中文摘要 | 因高速鐵路的單相牽引負載會造成其電力供應系統的電壓、電流不平 衡。其不平衡之程度主要受高速鐵路供電方式的影響,即受高速鐵路各變電站變 壓器的種類及接法的影響。而系統電壓及電流的不平衡則會增加額外的系統損 失、擴大通訊干擾、造成電動機過熱等不良現象,因而導致各項電力設備如變壓 器、傳輸線、電動機等需做適度的減額運轉策略,而相關保護設備可能因而發生 誤動作現象,嚴重影響其電力供應系統的供電安全與品質,故需做深入而廣泛的 研究以資謀求對策、減輕影響。本論文即針對高速鐵路負載對其電力供應系統之 不平衡影響進行研究,分析高速鐵路的列車負載特性乃為本研究的首要工作,並 進行推導其變電站與變壓器數學模型,利用推導所得的數學模型配合三相電力潮 流分析程式,高速鐵路負載對電力系統的影響評估工作,即得以更嚴謹的方式進 行,而未來系統電壓不平衡之防範與改善措施,亦得以具體地提出與執行。 |
英文摘要 | Single phase demand of high-speed railway may causeconsiderable voltage and current unbalances on its power-supply system. Rigorous evaluation of their effects is thereforehighly important. The methodologies for estimating the degreeof voltage and current unbalances and their effects have beendeveloped and introduced in this paper. Simple formulas thatare usually used by the related engineers and consulters toevaluate the voltage unbalance were derived first. Furthermore, a three-phase power flow program was developedfor detailed study. However, the features of traction loads arerequired to satisfy the requirements of the rigorous analysis.Therefore, simulation of dynamic traction loads was done toobtain the load patterns of power - supply substations along arailway. On the basis of the proposed methodologies andresults, related improvement projects can be judged andconducted to reduce the voltage and current unbalances andconsequently minimum their effects. |
