The following is a brief overview of the applications that are considered as part of the ADMS functionality in the Oracle Utilities Network Management System. A full description of each application is given in the following sections.

Power Flow:

The Power Flow application is the core of the ADMS functionality, most other ADMS applications depend on the Power Flow module.

This module calculates the voltages at every bus in the system and from that derives the current flows along with the real and reactive load flows. When analyzing the real-time model, it can incorporate data from SCADA to scale the loads appropriately. It will also utilize historical load profiles (if present) to refine the results.

Feeder Load Management (FLM):

The FLM application is intended to provide a system wide overview of the current loading conditions on the network and optionally future loading scenarios.

Fault Location, Isolation and Service Restoration (FLISR):

The FLISR application is for finding ways to restore power to customers that have been unexpectedly de-energized, typically due to a fault. It is triggered by a breaker lockout and it seeks to identify the faulted section. Through the use of SCADA controllable switches, it will formulate a plan to isolate the faulted section and restore service to customers above and below the faulted section where possible.

Fault Location Analysis (FLA):

The FLA application predicts the location of faults using fault currents reported from the relay of the tripped device. It uses short-circuit analysis to determine the probable fault locations that may exist on a feeder.

Optimization:

The Optimization application continuously monitors the distribution system looking for opportunities to optimize performance to meet pre-configured objectives.

Suggested Switching (SS):

The SS application runs only in Study Mode and is used to create planned switch sheets that allow certain operations to be performed with minimum customer interruptions whilst preventing other issues like ratings or voltage violations.
