發展一個使用ZigBee技術具有直接負載控制能力之電力監測系統
摘要
本文利用ZigBee、DSP與網路服務(Web Services)技術，發展一個能夠即時偵測與處理電力異常，並執行相對直接負載控制之新式電力監測系統。具體地，我們設計一個以DSP為運算核心與ZigBee無線傳輸的電力監控模組，使本系統具備了計算電力參數、偵測電力品質異常、電力資訊傳遞與直接負載控制的功能。同時，我們運用網路服務技術來建構系統的通訊基礎建設，使用者可於任何時間、任何地點、使用任何可上網的裝置來操作本電能管理系統的各項功能。最後，我們將所研發之系統實際應用於校園的用電監測，整合測試結果顯示本系統確能符合設計目標，並表現良好性能。本研究首次結合ZigBee、DSP與網路服務技術來開發電力監測系統，研究成果具創新性與實用性，將可做為未來發展電力監測系統的有用參考。

This paper utilizes Zigbee, DSP and Web Services technologies to develop a novel power monitoring system (PMS) which is capable of detecting and handling power exceptions in real time and performing associated direct load control. Specifically, we design a portable power monitoring module that utilizes ZigBee for wireless communication and DSP (Digital Signal Processing) for rapidly computing power parameters and detecting power quality anomalies. Also, the Web Services technology is used to construct the communication infrastructure of the system. Hence, users can easily access and use the powering-monitoring related functions through networks. Finally, we construct a paradigm system for monitoring campus power consumptions to evaluate and validate the effectiveness of the proposed PMS. The testing results show that the functions of the proposed PMS can comply with the designed objectives. The paradigm PMS also demonstrates that good performances in direct load control and warning message transmission: the average time of from detecting a power abnormal event to completing direct load control is about 62 ms, and the average time of from sending the warning message by the server to receiving the message by the person in charge is about 10 s. This work possesses novelty for first time integrating ZigBee, DSP, and Web Services technologies to develop PMS, and can be a useful reference for future developments of PMS.
