鐵路交通運輸為我國重要的基礎交通建設，因此如何提昇電化鐵路系統供電的電力品質與可靠度，以維護運輸的品質與現場操作人員的生命安全，乃是一項重要的工作。近年來台鐵為了提高供電設備容量與增加運轉效率新購了大量採用閘流體控制技術的電力電子之列車，造成台鐵系統的非線性負載增加並使得諧波電流含量增加，進而影響同一饋線上其它用戶的用電品質，因此有必要建立一個含列車動態行為的台鐵供電系統的電網路模型，用以分析各設備之諧波含量。
本文首先以電磁暫態模擬程式(EMTP)建立含列車負載的台鐵供電系統的電網路模型，模型中使用EMTP中之控制系統暫態分析(TACS)來撰寫邏輯控制時序指令模組，用以模擬AC/DC整流器與DC/AC換流器的導通時序，同時亦結合馬達模組，即可完整的模擬台鐵系統在列車負載不平衡及平衡下的諧波電流情形，期能以模擬結果作為台鐵工程人員判斷事故及評估諧波影響時的依據，並可避免實際量測時的危險性，更可減少因事故造成的人員傷害與設備的損壞等考量。
另一方面，本文不僅針對列車滑行時諧波電流的分佈情形作探討，更藉由完整的台鐵EMTP電網路模型來分析列車含動態(暫態)行為時，Le Blanc變壓器與Zig-Zag變壓器的諧波電流含量。以提供台鐵在分析諧波與設定保護協調時的參考依據。

Since railway is a fundamental construction of transportation, how to enhance the power quality and reliability of railway system in order to maintain the quality of transportation service and to secure the safety of operating personnel is a very important task. Engineers of the Taiwan Railway Administration (TRA) purchases a large number of trolleys of power electronics which were implemented into the thyristors controlled technology to raising the capacities of power supply and increasing operating efficiency recently, it would increase the load of TRA to be nonlinear, the contents of harmonic current, and also influence the other user in quality of power utility on this bus. Therefore, it is necessary to establish a complete power supply model of TRA system that including dynamic behavior of trolley, so as to analyze the content of harmonics in each of equipment.
First, the Electromagnetic Transient Program (EMTP) can be applied to build up a model of TRA system that includes the load of trolleys. In the model, Transient Analysis of Control Systems (TACS) can be used that was involving in EMTP to compose the module of logic controlling commands, so as to simulate the conducting procedures of AC/DC converter and DC/AC inverter, at the same time, to combine the module of motors. Finally, we can simulate the harmonic currents upon the condition of unbalanced and balanced load of trolleys in TRA system. We expect these results could be a plus when the engineers ascertain the fault and judge the influences of harmonic. Thus, we can keep away from the danger in actual test, even more, we can reduce the hurts of operating personnel and the damages of equipment.
Besides, the essay not only aimed at the distribution of harmonic currents when trolleys sliding but also analyze the contents of harmonic current in the Le Blanc transformer and the Zig-Zag transformer when trolleys include dynamic behavior by the complete EMTP model of TRA power supply system. We hope to provide the references and bases when engineers of TRA analyzing the harmonic contents and setting protective coordination.
