Verification of the

ACCALARM

value and time delay to operation

1. Connect the test set for the injection of three-phase currents and three-phase

voltages to the appropriate current and voltage terminals of the IED.

2. Ensure that the settings in the IED are appropriate for the default settings,

especially the

CurrStartLevel

,

FreqHighLimit

,

FreqLowLimit

,

UHighLimit

and

ULowLimit

setting.

3. Supply the IED with three-phase currents and voltages at their rated value.
4. Slowly decrease the frequency of the applied voltage until it crosses the

frequency high limit and the

START

signal appears.

5. Continuously change the frequency of the applied voltage, so that for a certain

time the frequency is outside the set band limit and falls gradually within the band
limit.

6. Count only the time when the frequency lies within the set frequency band limit.

Wait for a time corresponding to

tAccLimit

and ensure that the

ACCALARM

signal

appears.

7. Measure the time delay for the

ACCALARM

signal and compare it to the set value.

Extended testing

1. To check the value of

TRIPACC

, repeat the above test case in such a way that the

frequency of the applied voltage is within the set frequency band when time
approaches the

tAccLimit

setting value.

Verification of generator start and stop logic

1. Ensure that the settings in the IED are appropriate to the default settings,

especially the

CurrStartLevel

,

FreqHighLimit

,

FreqLowLimit

,

UHighLimit

and

ULowLimit

.

2. Ensure that the setting

CBCheck

is enabled.

3. Supply the IED with three-phase currents and voltages at their rated values.
4. Slowly decrease the frequency of the applied voltage until the

START

signal

appears.

5. Activate the

CBOPEN

input signal.

6. Slowly decrease the injected current below the

CurrStartLevel

value until the

START

signal disappears.

7. Compare the current magnitude value to the set value.

Verification of voltage band limit check logic

1. Ensure that the settings in the IED are appropriate to the default settings,

especially the

CurrStartLevel

,

FreqHighLimit

,

FreqLowLimit

,

UHighLimit

and

ULowLimit

settings.

2. Ensure that the

EnaVoltCheck

is enabled.

3. Supply the IED with three-phase currents and voltages at their rated values.
4. Check that the

VOLTOK

signal appears.

5. Slowly decrease the frequency of the applied voltage until the

START

signal

appears.
