碩士 === 國立高雄應用科技大學 === 電機工程系博碩士班 === 101 === This thesis proposes to apply inverter control technique to establish a transformer energy saving remote supervisory control and data acquisition (SCADA) system in order to save energy and without violating transformer operation constraints and requirements. Main transformer fan group control modes which consists of both group-section control mode and inverter control mode is to apply hardware of programmable logic controller and thermal electric component as well as software of control strategies to implement proposed system. Furthermore, backend of proposed system which is bulit in windows based operating environment with the SQL Server database structure to establish functions. Besides, proposed system is also designed with the property of untied mechanism which can restore original operation mode of fan during the artificial demands or emergency status. Finally, through on site test in Renwu E/S, the obtained achievements can be applied to verify energy saving efficiency as for a reference for installing and implementing a practical transformer in the future.
