The PRS-3351 intelligent feeder terminal independently developed by CYG SUNRI can provide the functions of fault detection, information upload, control command acceptance and execution. In addition to remote metering, remote signaling and remote control and line loss management, it also supports various FA methods and other distribution line state perception and edge processing function such as intelligent distributed feeder automation. The system can achieve power collection and control, fault detection, fault area location, isolation and power recovery in non-fault area, which can improve the reliability of power supply.

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.
