要約(英語): Recently, a more highly accurate transmission capacity calculation program is needed in considering the increase of current value and avoidance of a heavy load in summer to operate the existing power equipment efficiently. Therefore, Tokyo Electric Power Company and JSOL Corporation jointly developed the highly accurate transmission capacity calculation program that a transient analysis by two-dimension finite element method is possible. In general, the air around the underground transmission cable influences the conductor temperature of the cable by the thermal resistance of the air. If this thermal resistance is greatly estimated, the temperature of the cable is calculated highly, and might become the result of far apart from actual temperature distribution.In this report, we newly evaluated the influence of convection and heat radiation upon the thermal resistance of the air in a duct and trough by the thermal fluid analysis in detail, and applied the examination result to the highly accurate transmission capacity calculation program. In addition, we also report that the tunnel model which can take into consideration compulsory cooling equipment such as cooling pipes and ventilators in a tunnel was established.
