Effects of bias power supply on bridge type superconducting FCL

摘要

The effects of bias power supply (BPS) on bridge type of SFCL are studied in this paper. The main research method is a superconducting reactor charging analysis. With shift of charging path and change of charging power source in a process of short fault, on the condition of the SFCL with BPS in two connection modes, load current distortion is eliminated and the SFCL limiting capability is enhanced, And the parameters of the BPS is also optimized. Simulation and experimental results validate the necessary of the BPS to enhance the limiting capability of the SFCL.
