先進讀表基礎設施(Advanced Metering Infrastructure, AMI)於智慧電網中扮演不可或缺的一部分，其中資料收集器(Data Concentrator Unit, DCU)為AMI主要設備之一，DCU負責收集各數位電表之資料，並將所儲存之資料定期地回傳至電表資訊管理系統(Meter Database Management System, MDMS)。如DCU可提供更彈性之雙向且即時通訊功能及分散式運算功能，將可提供有效率之能源控管，因此本論文著重於DCU之加值功能的設計與開發。本論文主要設計及開發可用於AMI且具IEC 61850通訊協定及竊電偵測系統等加值服務AMI之DCU，具可針對各用戶進行用電資訊收集並透過竊電機率指標之分析來判斷各用戶是否有竊電之嫌疑。除了開發DCU之加值功能外，本論文亦設計一視窗化界面之遠端電力監控系統，透過製造訊息規範(Manufacturing Message Specification, MMS)與資料收集器進行電力資訊監測。本論文透過所規劃之系統架構，進行DCU加值功能開發，然後實際與商用設備及軟體進行IEC 61850通訊協定驗證，及竊電機率指標之可行性探討。

Advanced Metering Infrastructure (AMI) plays an important role in smart grids. Data Concentrator Unit (DCU), used to collect data from smart meter of customers and transmit them to Meter Database Management System (MDMS) regularly, is the core component in AMI. If DCU can provide more advanced two-way communication and distributed computing, more efficient energy management can be achieved. Therefore, this thesis focuses on designing and developing value-added functionalities for DCU. The value-added functionalities designed in this thesis include IEC 61850 communication protocol and electricity theft detection system. The proposed electricity theft detection system utilizes the collected customer power consumption data to calculate the electricity theft probability index. The possible electricity thefts can then be found out. A windows-based Human-Machine Interface (HMI) for remote electricity supervisory system using Manufacturing Message Specification (MMS) is also implemented. The windows-based HMI is used to acquire and monitor the collected data in the proposed value-added functionalities of DCU. An experimental DCU platform is designed to realize the proposed value-added functionalities and to simulate the feasibility of the electricity theft probability index. Besides a commercialized software is used to verify the consistency of IEC 61850 communication protocol implemented in the proposed DCU.
