工業配電系統整合分析程式視窗化之研發
與Ethernet-RS485雙向介面轉換器

本論文旨在研發一套適合工業配電系統的整合分析程式與數據監控系統，以提昇規劃、操作與管理之效能以及協調機制。應用程式係以匯流排阻抗矩陣為基礎，將傳統的電力潮流分析、功率因數改善、大馬力馬達起動特性模擬與短路故障容量計算等單一功能的各個分析程式整合成具有多功能之單一應用程式，而且整個操控作業皆在友善的人機介面環境下進行，其中元件資料視窗與圖控視窗兩個為主要的視窗。所有數值運算結果採用一致的圖資格式，呈現在對應的作業視窗當中，以提供使用者即時對系統作觀察或修改之用。另外，為了達成理論設計能趨近符合現場實務，本論文利用Ethernet的高擴充性和RS485的長距離傳輸優點，研發Ethernet-RS485雙向介面轉換器，構成星狀拓樸網路介面，將使得工業配電系統執行更準確、更快速與高效能的監控。

This thesis presents an integrated analysis program and supervisory control using Ethernet-RS485 bidirectional interfaces for industrial power distribution systems, which improves efficiency and coordinating mechanism among planning, manipulation and management. Based on the Bus Impedance Matrix building algorithm, the proposed software program organizes power flow analysis, short circuit capacity calculation, simulation of large motor starting characteristics, and power factor correction into a multi-function integrated program, which is superior to several mono-function conventional programs. All functions are operated in a user-friendly man-machine interface environment which includes two major visual windows of element-data and icon-control. Numerical analyses in the default graph-text format are displayed on the output windows such that the user can observe or revise the system real time. In addition, in order to implement a theoretical case, this dissertation combines the high expanding advantage of Ethernet with the long-range transmitting characteristic of RS485 to perform a data-collecting integrated circuit, Ethernet-RS485. In industrial power distribution systems the integrated circuit with a star-type topological structure is used to execute supervisory control accurately, speedily and effectively.
