| Popis: | High-energy high-temperature superconducting superconducting magnetic energy storage (HTS-SMES) is expected to play an important role in stabilizing the future smart micro grid. Large-scale and high-field magnet is required for high-energy SMES. However, the significant hoop stress induced by the Lorentz force has become one of the most serious threats. In this paper, we proposed a solution to reduce the hoop stress by overbanding the solenoidal magnet with high Young's modulus and yielding strength reinforcing structure. A unique graphical method was developed to optimize the geometry of the magnet and reinforcing overbanding structure to achieve high energy capacity. According to our analysis, thin-walled solenoid with large aperture is recommended as an economical geometry for HTS-SMES. |
