Dynamic SCADA prototype system construction and implementation of communication system

The development of smart distribution grid strongly depends on the establishment of reliable communication platform. Nowadays,communication between stations is increasing rapidly and real-time data of the whole network is required,which SCADA and WAMS could not provide. This paper proposed a method to upgrade SCADA into dynamic SCADA by installing a new equipment called dynamic RTU. On this basis,the paper built a prototype system and proposed an analysis of the traditional implementation of IEC104 protocol communication and pointed out its shortcoming. And implementation of the non-blocking 104 protocol communication using the non-blocking implementing method significantly improves communication performance in the dynamic SCADA.
