The functional measured values of Δφ in HMI are displayed differently in the following situations:
•
If the Vector-jump protection function is inactive, the function value of Δφ is displayed as “---”
•
If the Vector-jump protection function is active and has not picked up, the functional measured value of
Δφ is displayed as 0.0°
•
If the Vector-jump protection function is active and has picked up, the functional measured value of Δφ
is displayed as a calculated value (for example, 12.0°) and remains unchanged until the next pickup of
the Vector-jump protection function.
Application and Setting Notes
Parameter:
Threshold V1 min
•
Default setting
(_:2311:102) Threshold V1 min
=
46.189 V
With the parameter
Threshold V1 min
, you can define the minimum threshold of the voltage band.
The setting value is closed to the allowed lower limit of the voltage band. The default setting is 80 % of the
rated positive-sequence voltage. The value of the rated positive-sequence voltage is 100 V/√3.
Parameter:
Threshold V1 max
•
Default setting
(_:2311:101) Threshold V1 max
=
75.058 V
With the parameter
Threshold V1 max
, you can define the maximum threshold of the voltage band.
The setting value is closed to the allowed higher limit of the voltage band. The default setting is 130 % of the
rated positive-sequence voltage. The value of the rated positive-sequence voltage is 100 V/√3.
Parameter:
T Block
•
Default setting
(_:2311:6) T Block
=
0.10 s
With the parameter
T Block
, you set the dropout delay of the Δφ stage.
When voltages are connected or disconnected, the overfunction can be avoided with the timer
T Block
.
Siemens recommends to use the default setting of the parameter
T Block
. Keep in mind that the parameter
T Block
has always to be set to 2 cycles more than the measuring window for vector-jump measurement.
