6.4.7.2 Completing the test
Continue to test another function or end the testing by setting the parameter
TestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No under Main menu/
Tests/Function test modes/Current/CCRPLD(52PD)/X:CCRPLD for the
function, or for each individual function in a chain, to be tested next. Remember to
set the parameter Blocked to Yes, for each individual function that has been tested.
6.4.8 Directional underpower protection GUPPDUP
Prepare the IED for verification of settings as outlined in
5.1 "Preparing the IED to
verify settings".
Values of the logical signals for GUPPDUP are available on the local HMI under
Main menu/Tests/Function status/Current/GUPPDUP(37,P<)/1:GUPPDUP.
The Signal Monitoring in PCM600 shows the same signals that are available on the
local HMI.
6.4.8.1 Verifying the settings
The underpower protection shall be set to values according to the real set values to
be used.
The test is made by means of injection of voltage and current where the amplitude
of both current and voltage and the phase angle between the voltage and current
can be controlled. During the test the analog outputs of active and reactive power
shall be monitored.
1. Connect the test set for injection of voltage and current corresponding to the
mode to be used in the application. If a three-phase test set is available this
could be used for all the modes. If a single-phase current/voltage test set is
available the test set should be connected to a selected input for one-phase
current and voltage.
Use the formulas stated in
Table 2 for the different calculation modes used.
The set mode Mode can be found on the local HMI under Main menu/
Settings/IED Settings/Current/GUPPDUP(37,P<)/1:GUPPDUP/General.
