Abstract
A method based on the time domain response and superposition property of heat conduction is studied to realize the fast calculation of transient temperature rise of soil directly buried cable group.Transient temperature rise of cables could be simulated as the superposition of several single-core cables.The self-heating of single-core cable is described by using the self-excited response model.The interaction of different single-core cables is described by the dynamic response model.Besides,the integrated temperature rise of cable core is obtained by node coupling method.In the case study,model parameters are firstly extracted by Cymcap.Temperature rise under typical operating conditions is then obtained respectively by the lumped parameter model and commercial software.The comparative results verify the validity of the method proposed in this paper.关键词
