PRS-3000 distribution master station
CYG SUNRI designed a new generation of intelligent distribution network "self-healing" system based on IEC 61968 / IEC 61970 and the latest standards. By collecting the information of distribution network within the scope, various functions are realized, such as operation monitoring, operation state control, access and control of distributed power, self-healing control, and economic and optimized operation of the distribution network, so as to improve the reliability of power supply, reduce line loss of power grid, improve power quality, power supply capacity and management level, and reduce the operating costs.

Scope of Application

Itis applicable to provincial, prefecture, municipal, and county-level power distribution networks, as well as the power distribution networks of 20kV and below in various enterprises.

Advantages
01
With uniform service and system management functions, it can provide plug-and-play of different applications, and support deployment of integrated applications.
02
A cross-platform solution integrating graph/model/library is provided, which can achieve multi-scenario applications in the whole network in real time.
03
Various architecture techniques are adopted, including distributed collection, network load balancing and parallel data processing, and it can efficiently process massive data with fault tolerance.
04
