5.0 ALARM SEQUENCES

5.1 WARNING

The purpose of the warning sequence is to inform the operator of events.

5.2 DG BLOCK

The DG block alarm sequence is used for blocking of any further automatic functions which will

lead to connection of the generator set to busbar.

5.3 SAFETY STOP

The safety stop sequence is used to carry out a previous intervention and stop a defective engine,

Instead of waiting until a critical condition becomes fatal for the engine.

Safety stop sequence also can prevent a possible black-out situation at the busbar as it replace the

defective generator set before a shut down occurs on a running generator set.

Safety stop sequence starts and connects the next standby generator set to the busbar according to

chosen start/stop priority. When sufficient available power is measured at the busbar generator

set is disconnected and stopped (inc. cooldown etc.). As long as a critical failure signal is

received the defective DG will be blocked.

5.4 SG BLOCK

The SG block alarm sequence is used for blocking of any further automatic functions which will

lead to connection of the shaft generator set to busbar.

5.5 SG&BT BLOCK

The SG&BT BLOCK alarm blocks the SG&BT operation until the alarm is reset by the operator.

26

5.6 ALARM RESET

Alarm resets are grouped under 6 reset options in the PMS software. When the RESET button is

touched PMS controller will reset the related alarm and the actions taken by the controller.

• Reset of SG alarms

• Reset of DG alarms

• Reset of SG PPU alarms

• Reset of DG PPU alarms

• Reset of TRANSFER alarms

• Reset of BT1 alarms

ALARM RESET button(s) will reset only the active alarms which are red highlighted by the

operators touch. Alarms registered by the MULTIMATIC PREMIUM PMS should be reset in

order to reset the action(s) taken by the PMS controller. Alarms that still keep the alarm condition

will not be rest! Those alarms can only be acknowledged.

Alarm reset popup window will automatically appear when de desired alarm is touched on RESET button will reset the alarm and the actions taken by the controller.

8.0 PLANT MODES

The MULTIMATIC PREMIUM PMS Multi function system operates according to the

functionalism of the selected plant mode.

The plant modes are automatic functions according to the functionalism of the selected mode.

This means every function may not be carried out in every mode.

The system is able to handle the fallowing plant modes:

• AUTOMATIC MODE

• SECURED MODE

• SHAFT GENERATOR MODE

The selection of the plant mode for the entire power plant is done by the buttons located on the

PMS mimic page of the CP.

Red button indicates that the mode is not available. Yellow button indicates that the mode is ready. Green button indicates that the mode is running. Blue flashing button indicates that the mode is selected but in still progress.

9.0 OPERATING PRINCIPLES OF PLANT MODES

9.1 AUTO plant mode

During this full-automatic mode, called AUTO mode, the PMS control is carried out by all

generator sets which are under PMS and REMOTE control.

Load depending start and stop function of the generator sets are carried out according to the

actual power demand at the busbar with respect to; the programmed start/stop priority and the

programmed limits for start and stop.

The load depending start/stop function take any running generator set which fail during

engagement in consideration, by starting up the next standby generator set and substitute the

defective one.

If the system detects a black-out situation, a conditional black-out start of two generator sets is

carried out.

9.2 SECURED plant mode

The SECURED plant mode is almost the same as the AUTO MODE.

When the SECURED mode is selected automatically the largest connected generator sets

nominal load is taken in to consideration and the Load depending start stop limit is increase by

the nominal load of the largest connected generator set.

This means that the nominal load of the largest connected set is available at the busbar at any

time during SECURED mode.

The SECURED plant mode prevents a blackout situation ay be caused by a sudden cut out of a

generator set from the busbar.

35

9.3 SHAFT GENERATOR mode (SG mode)

Selection of SG plant mode is only accepted by the PMS controller if:

• All running generator sets are ready for PMS stop

• The shaft generator is able to substitute the total power produced by the running diesel

generators

• If the system is receiving constant speed signal

And the plant mode is either SECURED or AUTO mode.

At once the SG mode is selected system automatically sends excitation signals to shaft alternator

and end examines the generators voltage when the shaft generators voltage is ok, the

synchronization of the diesel generator set(s) to shaft generator takes place.

