Dear All,
I could not find any standard for Bypass stack vibration design limits.
Is there any guide or standard you are aware of?
Urgent! Earliest responses much appreciated..
Many thanks

Dear Collegues,
I am planning to purchase one 25 MW and one 45 MW range gas turbines. I am considering GE, Siemens and Solar engines..
We will have daily start-stops and full stop on sundays..I don't like the 'aeroderivative' idea since I have to use a HRSG and a steam turbine so I will not be...
Hi again,
First of all many thanks for the answers they are very helpful.
I forgot to mention that the plant will be 1+1. ( Let's say 43-45+22 MW)
During the turbine inspections it is possible to get energy from the grid and our customer accept the possibilities. But the thing is if anything...
Hi Everybody,
We have a power plant project approx 60-70 MWe. Our priority is having stable and continous energy for a car factory. The factory consumes app. 30 MWe and the lefties will be sold through the distribution grid..
We are considering two different turbines.One of them is a Heavy...
First of all thanks for the responses..
Digitrex you are right. I find out that both of the transformers are step-down..
The parallel work will occur only during transferring ( For maintenance or etc. ) which will last 3 minutes approx...
The other problem is since the load curves are...
We have a 60/80 MVA onan/ Onaf 154 / 34.5 kV Step Up transformer with Dyn1 vector group and 8.22% uk.
Our other transformer will be a 100 MVA onan 154 / 34.5 kV
step up YNd1 8.22% uk.
My problem is the vector groups. I cannot be sure if they can work in parallel. Some says it's ok some says...
Hi,
The capacity of the transformer is generally it's power. For the voltage the general rule is U1xN1=U2xN2 (U stands for voltage and N stands for the wiring) so the voltage you will get from the transformer is according to the voltage you supply it. The thing you should also consider is the...
No load losses can be different.They can be negative too..
The thing should be considered is the total value shouldn't be more than guaranteed factory values.
