摘要：

The paper presents a novel method of calculating AC loss in solenoidal high temperature superconducting windings of the transformer type. Losses caused by the external magnetic field and due to transport current are modelled together and account is taken of highly non linear characteristics of the material. In tape conductors the loss due to the parallel field component is usually small whereas the effect of the normal field component is significant. A non linear 2D finite difference formulation is derived for the superconductor and linked with a linear finite element model representing the rest of the transformer and the interaction between coils.
