CIM-61850 Harmonization - Add string attribute psrType to tPowerSystemResource.
IEC 62361-102 Recommendation R3
5.6.4 Recommendation for harmonization: SCL PSRType
In the CIM, instances of power system resources may be associated with zero or one
instances of PSRType. This is used for “classifying instances of the same class, e.g.
overhead and underground ACLineSegments. This classification mechanism is intended to
provide flexibility outside the scope of this standard, i.e. provide customisation that is nonstandard.”
This custom classification is particularly useful for modelling distribution network equipment,
as a way of defining individual instances with reference to template or catalogue objects that
contain sets of reference parameters.
It would also help mapping algorithms to choose the appropriate CIM class when there is a
choice, e.g. a physical line could be modelled as an ACLineSegment, but for transmission
network applications it could be modelled as an EnergyConsumer (a point of consumption on
the power system model)
Recommendation R3: An optional string attribute psrType should be added to the SCL
definition for tPowerSystemResource. It may be appropriate to use a specific namespace for
this and other CIM related attributes.
Add optional string attribute psrType to the SCL definition for tPowerSystemResource. It may be appropriate to use a specific namespace for this and other CIM related attributes.
