Transient temperature analysis and short-term ampacity calculation of power cables in tunnel using SUPG finite element method
In this paper, transient temperature distribution and short-term ampacity of underground power cables that were placed in tunnel were calculated. Using finite difference method (FDM), transient temperature calculation process of underground cables in tunnel was divided into discrete groups of transient time step. A Streamline-upwind/Petrov-Galerkin (SUPG) stabilized finite element method was used to solve the air governing formulations and each time step-temperature distribution of underground cables in tunnel. The transient temperature distribution of underground cables in ducts was calculated. Short-term ampacity of underground cables was calculated by Newton-Rahpson iteration method.
