ABB Relion REC670 - Setting Example; Comparator for Real Inputs - REALCOMP; Identification; Application

15.13.4 Setting example
GUID-13302FD6-1585-42FE-BD6D-44F231982C59 v1
For absolute comparison between inputs:
Set the
EnaAbs = 1
Set the RefSource = 1
Similarly for Signed comparison between inputs
Set the
EnaAbs = 0
Set the RefSource = 1
For absolute comparison between input and setting
Set the
EnaAbs = 1
Set the RefSource = 0
SetValue
shall be set between -2000000000 to 2000000000
Similarly for signed comparison between input and setting
Set the
EnaAbs = 0
Set the RefSource = 0
SetValue shall be set between -2000000000 to 2000000000.

15.14.2 Application
GUID-5F7B1683-9799-4D27-B333-B184F8861A5B v1
The function gives the possibility to monitor the level of real values in the system relative to
each other or to a fixed value. It is a basic arithmetic function that can be used for monitoring,
supervision, interlocking and other logics.
15.14.3 Setting guidelines
GUID-DE69FF5B-7D34-4A30-9060-214E98BFF798 v1
Setting procedure on the IED:
EnaAbs : This setting is used to select the comparison type between signed and absolute
values.
• Absolute : The function will do absolute comparison between input and reference value.
•
Signed : The function will do signed comparison between input and reference value.
