e L0-1U-11202-007-01-C1 Respond To Diesel Generator Generator Alaras PrKFORMANCE OBJECTIVE Given that a generator alarm associated with the diesel generator tas i
annunciated, respond to the diesel generator "generat.or" alarm.
All communication and activities niust be performed in accordance with current. approved procedures.
The alarm must be acknowledged and its validity determined.
A plant equipment operator must be dispatched to petform activities locally, as necessary.
The diesel generator must be returned to operational status if it becomes inoperable due to the alarmed condition.
INFORMATION in this instructional unit.. the following generatar ala.ms associated with the diesel generator are covered:
DGIA GENERATOR TROUBLE DGI A LOW VOLTAGE DCIA HIGH TEMP GEN CNTL PNL DGIA LOW EXCITATION DGIA TRIP GENERATOR PAULT DGIA TRIP GEN DIFF DCI A HIGH TDtP GEN BEARINGS DGI A GENERATOR UNDER FREQUENCY DGIA DISABLED GEN CONTROL PVR FAILURE (wes covered in previous clustrt with other DISABLED alarms)
Upon receipt of any one of the diesel generstor alarms, obtain Plant Vogtle Annunciator Response Procedure 17035-1, and acknowledge the alarm. Also depress the SII.ENCE push button to silence the alarm horn.
When responding to any one of the diesel generator alarms:
s 1.
Acknowledge the alarm.
When acknowledging the alarm note any other alarm that may have annunciated associated with this alarm.
2.
Investigate the alarm.
Perform the initial Cperator actions required for the appropriate alarm as listed in the procedure. Dispatch a PE0 to perform the local subsequent operator actions as listed in the procedure.
Determine the validit v of the alarm.
In most cases, the PE0's readings of local indicatn e will accomplish this.
3.
Take corrective action (s) to r ri.

E01 DGIA GENERATOR TROUBLE This alarm is caused by a generator protective relay actuating.
These relays are located on the panel just to the right of the generator control panel in the diesel generator room.
The relays that can cause the alarm are auxiliary (X) relays actuated by the following primary relays:
132 Reverse power Relay 140 Luss of Excitat. ion 146 Negative phar,e Sequence Relay 151V/A Voltage Restrained Overcurrent (OC) Relays for A Phate 151VfB Voltage Restrained Overcurrent (00) Relays for B Phase 151V/C Voltage Restrained Overcurrent (OC) Relays for C Phase 151N Neutral Ground Overcurrent Relay 159 Cenerator Bus overvoltage Relay 160 potent tal Transformer (PT) Tailure Relay Transformer 164 Cenerator Field Ground Relay 181 Underfrequency 127 Undervoltage on the primary relay for the above functions. a target wi.11 appear showing that the relay has " picked up" when it detects the condition. Jhe diesel generator does not respond in the same manner for all these relays.
The response of each depends on the conditlons under which the diesel generator was started.
i.e..
emergency start or normal start situation.
This can af fect whether the diesel generator cont inues to run or not.
Also, whether the diesel generator output breaker is open or closed can affect how the diesel generator responds to an actuation by certain relays.
Acknowledge the alarm When the alarm is received in the ennti 11 room. the operator should note other associated alarms which mav m nie pertinent information when investigating the cause of the alarm
'n il1 alarms have been noted. the alarm is acknowledged by depressine ' L i hhutton which silences the annunciator horn and changes the -unen

