摘要:變壓器是電力系統中的核心設備之一,在實際應用過程中,由于變壓器故障的出現,會嚴重影響運行安全,因而對其故障進行自動化監測具有重要意義。本文提出了一種基于ZigBee無線傳感網的變壓器在線監測系統架構,設計了監控數據轉發和基于MATLAB的數據匯總平臺,可以完成對變壓器繞組溫度、局部放電、氣體濃度等故障表征參量的監控,該系統具有價格低、易于實現、可靠性高等特點,有一定的實用參考價值。
關鍵詞:電網變壓器;狀態監控;遠程監控
Abstract: Transformer is one of the key equipment in the power system.In practical application, the transformer fault seriously affect the operation safety, so it is of great significance to carry out automatic fault monitoring. In this paper, an on-line monitoring system architecture of transformer based on ZigBee wireless sensor network is proposed.Based on the ZigBee wireless sensor network, the platform of monitoring data transmission and data collection based on MATLAB is designed.It can be used to realize the monitoring of fault characterization parameters such as transformer winding temperature, partial discharge,gas concentration, etc. The system has the characteristics of low price,
easy implementation, and high reliability, and has certain practical value.
Key words: Power Grid transformer; Condition monitoring; Remote monitoring