The SG plant mode is automatically cancelled if:

• A failure occurs during the engagement of shaft generator.

During an active SG plant mode conditional connection of heavy consumers are allowed as long

as the shaft generator is able to handle the predicted power demand at the busbar.

An ongoing SG plant mode is automatically cancelled if:

• Black-out is detected

• When the operator selects AUTO or SECURED mode

• When the SG&BT operation is selected

*** During the SG mode the nominal load of the shaft generator is continuously examined and

when the shaft generator power exceeds the total nominal power of the PMS ready generator sets

Selection of AUTO, SECURED and SG&BT modes are blocked.

10.0 LOAD DEPENDENT START/STOP FUNCTION

The load dependent start/stop function is active when AUTO or SECURED mode is selected and

the shore connection breaker is not closed and the tie breaker is closed.

The start/stop function transmits PMS start and stop commands, which are based on a calculation

of how many generator sets are needed in order to satisfy the actual power demand at the busbar.

The PMS start/stop commands are sent to individual generator set according to the selected

start/stop priority.

Transmission of the Load depending PMS start/stop commands are based on the comparison of

the programmed start/stop limits and a special M-PREMIUM value PAP (predicted available

power).

37

10.1 PAP (Predicted available power)

In order to ensure sufficient available power at the busbar at all times, the M-PREMIUM system

use a value called predicted available power (PAP).

0

100

200

300

400

500

600

DG1 DG2 DG3

P-NOMINAL(kW)P-CONSUMED(kW)

Calculation of the PAP is based on the summation of the available power at each running

generator set the result is the total measure available power at the busbar.

The predicted available power is calculated with the consideration of the following events.

• The extra available power at the busbar during SECURED plant mode.

• The nominal load of a generator set which is about to be stopped due to a safety stop

alarm sequence (expected stop)

• Conditional connection of heavy consumers

PAP: predicted available power

MAP: measured available power

SPM: secured plant mode (nominal load of the highest connected generator)

SS: safety stop (nominal load of the generator expected to be stopped)

HCN: heavy consumer’s nominal load

HCA: heavy consumer’s actual load

PFstop: nominal power of the DG to be stopped first

38

PAP=MAP – SPM – SS - (HCN - HCA)

PAP= 600 kW – 0 kW – 0 kW – (300 kW– 0kW)

PAP= 300 kW

*** Example represents calculation of the PAP in case of heavy consumer start

10.1.1 Programming of the load dependent start limit

Generation of the load dependent PMS start command is based on a comparison of the PAP at the

busbar and the programmed start limit (LOAD START LIMIT) in the system.

Start command is transmitted to next standby generator time delayed if PAP < LOAD START

LIMIT in order avoid unnecessary start of a generator set.

*** Delay is time equals to the programmed timer value as LOAD DEPENDENT STAR

DELAY.

10.1.2 Programming the load dependent stop limit

The PMS stop command is generated by comparing the programmed stop limit value with the

result of the following calculation; PAP is deduced with the nominal load of the generator set

designated with the highest stop priority.

PFstop: nominal power of the DG to be stopped first

PAPs = PAP – PFstop PAPs = 300 kW– 600 kW

PAPs = -300 Kw

Programmable stop limit represents the desired remaining available power at the busbar after load

depending PMS stop of the generator is carried out.

39

Therefore system uses PAPs calculated value with the LOAD DEPENDENT STOP LIMT and

decides whether to send a PMS stop command or not.

Stop command is transmitted to next standby generator time delayed if PAPs > LOAD STOP

LIMIT in order avoid unnecessary start of a generator set.

*** Delay is time equals to the programmed timer value as LOAD DEPENDENT STOP

DELAY.

40

10.2 SELECTION OF START/STOP PRIORITY

The load depending start/stop function uses the programmed priority information when the start

stop commands are to be transmitted.

NOTE: the start/stop priority keeps account with which diesel generators are ready for PMS start

and which are ready for PMS stop. Any generator set which, during operation becomes not ready

are not accepted as the next generator to be started or stopped.

