Two Dimensional Finite-Element Simulation of a High Temperature Superconducting Synchronous Generator During Three-Phase Short-Circuit Fault Condition Using Full Transient Non-Linear Rotating Machine Model

摘要

This paper describes fault analysis of a 100kVA high temperature superconducting synchronous generator (HTSSG) using two dimensional (2-D) finite element modelling. The 100 kVA generator dimensions are based on the actual machine under construction in the Electrical Power Engineering Research Group at University of Southampton, United Kingdom. The non-linear transient modelling was simulated taking into account the relative movement between the stator and rotor. The high temperature superconducting field windings were analysed using external circuit equations as the equivalent supply voltage and resistance.
