- 中文摘要: 本篇論文主要在推導高速鐵路變電站所常採用之勒布朗變壓器的精確數學模型;並應用所推導出之模型分析高速鐵路負載對其電力供應系統的電壓不平衡影響;進而與高速鐵路變電站所常用之其他變壓器連接方式比較以評其優劣。勒布朗變壓器的一次側可以採用△型或Y型連接,二種連接方式略有不同,但其等效電路模型在本論文中都已被成功的推導出來,並建立在實際之相座標系統中,能忠實的展現出該變壓器原有的特性。所得結果對研究高速鐵路是否能正常運轉及其負載對電力系統的影響評估工作都頗有助益。
- 英文摘要: This paper introduces the detailed network models of Le Blanc transformers with star- and delta-connections on the primary windings in phase co-ordinates. The Le Blanc transformer is one of thetransformers which are commonly used in power-supply systems of high-speed railways. Because largehigh-speed railway demands are usually single phase and are directly fed from a public power system,the effects of the former on the latter are significant. Detailed models of traction substation transformersare, therefore, required to evaluate these kinds of effects.Furthermore, these models are necessary tostudy the performance of power-supply systems of high-speed railways to make sure that railway systemscan be operated normally even when one of the traction substations is outage. Detailed models of otherconnections, such as single-phase, V and Scott, have been developed by the authors of this paper. Thesepreviously developed models will be used here to compare their characteristics with those of the LeBlanc connection. The advantages and disadvantages of the Le Blanc connection are also briefly describedhere.
