中文摘要 |
本論文係探討低頻率輸電線路所產生之磁場,其計算分析方法與抑低對策。先以台灣本島運轉中之三相交流輸電線為架構,運用近場效應、畢奧沙瓦特定律及雙複變數理論,推導計算導線在特定傳輸架構下之分佈磁場;其次利用磁場向量分析與Matlab程式模擬,探討各種磁場抑低方式和特點;最後採導線「回路空間佈設」及「時間相位安排」等兩種磁場抵消技巧為研究主軸,瞭解其應用於不同輸電線路架構,各種組合下之磁場效應。由研究結果發現,對於導線的空間及相位配置,作適當安排,確實能將輸電線路產生的磁場抑低。因此於設計建置輸電線路前,利用此技巧妥善規劃,不僅耗費成本最低,且能達成降低磁場的成效。 |
Abstract |
This thesis presents a computational analysis of the magnetic field of low-frequency power transmission lines, and the approaches to its suppression. First, according to the structure of Taiwan's three-phase A.C. transmission network, this research calculated the distribution of conducting wires' magnetic field under specific configuration by applying the theories of Near-field effect, Biot Savart's law, and double complex number. Second, this research explored the features of various approaches to magnetic field suppression with magnetic-field vector analyses and Matlab simulations. Finally, two magnetic-field cancellation methods, the “circuit space arrangement” and “time phase permutations” were adopted to investigate their magnetic effects under various structures and combinations of transmission lines. This study reveals that the magnetic field can be effectively suppressed by using appropriate configuration of transmission lines in space and phase. By applying the result to the design and construction of transmission lines, we can meet not only the requirements of magnetic field reduction, but also the needs of the least cost. |
