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

摘要： PROBLEM TO BE SOLVED: To provide a system capable of estimating the change of a cable conductor temperature by a finite element method, in consideration of an effect by a cooling water channel when the cooling water channel is provided in parallel with a power cable buried underground. SOLUTION: In this cable conductor temperature estimation method, a plurality of analysis faces crossing the cable buried underground and the cooling water channel are set, and while performing transfer treatment of a cooling water temperature from the upstream side to the downstream side of the cooling water channel between the analysis faces, temperature analysis is performed in each fixed period by applying the finite element method based on a heat conduction equation to the analysis faces, and thereby the change of the cable conductor temperature is simulated by reflecting the state where the cooling water absorbs ambient heat from a prescribed temperature at the supply time and simultaneously cools the cable.

摘要： PROBLEM TO BE SOLVED: To estimate change in the conductor temperature of a power cable buried underground with accuracy by a finite element method. SOLUTION: A system is constituted so that a predetermined area, including a surface and a buried cable, is divided into finite elements. Then, the finite element method is applied to the divided models, and thereby the temperature of each part in the above area, including conductor temperature, is computed from moment to moment for a predetermined period of time. The heat balance on the earth surface is computed, using meteorological data for the area as the object of estimation, so that changes in the cable conductor temperature are estimated with accuracy.