10.2.1 Setting of the start/stop priority

Manual designation of the desired priority:

*** Programming and read out of the start/stop priority is from the CP.

The M-PREMIUM system will not except two or more generator sets to be programmed with the

same start/stop priority or other than 1,2 and 3. Refer to the figure below. Wrong selection

indication will appear when the system refuses the setting.

Wrong selection indication blocks for priority setting.

41

Automatic designation of the desired priority:

This function ensures the operating hours are equally distributed at all generator sets in the power

plan

M-PREMIUM system counts and logs the operating hours of the generator sets and when desired

the start/stop priority is designed according to the operating hours of the generators.

This is done by the following steps:

1. press the AUTO PRIORITY button

2. Press SET PRIORITY button

e.g. The start priority before the automatic designation is

P1=1 dg1 TOTAL RUN HOURS=12340 ***

P2=2 dg2 TOTAL RUN HOURS=12320 *

P3=3 dg3 TOTAL RUN HOURS=12330 **

The start priority after the automatic designation is

P1=2 dg1 TOTAL RUN HOURS=12320 ***

P2=3 dg3 TOTAL RUN HOURS=12330 **

P3=1 dg1 TOTAL RUN HOURS=12340 *

-After pressing the AUTO PRIO button the indication ‘AUTO PRIORTY IS SELECTED SET IN 15 s’ appears -Operator has 15b seconds to set the designed priority -If it is not set in 15 seconds priority will be left with the previous setting

42

10.3 DETERMINATION OF START PRIORITY

The PMS controller designates each generator set with a PMS start priority number according to

the programmed Priority sequence.

P1= 2 dg2 to be started first

P2= 1 dg1 to be started second

P3= 3 dg3 to be started last

10.4 DETERMINATION OF STOP PRIORITY

The PMS controller designates each generator set with a PMS stop priority number according to

the programmed Priority sequence.

P1= 2 dg2 to be stopped last

P2= 1 dg1 to be stopped second

P3= 3 dg3 to be stopped first

43

11.0 BLACK-OUT FUNCTION

The black-out function is active when ever the following plant modes are selected

• AUTO mode

• SECURED mode

• SG mode

Detection of dead busbar status activates the black-out start sequence.

*** A short circuit alarm at any DG will block the entire black-out function

11.1 The black-out start sequence

Activation of black out sequence is only available if;

• There is no short circuit alarm from and circuit breaker

• All circuit breakers are in OFF position

• At least one of the DG are in PMS control

NOTE: A synchronization alarm is automatically acknowledged (reset) in case of an active dead

busbar status. But not the start failure alarms.

The black-out start sequence carries out the following step by step

a) A PMS start command is transmitted to DG’s with the highest and second start priorities,

which at the same time ready for PMS start.

b) A CB ON/SYNCRONIZE command is immediately transferred to the PPU of the first

running DG

*** if this does result in the closing of the generator breaker the other Black-out started

generator will be requested to close its breaker after 2 seconds delay.

c) A CB ON/SYNCRONIZE command is transmitted to the second black out started

generator’s PPU will be requested to close its breaker after 2 seconds delay.

d) If any of the two chosen generator sets fails during the start sequence the PMS start

command is transferred to the next standby generator as long as the black-out situation is

present.

e) When one generator sets is successfully connected to busbar approx. after 2 seconds the

black out situation is considered to be completed.

45

12.0 CONDITIONAL CONNECTION OF HEAVY CONSUMERS

M-PREMIUM PMS system is able to handle 5 conditional connection of heavy consumers

(HC’s)

When requested by a heavy consumer, function for conditional connection of heavy consumers

reserves the programmed max. Power at the busbar and block for engagement of the heavy

consumer until sufficient predicted power is present at the busbar.

If PAP > LOAD START LIMIT (HC) is acknowledged.

Acknowledge signal is set with delay in order to let the recently started generator set(s) to take

load and thus actually increasing the available power at the busbar before engagement of the HC.

The heavy consumers are acknowledged according to their priority.

If two or more heavy consumers requests for start acknowledgement at the same time the HC

with the highest priority is handled first, subsequently with lower and etc.

HC1 is designated the highest priority in the M-PREMIUM system, HC 1 is handled before HC 2

HC 3 and HC 4 and so on.

