In de-energized scenarios, applying a workaround by isolating a short section of a line can cause incorrect subnetwork assignment—e.g., the section may inherit the subnetwork name from the downstream feeder. This leads to inconsistent behavior and potentially misleading information in ADMS, which may raise safety concerns.
Key observations:
-Initial tests showed that a line simulating a tie switch displayed different subnetwork names at each end—an inconsistency that challenges the reliability of this workaround.
-Introducing temporary (dummy) switches in ArcGIS helps avoid error 29, but these switches don’t exist in the real network and appear in ADMS, introducing data integrity and operational risks.
-Isolated network sections without proper subnetwork assignment may result in incorrect delegation when exported to ADMS.
-Merging subnetworks creates new feeders, requiring deletion and re-export of all related MV/LV feeders. This can mislead operators if existing feeder names are changed, which is typically discouraged.
-Use of temporary network elements has been questioned due to safety concerns in control room operations.
Looking for a more reliable way to handle de-energized phases without incorrect subnetwork assignments or the need for dummy switches. The goal is to maintain data integrity and safety in ADMS without introducing non-existent elements or confusing feeder names.
