主　　题：Finite difference time domain method 

摘      要：In this paper, detailed mathematical formulation of a coupled electro-thermal model for transient studies of high-temperature superconducting (HTS) transmission systems is presented. Regarding the thermal modeling, the volume-element method is used in order heat transfer equations on a two-dimensional axisymmetric cable model to be solved and temperature distribution over space and time to be determined. For the modeling of the electric part, a constant-parameter finite-difference time-domain method is utilized to calculate voltages and currents over space and time as well. The analysis is conducted on a bipolar cable suggested by the Electric Power Research Institute for long-distance HTS dc transmission to highlight the electric and thermal domain interaction under transient conditions. Different test cases are conducted to evaluate the electric and thermal transient performance of the examined HTS cable. © 2002-2011 IEEE.