NOTE: If there are any preferential Heavy consumers they should be connected to M-PREMIUM

system in the order 1,2,3,4 and 5 in order to ensure right the priority.

The M-PREMIUM system carryout the following step by step sequence, when a HC request for

start acknowledgement:

a) The programmed “HC n MAX POWER” value is reserved at the busbar.

b) A PMS start command is transmitted to the next stand by generator set if PAP is below

the programmed “LOAD START LIMIT”.

c) When sufficient predicted available power is present at the busbar. The timer

“HCn_ACKN.DELAY” starts running.

46

d) When the timer “HCn_ACKN.DELAY” runs out acknowledge signal is transmitted to the

HC in request.

The M-PREMIUM system uses analog power feed back.

• 0..10 VDC

• 0..20 mA

• 4..20 mA

47

12.1 Start of heavy consumer with analog power feedback

Start of a specific heavy consumer with variable load (HCn) is made by activating the

corresponding start request input.

*** The start request signal must remain activated for as long as the HC are to be operation.

Power reservation ends when the start request signal disappears.

The acknowledge signals duration is 3 s.

In order to prevent overload at busbar during the operation of HC, the actual power consumed by

the HC (measured by analog feedback) is taken in to consideration. The reserved power at the

busbar for this HC is reduced (from maximum power) with actually consumed power. This

calculation is continuously made in order to optimize the reserved power at busbar.

18.0 SHAFT GENERATOR CONTROL AND SUPERVISION

The shaft generator control consists of a number of automatic sequences. These automatic

functions altogether form a complete cycle of operation for the shaft generator.

The shat generator is activated by means of the SG plant mode

Selection and cancellation of the SG plant mode is able to respectively initiate and complete the

cycle of operation for the SG.

Selected SG plant mode is automatically cancelled and auto mode is selected if a failure occurs

during the engagement of the SG, or a blackout occurs at the busbar.

e.g. SG voltage is not in expectable limits, PPU is unable to complete SGB on sequence.

• Selection of SG plant mode

• SGB ON sequence:

-load transfer from diesel generators to shaft generator

• Load supervision during operation

• Selection of Auto plant mode

-Automatic start of the stand-by generators

• SGB OFF sequence

-De-loading of the shaft generator / load transfer from the shaft generator to diesel

generators.

18.1.1 Load transfer from DG’s to SG

Once the shaft generators breaker is successfully synchronized and cut-in at the busbar, the load

transfer from the running diesel generator sets to shaft generator is initiated.

This is done by sending GB OFF/DELOAD commands to all running generator set’s PPU’s.

*** Diesel generator set de-loading is carried out by the PPU of the DG set.

NOTE: if a failure such as “DGB OFF FAIL” occurs during the load transfer of any running

generator sets, the SG plant mode is cancelled and the AUTO plant mode is automatically

selected again.

18.2 LOAD SUPERVISION DURING SG PLANT MODE

The load depending start stop function is disabled when the SG plant mode is selected.

Calculation of the PAP is continuously carried out as a hidden function. And during an ongoing

SG plant mode supervision of predicted available power PAP is also active.

The conditional connection of heavy consumers is also available in SG plant mode like in Auto

or Secured plant modes.

If the calculated PAP becomes below 0 kW when any of the heavy consumers requests for start

the start is denied acknowledge signal is not transmitted.

65

18.3 SGB OFF SEQUENCE

The automatic SGB OFF sequence is initiated, if one of the blow mentioned events occurs:

• The operator selects AUTO or SECURED plant mode

• The SG&BT operation is selected by the operator

Or

• The SG plant mode is cancelled automatically by the M-premium system when the

constant speed signal is lost, slowdown signal is received or the SG bus voltage is below

the acceptable limits.

If any of the above mentioned event occurs M-premium automatically calculates the power

needed to substitute the actual real power produced by the shaft generator and sends PMS start

commands to the DG’s which has the total nominal power in order to substitute the SG.

18.3.1 Synchronization of DG’s to the shaft generator

The started diesel generator sets synchronize and connect to the busbar as GB ON sequence.

