電力線通訊應用於台電饋線自動化
Application of Power Line Communication for TPC Feeder Automation
摘要
通訊在饋線自動化系統中擔任重要的角色，平日除收集電壓及電流等資訊傳回控制中心外，於事故發生時，可供隔離事故區段與恢復供電，有效縮減停電時間及範圍。目前台電公司饋線自動化正積極進行當中，這些饋線自動化工程進行中也鋪設光纖作為通訊，然僅限於主饋線，連接用戶之分歧線則尚未進行自動化，也就是無通訊網路。為了未來用戶服務自動化與饋線設備監測自動化，運用電力線通訊技術來達到上述目標為可行方案之一。基於此，本論文將就電力線通訊技術加以探討與評估在配電饋線之各種應用，以期能夠建立方便、價格低廉與穩定性高的網路系統，充分發揮電力線的附加價值，進而達到用戶服務自動化與饋線設備監測自動化之目標。本研究建置一個中壓PLC與光纖網路連接的通訊系統，其PLC的傳輸速率可達100Mbps以上，研究結果顯示電力線載波技術可用來傳送語音、數據及影像等訊號，足以應用於饋線自動化的各種應用。

Communication play an essential role in the TPC Feeder Automation System.In normal operation,the voltage and current information should be collected and sent to the control center.When a fault occurs,the switches provide the fault isolation and service restoration functions commanded from the control center,which can effectively reduce the outage time and range. This thesis presents the technology of power line communication (PLC) and establishment of PLC trial site in feeder automation. By integrating PLC Network, this system has shown to provide a lot of the benefits, including reduced commissioning time and cost, simplified system integration, increased system up time as well as the path for system growth. In this thesis, the tendency of PLC development, the commercial system in the worldwide and the performance of trial site in taipower also have been described.This thesis built a communication system using MV PLC to connect Optical Fiber Communication Network.The PLC transmission rate is more than 100Mbps. The experiments show that power line carrier is suit for audio, data and vedio transmission.It is enough for all applications of Feeder Automation System.
