Siemens SIPROTEC 5 User Manual

Mode
The trigger is switched on, off, or in test mode. In test mode, the fault records are marked with a test flag.
You can find more detailed information on the mode in chapter 7.1.3 Step 2: Setting the Parameters and
Routing in DIGSI 5 .
Switching on Trigger Max./Trigger Min.
With the parameters Max. trigger active and Min. trigger active, you define whether the respec-
tive level trigger is active or inactive.
Trigger Max./Trigger Min.
With the parameters Max. trigger and Min. trigger, you define from which threshold value the acti-
vated level trigger starts a fault record.
Switch on dM/dt Rise - dM/dt Drop
With the parameters dM/dt rise active and dM/dt drop active, you define whether the respective
gradient trigger is active or inactive.
Filter Time
With the Filter time parameter, you define the number of periods with which the gradient is determined.
Gradient Trigger for Rising and Dropping Gradients of the Active, Reactive, and Apparent Power
With the parameters dM/dt rise (/Filter time) and dM/dt drop (/Filter time), you define
from which threshold value within the set filtering time a fault record is started.
Application and Setting Notes – Trigger P
Parameter: Mode
•
Default setting (_:19411:1) Mode = off
With the Mode parameter, you activate the trigger for normal operation (On) or the test mode (Test).
Parameter Value
Description
on
The Trigger P function block is activated and the sum active power is moni-
tored according to the set trigger parameters.
off
The Trigger P function block is deactivated.
test
The Trigger P function block is activated for test purposes.
Parameter: Power Direction
•
Default setting (_:19411:111) Power direction = positive
With the Power direction parameter, you can trigger on negative powers if the parameter is set to nega-
tive.
Parameter Value
Description
positive
This setting value has no influence on the trigger thresholds.
negative
This setting value multiplies the trigger threshold by -1.
Parameter: Max. Trigger Active/Max. Trigger/Max. Trigger Hysteresis
•
Default setting (_:19411:101) Max. trigger active = yes
•
Default setting (_:19411:105) Max. trigger = 0 W
•
Default setting (_:19411:113) Max. trigger hysteresis = 0.980 p.u.
