Hello everybody.
I just found a document about how to calculate "Maintenance Factor" which mentions:
My questions are about the parameters:
NA = Annual number of part load start/stop cycles (<60% load)
1)Is this mean that if the operator starts the GT and reaches 60% load this counter will increase by 1?
2) If the answer to the first question is yes, What happens to this counter if the operator starts the GT and reaches 60% load and after 10 min selects base load? I mean this is not a start for a 60% load so what happens to this counter?
3) what does Start/Stop means in this definition? is it mean that if the operator stops the GT from 60% load this counter increases by 1?
NB = Annual number of base load start/stop cycles
1) is this means if operator starts the GT and reach to base load this counter increases by 1?
2) If the answer to the fisrt question is yes, what happen to this counter if operator in same start operate the GT for more that 2 days (for instance) in part load and after that select base load? is this base load start or part load start? what haspped to this counter?
3) what does Start/Stop means in this definition? is it mean that if the operator stops the GT from base load load this counter increases by 1?
NP = Annual number of peak load start/stop cycles
1) is this means if operator starts the GT and reach to peak load this counter increases by 1?
2) If the answer to the fisrt question is yes, what happen to this counter if operator in same start operate the GT for more that 2 days (for instance) in part load and after that select peak load? is this peak load start or part load start or base load strart ( because unit has to pass to base load first and after that reach to the peak load. base load start/stop counter increases by 1 during reach to peak load?)
E = Annual number of Emergency start
1) Is "Emergency start" means that start GT to base load in 5 min (I read this from a GE discription that Im not sure about it)?
2) is the rate of "Emergency start" means TNKR1_6 = 8%/min ?
3) what is logic of L83JD6 for this ? we dont have L83JD6 in our logic. can anyone make a example for this logic ( L83JD6) ?
thank you in advance for your attention and help.
