Hệ thống tự động hóa trạm phân phối

Background

Distribution Automation is an important part of today’s Smart Grid. Integration and interoperability are essential for grid operational efficiency and system reliability. Smart Grid technologies around the world are helping to reduce power outages & identify the root causes of blackouts and brownouts; improving restoration times and cutting operational costs.
Project requirements
Distribution network communication often exposed to the outdoors, sunlight and rain and snow and other natural conditions of interference, but also by the external electromagnetic interference. This requires that the communication system can work reliably at any time.
In the power distribution network power failure or other faults, can quickly capture the failure information, ensure that the failure notification information effectively, fast transmission.
It can effectively upload the collected data and control commands to the related equipment.

Scheme introduction
In this scheme, the three layer structure is adopted. The whole network is divided into three parts: core layer, convergence layer and access layer.
Communication system can be divided into three levels. The first layer is the communication between the master station and sub station
The second layer is the communication between the substation and the terminal equipment (DTU, FTU, etc.) in the main line.
The third layer is the communication between the terminal equipment.
Scheme advantage
Design for industrial Level 4 standard, the working temperature -40 ~ 75℃, to meet a variety of industrial field environment.
SW-Ring ring network, network fault self healing time <20ms, guarantee network stability
Dual power input, support power redundancy
Relay alarm, real-time monitoring equipment link status, and timely feedback fault information
Provide related software to support the automatic discovery, batch configuration and other functions, simplifying the implementation and maintenance of the project.
