碩士 === 國立中山大學 === 電機工程學系研究所 === 89 === Nowadays, the economic grows fast and changes a lot. Meanwhile, the central city gets bigger and bigger. More and more buildings locate everywhere while people enjoy their modern life. The needs of electricity grow by the way. In order to provide more power, the Power Company has tried very hard to find new resources. However, there is another problem when transferring the power through crowded city. To avoid the geographic limitation, most of the overhead lines have been changed into under ground lines instead. Sooner or later, the under ground cable will become the main power transmission. This thesis focuses on the current rating distribution of Taiwan 161KV line with various PE underground cables that contain one circuit, two circuits, four circuits, and eight circuits. The current rating goes within various pipes. To find the best economic benefit with the lowest investment by rearranging the pipes to reach the most current rating and by matching the current rating from under ground cable with the over head cable is the main goal of this thesis. JCS NO.168 analyzes the set up map for all the pipes. In order to offer the best power supply, to maintain the longest cable life within the acceptable working days, the calculating scripts support to figure out the current rating in shortest time.
