Firstly, the characteristics of active distribution network(ADN), control resources and process control under various operating conditions are analyzed in this paper. In order to implement ADN process control in a variety of operating state, an active distribution network management system(ADMS)based on SCADA platform technology is designed. ADMS includes comprehensive operation and decision-making system, distribution automation system, active load management system, etc. Through information exchange, assist control and unified operation management of subsystems, the global optimization operation and regional coordinated operation control under grid connected status, fault location and fast recovery power supply operation control under fault status and the isolated network operation control of ADN under off-network status can be carried out in ADMS, and the loads under various operating conditions can be actively controlled and managed to meet the ADN operational requirements. ADMS operates reliablely in the experiment platform, and provides the reference for further study of ADMS.
