摘要: 本論文針對配電饋線上的電壓與電流做探討,設計適用於在饋線上做檢測的電路。電力系統中,包含發電、輸電與配電系統,其中配電系統的涵蓋範圍與用戶數量最多,對電力公司而言在線路維護,與故障點探查上,均相當的不便利。為了提高供電品質,台灣電力公司致力於電力自動化的推廣,而配電饋線自動化系統則為其ㄧ員,配電饋線自動化系統成為管理者的眼與手的延伸,遠距離的針對配電饋線網上的每一個節點作監控。在毎ㄧ個節點上安裝一饋線終端單元(Feeder Terminal Unit, FTU)作為監控的工具,FTU負責檢測饋線上的訊號,當有異常狀態出現時快速的通知管理者,以做開關的投入切開控制,為用戶提供更高的供電可靠性。本文電路的設計目標為設計一個適用於FTU之上的訊號檢測電路以期符合台電所需的數位與類比輸出入接點規格。
In this thesis, we study the signal at the power feeder and design a suitable detection circuit for the voltage and the current of the power feeder. A power system is known to be composed of generation system, transmission system and distribution system. There are many users and large working area in distribution system. If there are some faults occur, it cost a lot for Power Company to keep the system working. Automatic feeder control system supplies that information in each node of distribution system. Each node has a Feeder terminal Unit that detects the current and the voltage in feeder, and control the circuit breaker with the maintenance man of Taiwan Power Company. Taiwan Power Company can supply better service reliability with using FTU. The goal in this thesis is to design a detection circuit, the input and output in a FTU with the specifications of Taiwan Power Company.
