This system is a domestic distribution network management system with graphic visualized information that integrates SCADA(Supervisory Control and Data Acquisition), GIS(Geographic Information System), and distribution power flow programs. It provides feeder geospatial information and positioning services, and displays power generation information of electric devices and renewable energy on feeders through data visualization technique, which can assist dispatchers to quickly track the fault locations on feeders. Besides ability to conduct fast FDIR, with distribution flow calculations, SCADA can also provide important information such as feeder margin, maximum/ minimum voltage, and line loss for dispatchers as a reference for decision-making to speed up troubleshooting and restoration of user power supply. It is expected that the proposed system can enhance the reliability of feeder dispatch operation and the ability to manage renewable energy.
