EVIEW middle and low voltage intelligent transformer and distribution system
System overview
EVIEW of low voltage intelligent distribution management system USES the modern computer control technology, automation technology and network technology, through the efficient and reliable communication equipment, the intelligent power distribution equipment operation data and status information collection and management, through the system software configuration, eventually achieve effective improve the reliability of power supply and distribution system and operation management level.
System architecture
EVIEW middle and low voltage intelligent transformer and distribution management system is based on the architecture of "three-layer distribution, two networks, one integrated". It is composed of the equipment layer, the communication layer and the main station layer, and is connected by the field bus and the Ethernet network to form an organic whole.
Equipment layer:
Equipment layer equipment, namely remote terminal equipment (RTU), is used for data acquisition and transmission of field monitoring signals. The equipment layer is composed of various intelligent instruments, microcomputer protection devices and other third party intelligent equipment needed in middle and low voltage distribution monitoring.
The communication layer:
The communication layer is mainly used for signal conversion and data transmission between field equipment and system background. The communication layer consists of industrial network switch, communication manager, rs232/485 industrial isolator, photoelectric converter and power module.
The main layer:
The main station layer is based on SmartPM3000 middle and low voltage intelligent transformer and distribution management system software, which can display and process the data and control signals collected by the equipment layer in real time. The operation interface of the system is simple and intuitive, which really realizes the connection between the user and the monitoring equipment. The main station layer is composed of monitoring mainframe, printer and UPS uninterruptible power supply.
