配電系統為電力網之下游，肩負提供用戶可靠及高品質電力之重要環節。因分布面積廣，開關數及變壓器等設備數量眾多，除須有計畫性的進行維護，避免停電事故外，當線路發生故障時，如何迅速發現故障點，並予於隔離及修復，加速回復供電，以減少對用戶之影響，必須經由自動化系統加以達成。目前普遍裝設於配電線路之開關，均採用傳統人工調度操作摸式，每當線路發生事故時，需耗費較多時間，始能恢復供電。為因應時代需求及符合高供電可靠度政策，結合電腦、通訊、控制等尖端科技與配電系統整合，建置一套符合現今運轉調度需求之「配電饋線自動化系統」，以提升服務用戶之品質及內容，相關資訊技術如GIS（地理資訊系統）、Real Time Database System（即時資料庫系統）、Relational Database System(關聯式資料庫系統)及較佳通訊協定等之引入，可達到饋線監視、控制、遙測及故障偵測隔離及復電等自動化系統功能。
本論文針對配電饋線自動化系統，以C/C++為設計平台，並且與Microsoft Access 及Oracle資料庫做連結，開發FDIR軟體。本套應用軟體搭配GIS，經由網路拓樸分析(Topology Processor)，建置饋線開關的上下游及其連結關係，並可利用即時資料庫系統所傳回的即時三相電流值及過電流旗號，立即判斷故障點區段，以

The distribution system is the downstream of a power system, which is used to provide high reliability and quality electricity service for customers. Because of the wide area with voluminous facilities, involves in a distribution system, the preventive maintenance of distribution system components is important for the distribution system. For a fault contingency, the utility company has to identify the fault location to isolate the fault and to restore the electricity service for the un-faulted but outage area as soon as possible to enhance the service reliability. With the advancement of compute technology, the distribution automatic system (DAS) has been applied to solve the fault contingency problem by integrating the geographic information system (GIS) real time database (RTDB) relational database with master station and communication systems for the monitor and control of distribution systems.
To achieve the function of fault detection, isolation and restoration (FDIR) of distribution automatic system, the FDIR software has been developed with C++ platform. By retrieving the distribution system components in GIS, the Topology processor is applied to identify the connectivity of distribution network. When a fault occurs, the fault flags will be generated and retrieved from the field feeder terminal unit (FTU) according to the states of fault flag and network configuration, therefore the fault location is identified very quickly. After isolate the faulted section, the feeder circuit breaker is closed to restore the upstream service. Based on the loading levels of supporting feeders, the downstream restoration is therefore obtained by closing the normal open switch, besides the application software can also be used to derive the optimal switching operation for loading balance of distribution feeders to enhance the operation efficiency of distribution systems.
