21.4 Parameter setting groups
21.4.1 Application
Six sets of settings are available to optimize IED operation for different power system conditions. By
creating and switching between fine tuned setting sets, either from the local HMI or configurable
binary inputs, results in a highly adaptable IED that can cope with a variety of power system
scenarios.
Different conditions in networks with different voltage levels require highly adaptable protection and
control units to best provide for dependability, security and selectivity requirements. Protection units
operate with a higher degree of availability, especially, if the setting values of their parameters are
continuously optimized according to the conditions in the power system.
Operational departments can plan for different operating conditions in the primary equipment. The
protection engineer can prepare the necessary optimized and pre-tested settings in advance for
different protection functions. Six different groups of setting parameters are available in the IED. Any
of them can be activated through the different programmable binary inputs by means of external or
internal control signals.
A function block, SETGRPS, defines how many setting groups are used. Setting is done with
parameter MAXSETGR and shall be set to the required value for each IED. Only the number of
setting groups set will be available in the Parameter Setting tool for activation with the ActiveGroup
function block.
21.4.2 Setting guidelines
The setting ActiveSetGrp, is used to select which parameter group to be active. The active group can
also be selected with configured input to the function block SETGRPS.
The length of the pulse, sent out by the output signal SETCHGD when an active group has changed,
is set with the parameter t.
The parameter MAXSETGR defines the maximum number of setting groups in use to switch
between. Only the selected number of setting groups will be available in the Parameter Setting tool
(PST) for activation with the ActiveGroup function block.
