Adaptive Parameter Sets are part of the “Device Parameter tree”.
By means of
Adaptive Parameter Sets, the User can temporarily modify single parameters within the Parameter Setting
groups.
Adaptive Parameters drop-out automatically if the acknowledged signal that has activated
them has dropped-out. Please take into account that Adaptive Set 1 is dominant to
Adaptive Set 2. Adaptive Set 2 is dominant to Adaptive Set 3. Adaptive Set 3 is dominant
to Adaptive Set 4.
In order to increase the usability (clarity), Adaptive Parameter Sets become visible if a
corresponding activation signal has been assigned (
PowerPort-E
V. 1.2 and higher).
Example: In order to use Adaptive Parameters within Protective Element
I
[1], please
proceed as follows.
Assign within the Global Parameter tree, within Protective Element I[1], an activation
signal for Adaptive Parameter Set 1.
Adaptive Parameter Set 1 becomes now visible within the Protection Parameter Sets for
element I[1].
By means of additional activation signals, further Adaptive Parameter Sets can be used.
The functionality of the IED (relay) can be enhanced / adapted, by means of
Adaptive Parameters in order to meet the
requirements of modified states of the grid or the power supply system respectively, to manage unpredictable events.
Moreover, the adaptive parameter can also be used to realize various special protective functions or to expand the
existing function modules in a simple way, without costly redesign the existing hardware or software platform.
The
Adaptive Parameter feature allows, besides a standard parameter set, one of the four parameter sets labeled from
1 to 4, to be used, for example, in a time overcurrent element under the control of the configurable Set Control Logic.
The dynamic switch-over of the adaptive parameter set is only active for a particular element when its adaptive set
control logic is configured and only as long as the activation signal is true.
For some protection elements, such as time overcurrent and instantaneous overcurrent ( 50P, 51P, 50G, 51G, …),
besides the “default” setting there exists another four “alternative” settings for pickup value, curve type, time dial, and
reset mode set values that can dynamically be switched-over by means of the configurable adaptive setting control
logic in the single set parameter.
If the
Adaptive Parameter feature is not used, the adaptive set control logic will not be selected (assigned). The
protective elements work, in this case, just like a normal protection using the “Default” settings. If one of the
Adaptive
Set Control logic is assigned to a logic function, the protective element will be “switched-over” to the corresponding
adaptive settings if the assigned logic function is asserted and will drop-out to the “Default” setting if the assigned signal
that has activated the
Adaptive Set has dropped-out.
