Study on service test procedure for SMES systems

Abstract Some superconducting magnetic energy storage (SMES) systems have been developed successfully, and the function of them was verified by experiment. Considering the impact on the system security and stability when they are connected to the power system, it is important to build a standard test procedure and propose the main experimental contents for some representative superconducting devices. Based on the experimental results of a 35 kJ/7 kW conduction-cooled high-Tc SMES system, which was developed by Huazhong University of Science and Technology, the test items and methods for a conduction-cooled high-Tc SMES system are studied. For performance evaluation of this high-Tc SMES, three superconducting magnet performance tests, power conditioning characteristic test and dynamic experiment in a simulated power system were fulfilled.
