AC Loss Analysis of a Single-Solenoid HTS SMES Based on H-formulation

[摘要] There will be much AC loss generated when a superconducting magnetic energy storage(SMES) is applied in a power system to exchange power with a power network or other equipment. AC loss may cause the instability and risk of burnout to SMES. This paper presents a commonly used SMES design scheme and lists the design parameters of a 10MJ/5MW SMES. We used the finite element software COMSOL to build a simulation model to calculate the AC loss during its operation. We get the calculated results and analyse AC loss's distribution characteristics of the 10MJ/5MW SMES which uses a single screw structure.
