摘要： PROBLEM TO BE SOLVED: To provide a system which can estimate a change in the conductor temperature of a power cable laid in an underground cable tunnel by considering the movement of air in the cable tunnel. SOLUTION: A plurality of analysis planes A to D crossing the cable tunnel 1 in which a cable 4 is laid are set. While performing processing for delivering air temperature from the upstream side to the downstream side between the analysis planes A to D accompanied by the movement of the air in the cable tunnel, the finite element method on the basis of heat conduction equations is applied to the analysis planes A to D to perform temperature analysis. A change in the cable conductor temperature is thereby simulated by taking into account a cooling effect through the movement of the air in the cable tunnel. COPYRIGHT: (C)2006,JPO&NCIPI
