Description

IEC 62361-102 Recommendation R2

The list of device type codes in IEC 61850-6 should be extended to correspond better with the IEC 61970 / IEC 61968 Common Information Model, particularly to support applications related to distribution networks. This would allow the Substation section to be used to more fully describe the power system equipment and its connectivity without needing any details of Logical Nodes. The aim is that the type code indicates the fundamental nature of the physical equipment, not necessarily its usage within a particular software application.

See attached document

Details:
1) Add new type codes for Busbar section and Junction. Conducting Equipment of these
types would be defined within Bays together with their associated Terminal and ConnectivityNode.
2) Add new type codes to distinguish types of switch. DIS is ambiguous as it can be mapped
to several different sub-types of CIM Switch.
3) It is confusing to have type codes for device types with a variable number of terminals.
Add new type codes to distinguish series and shunt capacitors.
4) It is confusing to have type codes for device types with a variable number of terminals.
Add new type codes to distinguish series and shunt reactors.
5) It is not clear what the difference is between type code CON “converter” compared with
the SCR “rectifier” and TCF “frequency converter”. The type code CON should be deprecated.
6) Add new type code for Composite Switches i.e. a set of individual Switches normally
enclosed within the same cabinet and possibly with interlocks that restrict the combination
of switch positions. These are typically found in medium voltage distribution networks or
high-voltage gas insulated switchgear. The purpose is to allow the cabinet or cubicle to be
represented as equipment with its own identity and status, in addition to its constituent
switches.
7) The IFL type code should not be used for new designs. The differentiation with between
outgoing and infeeding lines is not relevant in many transmission networks and is
becoming artificial in distribution grids with high level of dispersed generation. The power
flow direction may change in a few seconds. Allow LIN and CAB to be modelled with one
terminal when they cross the substation or system border, and modelled with two
terminals if the SCL models a full line.
8) For CIM applications, there are fundamental differences between AC and DC equipment.
It is complex to distinguish AC lines and DC lines based on the association with a voltage
level that has a frequency attribute with value zero. Add new type codes DLN and DCA.
