The distribution network feeder line information awareness is weak, with many lines unable to collect or transmit even basic telemetry and remote signaling information, creating information blind spots.
Some existing feeder automation devices have low fault detection accuracy and slow fault isolation speed, posing the risk of fault area expansion.
Current systems have slow fault recovery speeds, and some lack self-healing functionality, failing to meet the increasing requirements for power supply reliability.
As a large amount of distributed new energy is integrated into the distribution network feeder, the existing system is unable to support the bidirectional power flow changes in the distribution network and meet the real-time control requirements.
The new distribution feeder automation system includes the distribution network automation main station system, intelligent feeder terminal, and intelligent substation terminal, realizing information monitoring, remote control, relay protection, fault isolation, and fault self-healing functions for distribution network feeder lines. It meets real-time monitoring requirements for various operational indicators of the line, while achieving rapid isolation of line faults and restoring power to non-fault areas within seconds, improving the reliability and safety of the distribution network.
