[[alternative]]Development of Operation Aid Information System for Hydro Power Plants

碩士電機工程學系[[abstract]]本論文利用分散式資料收集模組及資料伺服機，即時收集、監測及儲存明潭電廠機組之運轉資訊；藉由與明潭電廠區域網路之整合，開發適合明潭電廠需求之「水力電廠運轉輔助資訊系統」，供明潭電廠控制室以外之區域網路各用戶，於辦公室即可查閱即時的運轉資訊或歷史紀錄，以取代傳統機組運轉趨向記錄器並加強設備監測之功能。透過機組推力軸承溫度及主變壓器電流變化之即時監測及記錄功能，可使電廠值班人員讀取更具準確性及可靠度之機組運轉溫度及主變壓器電流資料，提升機組運轉安全；機組發生事故時亦可協助機組事故原因之判斷及探討。藉由水力電廠運轉輔助資訊系統之開發，以改進並解決明潭電廠機組監視控制及資料收集系統所面臨之缺失及問題。[[abstract]]Abstract Connecting with the local area network of Mingtan Power Station (MPS), this thesis utilizes distribution data acquisition module and data server for real time data acquisition and monitoring of MPS’s unit operation to develop an operation aid information system for hydro power plants. Instead of traditional trend recorder and increment the function of device supervisor, the system provides local area network users to browse the operation information and history data at their own office. Through the monitoring and recording function for instant temperature of unit’s thrust bearing and current of main transformer, more precise and reliable data can be read by operators of MPS and workforce safety is therefore increased. The data also can help investigate accidents of MPS’s machine operation. Therefore, the development of operation aid information system for hydro power plants can solve the problem and improve the shortage of MPS’s machine supervisor control and data acquisition system
