WHOLE WEKK 7

CLEAN ENGINE USING ROCHEM

SPECIAL CLEANER FOR ENGINE TO TAKE OF ALL DIRTINIES

the whole week 6

maintenence gt1

pick up vibration detection failed

change with the new

maintenence (the whole week 5)

maaintenence interbus transformer

fill in the insulation oil

my DE3B damaged!!!!!

we off the breaker in 11 kv switchgear room

than check any possible that causes DE3B failed

from the inspection, the avr card was failure

3rd WEEK(Ist DAY)

today, we fixed gt2.

this are the step taken by us:

• We open the breaker in 11 kv room, then we check the turbine generator circuit breaker,it was in a good condition
  
  · We check the fuse F1,20A,DC and we figure out it was in good condition.Then we check the relay K84(RELAY CIRCUIT BREAKER CLOSE) and K85(RELAY CIRCUIT BREAKER TRIP & CLOSE ENABLE), CBCS( circuit breaker control switch),K114(RELAY DSM GEN SENSE ENABLE), PT(POWER TRANSFORMER)
  

FIGURE 1:POWER TRANSFORMER

FIGURE 2:GENERATOR CIRCUIT BREAKER 52G

· Check the supply power VDC
· OFF the breaker in transformer panel
GREEN-CLOSE BREAKER”ON”
RED-OPEN”OFF”
· Open AUX TRANSFORMER FUSED SWITCH
· Charged the battery breaker(52G)
· Unfortunately we failed to synchronize the relay after we switch on
· We change 2 new relay for K28(RELAY GTG SYNC ENABLE) and K5

FIGURE 3: RELAY

· We test “ON” but still failed
· We shut down again and check fuse at GENERATOR CURRENT BREAKER CUBICLE,(OK)
FIGURE 4:CHECK FUSE
· From PLC, check TB-B-K27-14 AND TB-B-K27-11(OK)


OVERTIME
· Check forwarding fuel pump lamp no 1 & 2
· Check supply from PLC, if K27 not function means K85 also not function (OK),
· TEST RUN at the synch breaker control “failed”


· Check back K114,25Aand B,7K10,6K10 AND it was “ ok”
· We figure out the problem was actually cause by untight wire at K1(RELAY POSITIVE SHUT DOWN MASTER). After we tight back the wire properly and tested on ,the GT2 start running. GT2 ON AT 11.45

2nd WEEK (4TH DAY)

i'm wif MAT Replace back motor at GT1(Gas Turbine) to storage tank because the original motor for GT1 was already fixed. the motor is less horsepower than the motor at storage tank(3Hp). da problem we faced at dat time we are running out a suitable connector BUT dat's a small matter for MAT because his so expert in this field.. and we coorperate wif mechanical college to help us by winding the box for motor place. lastly we need to make sure the motor running clockwise rotation otherwise the oil that should be send to the engine transmit back to the storage tank...huhuhuh

"CAN U FIGURE OUT WAT WOULD BE HAPPEN IF DIS SITUATION OCCUR????"HUHUH

then in da afternoon i'm doing my research in DA control room

SECOND WEEK(3RD DAY)

today i'm wake up in the early morning coz i wanna to learn how to start engine 3B(DG6B) wat a fantastic moment!!!!! it's about 7.15 am i went to control room to see the real demonstration from uncle ALADDIN. There is are step to start up the big engine(DG6B):

1. raised "Governor Speed Low/Raised"(GS L/R) button until 500 rpm




2. then ON (Auto Voltage Regulator-AVR) then raised untill exceed 11kv
   



3. ON synchronizing and make sure its clockwise rotation and stop it between 12. this situation means the engine already synchronize with other engine




4. raised speed( GS L/R) until the POWER 3MW(for the first reading)




5. lastly set AVR until the PF=O.95
   
   FOLLOW the step(1-5) for other engines

around 9 am i'm with electrical gangs participate BOMBA TALK, THEN MKN FREE HAHAHAH, we also practise fire drill and participate the competition that held by them. our departments won the game.HOORAYYYY~~~~~!!!!

we need to running as fast AS FURIOUS to turn off the fire