If a “GB ON FAIL” alarm is active during the load transfer SG plant mode is automatically

selected again and PMS stop command are sent to running DG sets.

18.3.2 De-loading of the shaft generator – load transfer to DG’s

The automatic SGB OFF sequence sends SGB OFF/DELOAD command the SG’s PPU and the

PPU de-loads the SG by ramping up the real power generated by the diesel generators before

opening the SGB.

NOTE: if a failure occurs during the SGB OFF sequence such as SGB OFF failure SG plant

mode is automatically selected and the PMS stop command are sent to all running DG sets.

19.0 SG&BT CONTROL AND SUPERVISION

The SG&BT control consists of a number of automatic sequences. These automatic functions

altogether form a complete cycle of operation for SG&BT

The SG&BT operation is activated by the operator directly from the control panel or with an

external request input from the wheelhouse.

Selection and cancellation of the SG&BT operation is able to respectively initiate and complete

the cycle of operation for the SG and the DG sets

Selected SG&BT operation is automatically cancelled if a failure occurs during the SG&BT

operation sequence.

e.g. SG voltage is not in expectable limits or “BT1 IN FAIL” is active

PTI mode is almost like AUTO mode.

• Load dependent start/stop functions are available for this mode.

• Conditional connections of heavy consumers are also available if the predicted available

power is above the programmed limit.

When an external PTI mode request signal is received and if the SG is ready for PTI, PMS

controller immediately sends PMS start commands to the DGs.

Number of DG’s to be started and reserved for PTI mode is set under the window GENERAL

SYTEM CONFIGURATION.

In PTI mode the reserved DG sets are not included in the load dependent start/stop function but

the remaining DG set which are PMS start ready are included in load dependent start/stop

function. This means that during an on going PTI mode the programmed number of DGs in PTI

mode will be connected to the busbar and reserved for PTI at any time until the mode is

cancelled.

21.0 SUPERVISION OF THE SHORE CONNECTION

The PMS controller supervises the position of the shore connection breaker.

Once the ON status at the shore connection breaker is detected all automatic sequences for start

of the auxiliary engines are blocked.

• Load dependent start is blocked

• Blackout function is blocked

21.1 SWITCH OVER TO THE SHORE SUPPLY AND BACK

Following sequences are the possible suggestions on how to handle the switch over from dieasel

generator supply to shore supply and back.

21.1.1 Switching to shore supply from generator set supply

The operator may use the below described step by step procedure, when switching over from

diesel generator supply to the shore supply.

• Select SWBD control on all DG sets (both running and stand-by generators)

• Open all generator breakers via the switch board control

*** This will create a black-out situation but as long as all the DG sets are in SWBD

control blackout start sequence will not start and blackout start commands will not be set

to the DGs.

• Now turn the shore connection circuit breaker to ON position

*** The ON position of the shore connection breaker blocks for blackout start of the

generator sets.

• Select PMS control on all DGs again.

71

21.1.2 Switching from shore supply to generator set supply

The operator may use the below described step by step procedure, when switching over from

shore supply to generator supply.

1st scenario:

• Select PMS control on all DGs corresponding to generator sets which are desired to be

included PMS control.

• Turn the shore circuit breaker in to OFF position; this allows black0out start of the

generator sets

• When the black-out start sequence is completed normal automatic PMS control functions

are re established

2nd scenario:

• Select SWBD control on all DG sets

• Manually start the first two of the generator set according to the priority programmed

from the PMS controller side

*** Don’t close the breakers of the DG sets

• Select PMS control on all DGs or at least the running ones corresponding to generator

sets which are desired to be included PMS control.

• Turn the shore circuit breaker in to OFF position; this allows black0out start of the

generator sets

• When the black-out start sequence is completed normal automatic PMS control functions

are re established

72

3rd scenario:

• Select SWBD control on all DG sets

• Manually start the number of desired generator set(s) according to the priority

programmed from the PMS controller side

• Manually connect the DG set to the busbar

*** Blackout situation is disappears

• Select PMS control on all DGs or at least the running ones corresponding to generator

sets which are desired to be included PMS control.

• Turn the shore circuit breaker in to OFF position

• If not selected select the AUTO or SECURED mode from the control panel

73
