The first link has a picture of some of these vanes: first column, second row.
VIGVs direct air into the first rotor stage. They have the effect of improving the difference between the mass flows at operating points in the mid-range and corresponding surge points (which are catastrophic points at which flow through the stage could spontaneously reverse). Please see the second link and third.

governor has 3 modes of operation 1.SPEED CONTROL MODE-before sychronisation the governor runs in speed control mode.guide vanes open up and the turbine runs in the rated speed.when the governor gets connected to the grid that is when it gets synchronised then the speed control mode terminates. 2.OPENING MODE-load is increased in this mode and teh machine runs in the rated speed only. 3.POWER CONTROL MODE-it has two modes.joint controller and indivisual controller mode.in joint controller mode all the machine works all together and in the indivisual controller one setup point is given to the governor and the guide vanes vary accordingly
Variable inlet guide vanes are typically found in axial compressors and turbines. They operate by adjusting the angle of the guide vanes to control the flow of air or gas entering the compressor or turbine. By changing the angle of the guide vanes, the system can optimize performance by altering the velocity and direction of the incoming fluid flow.

Variable inlet guide vanes (VIGV) are typically used in satellite compressors to allow for capacity variation. These vanes can control the airflow entering the compressor, thus adjusting the compressor's capacity.
In axial flow compressors, the primary purpose of IGVs (fixed or variable) is to guide the airflow onto the first stage rotor blades at an appropriate or required angle of attack.
Capacity control in large centrifugal refrigerant compressors is typically achieved through methods such as variable inlet guide vanes, variable speed drives, and slide valves. These methods help adjust the flow of refrigerant into the compressor to modulate its capacity based on changing system requirements.

You should consult the control.com website, they have a plethora of information and instructions on how to manually callibrate the IGV of a gas turbine.

By making it vanes variable direction so that it can work from both side.
Stay vanes are stationary vanes located at the entrance of a turbine or pump to guide the flow of fluid towards the rotating blades. They help control the direction and speed of the fluid entering the machine. Stay vanes work in conjunction with the rotating blades to efficiently convert fluid energy into mechanical energy.
stall happen due to too much suction feed but less discharge and will prevent by implemented inlet guide vanes, surge happen due to less suction feed at operating speed and will prevent by intalling recycle line or anti surge line.
