摘要

未來大量分散式電源及電動車的加入，將對配電系統的控制造成極大的衝擊，目前台電公司及絕大多數國家所使用的配電自動化系統仍屬於中央集中控制方式，不利於對分散式電源及負載的控制，難以達成提供客戶主動參與機制、容納所有可能的發電與儲能方式及對於系統擾動的自癒能力等智慧配電的目標。
對於智慧配電必須面對故障所造成的雙向電力潮流、配電饋線資訊末端設備(Feeder Terminal Unit, FTU)需具備自主判斷能力及全自動化的故障偵測、隔離及復電(Fault Detection, Isolation, and Recovery, FDIR)功能，本論文針對架空與地下線路之不同故障位置進行討論，提出可用於未來配電系統上之故障偵測演算法。由於目前台電的配電系統架構與未來理想化的系統架構尚有一段距離，因此，本文也規劃出可應用於台電公司配電系統現況之判斷邏輯，並以智慧型電子裝置(Intelligent Electronic Device, IED)進行硬體模擬加以實現。
本論文所提出之判斷邏輯經IED硬體模擬測試成功，具備達成智慧配電的技術雛型，未來可以此為基礎，發展更完善的智慧配電控制技術。

The connection of distribution energy resources and electric vehicles will impact the operation of power distribution system in the future. The centralized control system used by Taiwan Power Company (Taipower) and power companies of most countries all over the world is not fitting the requirement for the control of distribution energy resources and loads. Therefore, the goal of smart power distribution system such as active custom participation, the permission of all possible generation and energy storage connection and self-healing is hard to reach.
The smart power distribution system has to solve the bilateral power flow problem, to meet the requirement of self-determination ability of Feeder Terminal Unit (FTU) and to establish fully automated Fault Detection, Isolation, and Recovery (FDIR) functionality. This thesis discusses the fault occurred in different areas of overhead or underground feeders and proposes the fault detection algorithm for FTU that can be used in the future. Because there is still a gap between the ideal power system and the system being used in Taiwan Power Company, an algorithm that fit to the configuration of current Taipower’s distribution system and a hardware simulation using Intelligent Electronic Devices (IEDs) are also be developed and implemented in this research.
The algorithm proposed in this research has been tested by IEDs successfully. It is a prototype to approach smart power distribution technology which can be developed in the future base on this algorithm.
