Voltage Distribution Characteristic of HTS SMES Magnet

HTS superconducting magnetic energy storage (SMES) system can be utilized to ensure stable operation and high-quality power supply in power systems. In SMES system, the power conditioning system (PCS) interfaces the superconducting magnet and the ac system, controlling the active and reactive power flow. Due to high-frequency switching of the PCS, the voltage distribution on the HTS magnet will affect the magnet insulation and quench detection. Considering the interaction between the PCS and the magnet, the output characteristics of the voltage-source-type and current-source-type PCSs are analyzed. Subsequently, the transient model of magnet is deduced to analyze the voltage distribution on the HTS magnet. The voltage distribution on an HTS magnet model is analyzed with the proposed method, which is later utilized to evaluate its insulation design.
