RESEARCH AND DEVELOPMENT OF ONLINE-REALTIME SUPERVISING SYSTEM FOR LOW VOLTAGE GRIDS
Keywords:Smart grid; Smart transformer; Supervising; Managmement; Low voltage.
This paper presents some results of fabrication and experiment of an online-realtime supervising system for low voltage grids. The experiment results show that, for the proposed system, important operating parameters of the low voltage grid such as voltage, current, power, temperatures of oil, cable are supervised and analyzed. Additionally, alarming messages are sent to operators immediately when there are abnormal phenomenon occurring at the grid. This proposed system can help improve reliability of electric supply and reduce SAIDI, SAIFI, as well as enhance safety of human being and equipment.
