After studying the CSRGVPS algorithm of a 5002B heavy duty gas turbine, I found that the inlet guide vanes are automatically positioned closed during a start-up and a shutdown sequence to avoid gas turbine compressor pulsation or combustion pulsation. I found also to protect the axial compressor from the rotating stall region at low speed.
Can any one please explain to me what does this mean exactly (physically)!
What can happen to the compressor exactly?
Thanks in advance.
