received the Ph.D.

This paper outlines a systematic procedure for the design of a toroidal magnet for Superconducting Magnetic Energy Storage System and presents the optimum design for a 10 MJ class high temperature superconductor (HTS) magnet. The main magnetic component which influences the maximum critical current was investigated. Stray field and operating current needed in a toroidal magnet with different number of elemental coils were compared too. Based on above analysis, both electromagnetic and mechanical design objects were considered when optimizing the volume of HTS Superconducting magnet with optimal number of toroidal elements with Finite Element Method. Parameter surveys of the magnetic fields and electromagnetic stress applied to the HTS magnets were carried out and a suitable magnet dimension with low inductance and high current was studied. The results verify that the double pancake type is more favorable for actual design and operation.
