Created: 17 Jun 2011

Status: In Force (green)

Part: Part 7-4 (2010; Edition 2)



Clause: 5.10.12


Category: Issue may impact interoperability of implementations of Edition 2


The data object PFSign in MMXU is an enumeration to set the used convention for the power factor sign. In the inverter industry the PFSign will have another value: exitation (underexited/overexited).
This value will be used in IEC 61850-90-7.


Add the enum value for PFSign: 3 - Exitation (Overexited for the quadrant 1 and 2 , underexited for the quadrant 3 and 4). Change the semantic description accordingly.

WG17 propose the attached figures for PFSign convention.

The values for PFSign should be:

The proposal to extend the enum list by adding "3-Excitation" should be rejected according with IEC 61850-90-7 (Inverter model). Excitation will be managed by seperate data objects (FPFW.PFExtStr/FPFW.PFExtStop - excitation of start/stop point).
