中文摘要 | 目前臺灣鐵路管理局正進行西部幹線北部區段基隆至新竹間「臺鐵捷運化」規劃建造,其電力供應係由臺電69kV 輸電系統供電,經主變壓器以Le Blanc 接法將三相69kV 轉換成25kV 兩單相(M 相及T 相)電壓,分別引至電車線以供電力機車及電聯車所需之動力;而臺鐵列車為一種動態性的牽引動力負載(電力機車、電聯車),針對其運轉特性加以探討,由於電化鐵路系統的耗電量與尖離峰載運量及列車班距有密切的關係,系統是否正常運轉關係著旅客的時間與安全,因此供電系統應相當嚴謹之規劃設計要求。 |
英文摘要 | At present the TRA is carrying out engineering work for a plan to turn the Keelung-Xinzhu section of the western trunk line into an urban rapid transit system. Power is supplied by a Taipower 69 kV transmission system and, using the Le Blanc connecting method, the main transformer converts the three phase 69V to two single phase 25 kV (M phase and T phase) voltage, which powers electric locomotive and EMU respectively. This power conversion gives TRA trains a kind of dynamic (electric locomotive and EMU ) traction load operating property. Electrified rail system power consumption is closely connected to peak and off-peak passenger volume and train headway and the normal operation of the system has a direct influence on passenger traveling time and safety, therefore the requirements of power supply systems are very strict. |