On ofAB. note the phase current. t sie volt age between phases and chite monitor lights kilowatts (X 1.000). KVAR ineter. and frequency (lle ).
Ditect a cAo t o the diesel generator room to determine which relay (8) has been picked up by looking for targeta flags.
The OAO should make note of shat primarv telays and lockout relays have targets showlag, and report his' findings to you.
Take correctiv 3 tions.
Should the generator trouble alarm occur, dispatch an OAO to the generator panel to attempt to locate the difficulty.
This includes checking for d'opped target flags.
Take corrective actions for " generator trouble" alarms by relay numbers as follows:
a.
132 - !<EVERSE p0WER HELAY. The diesel generator output breaker will trip (after a delav upon start) unless corrected.
The diesel generator will have been paralleled.
Observe the KW meter.
If it is very low or zero. increase power.
b.
140 - LOSS OF FIELD EXCITATION. The diesel generator and output breaker will trip when this relay picks up unless the diesel generator was emergency started.
If the diesel generator did not trip. and it is the only available supply to that train's components. closely monitor the operation of that diesel generator and the components supplied by it.
If the 140 relay picked up yet the diesel generator and components continued to operate spuriously, coordinate actions with the SRO.
c.
146 - NEGATIVE PHASE SEQUENCE.
This relay responds to an imbalsace between phases.
After the " generator trouble" alarm occurs, check the voltage and current of each phase of the diesel generator.
If the diesel generator has been normally started and was paralleled, the diesel generator output breaker will open after a time delay.
If the relay picked up due to a blown pT fase, the tripping of the 186C should be blocked due to action of the 160 (pT failure) relay.
If the diesel generator has been emerge 1cy started (LOCA). the relays picking up will still cause the " generator trouble" alarm but will not trip the diesel generator or output breaker, d.
151V/A. 151V/8. 151V/C - PilASE OVERCURRENT RE!.AYS. Any of these relays picking up on a phase overcurrent will trip the output breaker and shut down the diesel generator except on an emergency start.
If one of these relays caused the " generator t rout,le "
alarm when the diesel generator was loaded in an e2iergency start, one or more phases on the phase ammeter would have been observed reading high.
If phase voltages are low. (less than 4160V) and current is high, increasing the voltage will cause the current to decrease as long as the loail (kilowatts) remains the same.

e.
151H - NEtfinAL OVERCL'RRENT RELAY. This alarm will cause the diesel generator to trip and its output breaker to open if the diesel generator has been normally started.
On an emergency start, the relay will cause the " generator trouble" alarm. Once the OAO has found the target on the 151N relay dropped, notify the SRO and initiate an W o. The 151N relay,. when picked up.' has detected a phase-to-ground fault by detecting current returning to the generator via the neut ral ground, f.
160 - PT FA11URE. There are two 4200V to 120V P'fs (three phases each) and their associated primary and secondary fuses on the leads between the generator and its output breaker.
These pts measure voltages used for diesel generator monitoring (meters),
controls (governor), and protective devices (relays).
The 160 relay is normally balanced across the outputs of both sets of pts.
If a PT should fail (or a PT fuse blows), the 160 relay detects the imbalance causes the " generator trouble" alarm, and blocks the tripping of 186B or 1860 when certain relavs pick up due to the PT problems.
This prevents unnecessary tripping of the diesel generator due to blown PT fuses.
If the diesel generator is running and loaded end a PT fuse blows causing the " generator trouble" alarm, observe the status of the diesel generator controls.
The phase ammeter should still indicate normal current.
Check the voltages between phases.
Note the kilowatt meter and KVAR meter.
The indicators will respond differently depending on which PT fuse blew.
If the voltage between any of the phases shows zero and a DGIA LOW VOLTAGE alarm is also present. a blown PT fuse is the usual cause.
Since one of the pts inputs to the exciter regulator and governor. closely monitor the phase current meters.
If operating conditions allow. shut d an the diesel generator. Direct the OAO to observe the 160 relay.
Initiate an MWO to have the pts and fuses checked and conditions corrected.
g, 164 - FIEl.D GROUND. This relay causes the " generator trouble" alarm when a ground is detected by the 164 relay on the generator field. Direct the OAO to observe the 164 relay for indications.
If operational conditions allow, shut down the diesel generator.
Initiate an HWO to have the condition investigated and corrected, h.
159 - Generator bus overvoltage. Ar. overvoltage on the generator bus will cause the generator trouble alarm without tripping the 186B or 186G lockout. In determining that an overvoltage condition caused the generat or t rouble alarm to 'come in, note the voltage for the bus and receive the report from the OAO that the 159 relay is showiue a ilrnpped target. If a higher voltage is noted. lower t he-M voltage to 4160V. Direct the OAO to reset the relay target. M
