ABB RELION REC650, Commissioning Manual

Page: 75 / 130

When the IED is brought into normal service it is recommended to delete all events
resulting from commissioning tests to avoid confusion in future fault analysis. All
events in the IED can be cleared in the local HMI under
Main Menu//Clear/Clear
internal event list or Main menu/Clear/Clear process event list . It is not
possible to clear the event lists from PCM600.
When testing binary inputs, the event list (EL) might be used instead. No uploading
or analyzing of registrations is then needed since the event list keeps running,
independent of start of disturbance registration.
9.2 Identifying the function to test in the technical
reference manual
M11748-2 v4
Use the technical manual to identify function blocks, logic diagrams, input and
output signals, setting parameters and technical data.
9.3 Multipurpose protection
SEMOD53552-1 v1
9.3.1 General current and voltage protection CVGAPC
SEMOD56488-3 v3
Prepare the IED for verification of settings as outlined in section "Requirements"
and section "Preparing for test" in this chapter.
One of the new facilities within the general current and voltage protection function
CVGAPC is that the value, which is processed and used for evaluation in the
function, can be chosen in many different ways by the setting parameters
CurrentInput and VoltageInput .
These setting parameters decide what kind of preprocessing the connected three-
phase CT and VT inputs shall be subjected to. That is, for example, single-phase
quantities, phase-to-phase quantities, positive sequence quantities, negative
sequence quantities, maximum quantity from the three-phase group, minimum
quantity from the three-phase group, difference between maximum and minimum
quantities (unbalance) can be derived and then used in the function.
Due to the versatile possibilities of CVGAPC itself, but also the possibilities of
logic combinations in the application configuration of outputs from more than one
CVGAPC function block, it is hardly possible to define a fully covering general
commissioning test.
