Review
Systematic examination, as defined in the appropriate document, of the quality
document(s) for an activity. The test facility must provide the documentation to be
reviewed to the initiator of the conformance test at an agreed time prior to the
associated hold or witness point. How the review is conducted is subject to
agreement.
S
SAS Installation
Concrete instance of an SAS consisting of multiple, interoperable IEDs from one
or more manufacturers.
SAS Parameter Set
All the parameters needed for the definition of the behavior of the overall SAS
and its adaptation to the substation conditions. The SAS parameter set includes
the IED parameter sets of all participating IEDs.
SAS Product Family
Range of different IEDs from one manufacturer, with various functionalities and
with the ability to perform substation automation system functions. The IEDs of a
product family are unified in relation to the design, the operational handling, the
mounting and wiring requirements and they use common or coordinated
supporting tools.
Scalability
Criterion for a cost-effective SAS, taking into account the various functionalities,
IEDs, substation sizes and substation voltage ranges.
Secondary System
Interaction set of all components and systems in the substation for the operation,
protection, and monitoring of the primary system. In case of full application of
numerical technology, the secondary system is synonymous with the substation
automation system (SAS).
Selector
Defines the references to a class instance for accessing the instance values.
Self-Description
Device contains information on its configuration. The representation of this
information has to be standardized and has to be accessible via communication
(in the context of the IEC 61850 series).
Server
On a communication network, a functional node that provides data to, or that
allows access to its resources by, other functional nodes. A server may also be a
logical subdivision, which has independent control of its operation, within the
software algorithm (and/or possibly hardware) structure.
