I
IED Parameter Set
All the parameter values needed for the definition of the behavior of the IED and
its adaptation to the substation conditions. Where the IED has to operate
autonomously, the IED-parameter set can be generated without system
parameters using an IED-specific parameterization tool. Where the IED is a part
of the SAS, the IED-parameter set may include system parameters, which must
be coordinated by a general parameterization tool at the SAS level.
Implementation
Development phase in which the hardware and software of a system become
operational.
Information Model
Knowledge concerning substation functions (devices) made visible and
accessible through the means of the IEC 61850 series. The model describes in
an abstract way a simplified representation of a real function or device.
Inspection
Activity such as measuring, examining, testing or gauging of one or more
characteristics of an entity and comparing the results with specified requirements
in order to establish whether conformity is achieved for each characteristic.
Instance
Entity that has a unique identity, with the attributes of a defined class, to which a
set of services can be applied and which has a state that stores the effects of the
services. 'Instance' is synonymous with 'object.'
Instance Name
Identifier associated with and designating an instance.
Instantiation
Creation of an instance of a specified class.
Intelligent Electronic Device (IED)
Device that contains at least one processor and that can exchange data with
other Intelligent Electronic Devices.
Interchangeability
Ability to replace a device supplied by one manufacturer with a device supplied
by another manufacturer, without making changes to the other elements in the
system.
Interface
A boundary across which two systems communicate using common functional
characteristics, for example: common physical interconnection or signal
characteristics.
