• 中文摘要： 在變電站與各饋線間的雙相通訊中，配電線載波(Distribution Line Carrier, DLC)是一種良好的介質。在以前許多有關配電線載波傳輸測量的報告中指出，由於配電系統的複雜性，以致於很難去預測配電線上的訊號傳輸；故需要有分析的工具，來分析配電線上的訊號傳輸，幫助有關配電自動化的通訊設計研究。在本論文中，以三相導納矩陣、稀疏矩陣及稀疏向量技巧為基礎，提出一更有效的方法，可針對任何饋線點的電流輸入，來計算任何饋線點的電壓輸出訊號。稀疏矩陣及稀疏向量技巧可以減少執行時問與所需記憶體空間，而用補償技巧來考慮網路參數的改變對訊號傳輸的影響。
• 英文摘要： A distribution line carrier is one of the media alternatives available for providing two-way com-munications between a substation and various feeder locations. Distribution line carrier propagationmeasurements reported in the previous literature have shown that propagation of signals on a powerdistribution line is difficult to predict due to the complexity of distribution systems Analytical toolsthat could analyze signal propagation on distribution lines would facilitate the study of this communicationscheme for distribution automation. In this paper, an efficient approach based on a three-phase busadmittance matrix and sparse matrix and vector techniques is proposed to calculate the received signalvoltage at any feeder point of interest for the transmitted current at any feeder point. Sparsity techniquesused to reduce execution time and memory space requirements and compensation techniques used to takeinto account the effects of network parameter changes on signal propagation are described.
