Compared with a power transmission network, the power distribution network has the characteristics of complex wiring, multiple equipment quantity and low automation degree. To achieve the desired benefits, distribution automation systems require a certain number of terminals to be installed. The terminal quantity is many in the distribution network, and terminal operational environment is abominable, and the equipment quality of different producers is uneven, and the distribution network reforms transform frequently, and these factors lead to distribution automation terminal equipment to insert and maintain the work load huge, and in addition terminal equipment fortune dimension personnel quantity is not enough and fortune dimension horizontally restriction, has influenced distribution automation system's practical application and popularization. Therefore, the workload of access debugging of the distribution automation terminal is reduced, the terminal is accessed through simple configuration and even accessed through 'plug and play', and the method becomes a hot problem of research in the field of distribution automation in recent years.
The IEC61850 standard is successfully applied to the intelligent substation, and a technical path is provided for IEDs of different manufacturers to interoperate. However, due to the complexity of IEC61850 and the adaptability of IEC61850 to power distribution networks, the implementation of "plug and play" of distribution automation terminals based on the coordination and conversion of IEC61850 and IEC61970 protocols is still in a theoretical research stage, and there are many problems to be researched and solved from practical application.
