Data Acquisition From External Distribution Management System (DMS) Network Monitoring Subsystem
Abstract:

This use case describes how an Energy Management System (EMS) could get analogue and status measurement data from an external Network Operations – Network Monitoring (NONMON) subsystem within a Distribution Management System (DMS). The measurement data could originate from a variety of sources including Remote Terminal Units (RTU), networked Intelligent Electrical Devices (IEDs), manual data entry or calculations within the Network Operations system. The NO-NMON subsystem will present all measurement information in a consistent manner regardless of the source. Data maintenance and Telemetry network maintenance are considered separate use cases but relevant Actors and Systems are shown for reference. This use case includes a very simple form of data discovery which returns a numeric key if a named measurement exists and an error return code if a named measurement does not exist. It is assumed that the EMS has some rules to define the set of names that it will attempt to discover. This use case assumes a single context for all information exchanges.
