Design study on 50 kJ HTS SMES for simulated dynamic experiment of electric power systems

摘要

We conducted a study in order to determine a suitable design for a 50 U class high temperature superconducting (HTS) SMES. Magnet size and volume are expected to be reduced by using the HTS since the HTS wire keeps better properties at high magnetic field than does LTS wire. In this paper, both the electromagnetic and mechanical design objects are considered when optimizing the magnet volume of a 50 kJ/10 kW grid model HTS-SMES system with finite element analysis method and simulated annealing algorithm. We carried out parameter surveys of the magnetic fields and circumference stress applied to the HTS-SMES magnets and studied a suitable magnet dimension with low inductance and high current. 2-3.5 T maximum magnetic field applied to the magnet and a low inductance and high current design for a 50 U HTS magnet are suitable for improving the dynamic response of system.
