摘要

台灣位處於亞熱帶區，四面環海隸屬於海島型氣候，氣候變化非常頻繁，尤以夏季特別容易發生雷擊，隨著雷擊的發生，將對輸電線路與設備造成損害及影響。台南科學園區鄰近輸電線路多行經山區，屬於高落雷區，可能因雷擊對南科園區供電品質造成影響。
本論文首先介紹雷的產生與雷擊突波特性，接著利用台電鐵塔定位坐標、歷年落雷資料，分析南科鄰近各輸電線路之雷擊機率分布；利用Matlab-Simulink軟體分析南科鄰近各輸電線路可靠度與供電系統可靠度，並比較與備用供電系統可靠度之差異，以作為提高供電系統可靠度之參考。

Being located at the subtropical area and surrounded by sea, the lightning stroke events happen frequently during the summer season in Taiwan. Lightning strokes usually cause the short circuit fault which results in the outage or voltage sag in the power system. Because the power transmission lines which serve Tainan Science-Based Park pass through the area of serious lightning strokes, the power quality and reliability will be affected by the lightning strokes.

In this thesis, the phenomenon and characteristics of lightning surges are introduced first. Then the probability of lightning of nearby transmission lines is analyzed statistically from the historical recorded data. Based on the statistical results obtained, the ‘Matlab-Simulink’ software package was adopted to simulate the reliability of power system. The backup transmission line was also taken into consideration in the simulations.
