Abstract: The paper, supported by main network of SCADA system and distribution network of DSCADA system, makes analysis of the access of distribution network stations, the function improvement and value mining of distribution automation system and the real-time monitoring of important users based on the current situation of the distribution network management. It explores the switch station access method and seeks the feasible scheme of comprehensive access of switch station to improve the observable, measurable and controllable level of distribution networks. The intelligent monitoring and analysis function of distribution network information is analyzed to improve the schedule monitoring efficiency of massive signals, and help the schedule deal with defects and faults to ensure the safe and stable operation of distribution network. Moreover, it constructs a real-time monitoring platform for important users, carries out centralized monitoring of the whole path of user power supply to perceive user anomalies in time, and uses monitoring results for fault repair and hidden dangers elimination,which improves the service of users’ access to electricity and ensures the power supply reliability of distribution networks.
