In order to improve this situation, the automatic construction of power distribution networks has been in force.
The distribution network automation utilizes modern electronic technology, communication technology, computer and network technology to integrate real-time information, off-line information, user information, power grid structure parameters and geographic information of a distribution network to form a complete automatic management system, and monitoring, protection, control and distribution management of a distribution system under normal operation and accident conditions are realized. The distribution network automation system is a system integrating real-time distribution automation and a distribution management system.
The distribution network automation system generally adopts a layered distribution system structure and is composed of a main station, a substation and a distribution terminal. The distribution network automation master station is a core part of a distribution network automation system, mainly realizes basic functions of distribution network data acquisition, monitoring and the like, and extended functions of distribution network topology analysis application and the like, has a function of information interaction with other application information systems, and provides technical support for distribution network scheduling command and production management.
Preset, send preset signal to distribution terminal through distribution network automation main website promptly, the inspection communication, whether normal common means in FTU logic circuit, traditional distribution automation main website when presetting in batches to a large amount of distribution terminals, assign preset instruction simultaneously to a large amount of distribution terminals usually, distribution terminal also returns the order almost simultaneously, this operation can cause whole distribution network automation system's communication channel to block up seriously, cause huge pressure to the server, not only can cause normal equipment signal to lose, normal terminal presets the failure, other works that probably influence distribution automation main website in addition, cause serious influence to the electric wire netting steady operation.
