Development of a High Temperature Superconducting Controllable Reactor Based on Finite Element Method

A new 40kVA, 400V high-temperature superconducting (HTS) controllable reactor of transformer type has been designed, built and tested. The reactor has totally 3 windings and utilize Bi2223 HTS materials to wound the inside two windings which are responsible for the adjust of the reactor's reactance. A finite element model was developed and simulation was conducted to predict its performance, such as capacity, harmonic and response. Then experiments were carried out and results are compared.
