AEP Circuit Reconfiguration
Abstract:

This use case describes how the system will use the circuit reconfiguration controller (CRC) to handle faults and restoration automatically.
In the use case, a fault occurs on the distribution system and the Fault Clearing Device clears the fault. The Fault Clearing Device sends the lock out signal to the Circuit Reconfiguration Controller (CRC). The CRC sends the lock out information to the Distribution SCADA (D-SCADA)/DMS, the Outage Management System (OMS), and Distribution Historian. The CRC sends an abnormal control area configuration status to any applicable Volt-Var Controller. By polling the various devices, the CRC is able to perform a fault isolation calculation to isolate the fault. The CRC then sends a device command to the Isolation Device which acknowledges the command and performs the functions needed to isolate the fault. These events are monitored in the D-SCADA through regular polling of the devices. The CRC eventually calculates the reconfiguration scenario and sends the commands to the Reconfiguration Device which acknowledges the commands. After the Reconfiguration Device functions, it sends an update to the CRC which sends all equipment status updates to D-SCADA which updates the Distribution Historian.
