Applies to:
Oracle Utilities Network Management System - Version 2.4.0.1.0 to 2.5.0.2.0 [Release 2.4 to 2.5] Oracle Network Management for Utilities - DMS - Version 2.4.0.1.0 to 2.5.0.2.0 [Release 2.4 to 2.5] Information in this document applies to any platform.
Symptoms
On : 2.5.0.1.0 version, NMS Infrastructure
The Power flow engine is not utilizing the per phase scada voltage measurements present on the Substation transformers and still regulating voltages through a ganged set point for all three phases. If the scada voltage measurements are present on the Bus PT downstream of Sub LTC, they are used and voltages are trued up.
Per-Phase SCADA voltages should always be used if present.
