Loading Procedure on Advant Controller

AC 160 Advant Controller

A. Single Controller – ON LINE

1. Must be on ON-LINE condition

2. Only to change the parameter, maximum 3 changes

3. Make sure the changing didn’t effect on operation or protection side

4. Step

a. Make change on parameter/variable

b. Save  save and load

B. Single Controller – OFF LINE

1. Create/generate new target code

2. Create new signal

3. OFF-LINE condition

4. Steps;

a. Make change on logic

b. Save then Generate target Code

c. Follow the step on this Target menu (mean while keep open the status report status menu to watch the process);

c.1. Block Program

c.2. Load Application

c.3. Save in PROM 

               

C. Dual Controller – Slave must be Updated

1. Check the connection between master and slave controller
2. To activate the slave  kick out the P1 (master) by force switching

a. Click Reset on P1  b1 will come

b. Acknowledge on b1  P1 will come

c. And the configuration became 

d. Load the controller as usual

e. Reset the P1  bf will come

f. Acknowledge the b1  P1 will come

g. And the configuration will be

h. To update the slave go back to EDS and activate the update slave menu *not necessary since it can be done by hardware updating

i. To update the slave by hardware updating, pres ACK on bf for about 3 seconds until the P.4 comes. 

j. If appear then remove the ACK and bf will be b1 for the next 4 minutes.

The Advanced Pulsation Control Logic (APCL)

A new technogy on logic side to control the Gas Turbine's pulsation concept. Another post will describe the definition on pulsation it self. 

The Advanced Pulsation Control Logic (APCL) is a combustion closed-loop-control-concept for premix operation. The engine’s fuel to air ratio is varied as a function of low range frequency (8-35Hz) RMS pulsation signal to achieve both a required flame stability and a specified NOx emission level, independent of changing boundary conditions such as rapid weather changes or unforeseen variation in fired fuel composition.

The APCL is activated if necessary after Premix/Pilot switch over, normally between 60% and 65% Prel. Activation and deactivation of APCL is done through a ramp to the set points. The ramp generator is used to limit the speed of change of the controller, achieving stable controller behaviour (no oscillating). During transient operation i.e. loading / deloading, the controller parameter are set to faster values to meet the increased requirements.
