Hello everyone,

I’m working on a dynamic centrifugal compressor simulation where the capacity is controlled by inlet guide vanes (IGVs). I’d like to clarify how the IGVs should behave during different shutdown scenarios:

Emergency Shutdown (ESD): My understanding is that IGV position doesn’t change during an ESD, so the simulation should be run with the normal operating IGV position.

Normal Shutdown: In this case, the IGVs can be driven to their minimum position as part of the turndown sequence.


Since I’m new to this type of control, I’d really appreciate any insights or confirmation from those who have dealt with IGV-controlled compressors.

Thanks in advance!
