因應石油銳減所引發的節能概念,智慧電網已受到廣大的注意。本論文所研究之內容為實現可靠性的智慧電網中實體層之間的信號傳遞機制。尤其採用NB-PLC標準中之G3-PLC,亦是此研究之重點。訊號產生與回復部分使用兩臺德州儀器公司所製造之數位訊號處理器(DSPs),透過使用TI 6416開發板模組所形成之數據機,以及採用G3-PLC標準,使本研究可以更加適切地選擇取樣頻率;另外,為訊號傳送與擷取使用多速率信號的處理架構,可解決DSP所帶來的限制。進一步地,為有效率的解決因NB-PLC脈衝雜訊所引起的效能低落問題,事先發展之演算法亦在實作中使用,並測試其在真實環境下的發展可能性。此外,為促進電力線上的訊號傳輸,在實驗中建置兩個自行設計之耦合器,並依照G3-PLC裡的規範操作頻率範圍進行測試。模擬及實作結果皆在本研究中揭示,以用來證明所提出的G3-PLC測試平台。
Smart Grid has attracted considerable attention largely thanks to the essence of energy saving to counter a rapid decline of fossil fuel resources. Narrowband power line communications (NB-PLC), an enabler for quality-assured signaling delivery among entities within Smart Grid, is studied in this thesis. In particular, the implementation of a popularly adopted NB-PLC standard, namely G3-PLC, is the primary focus of this study. Two Texas Instruments’ Digital Signal Processors (DSPs) are used for signal generation and recovery; with TI 6416 development kits serving as a modem, an adaption to the G3-PLC standard prompts this study to properly select the sampling rate accordingly; and implementing a multi-rate processing framework for signal transmission and acquisition efficiently meets the limitations imposed by the DSP. Furthermore, a previously developed algorithm to effectively overcome the performance degradation caused by strong impulse noise in NB-PLC is implemented to demonstrate its feasibility in the real world. Besides, to facilitate signal delivery on power lines, two self-designed couplers are built and subsequently tested in compliance with the operating frequency range specified in the G3-PLC. Both simulation and experimental results are carried out in this study to justify the proposed implementation platform for the G3-PLC.
