Description	Fatigue failure of the last three stator rows vanes (S17,EGV1, and EGV2) in the 17 stage gas turbine axial compressor occurred in the power plant whwre low calorific fuel syngas, was used.Causes of this dangerous phenomenon were flow pulsations with the frequencyof 380 - 400 Hz that were found by the experimental investigation of the duty gas turbine. Mechanism of the flow unsteadiness origin was studied with the help of flow simulations in the 2D stator cascade system. Three numerical experiments were carried out. The first experiment investigated the flow simulation in the stator cascade system with a steady undisturbed inlet flow with increased turbulence intensity. Obtained data did not meet the standards of the actual compressor operations. In the remaining two numerical experiments, a purposely designed rotor cascade was located in front of the stator cascades. Shedding of vortex structures from the cascades profile surfaces at positive incidence angles is responsible for the flow pulsation or Fatigue failure of the last three stator rows vanes (S17,EGV1, and EGV2) in the 17 stage gas turbine axial compressor occurred in the power plant whwre low calorific fuel syngas, was used.Causes of this dangerous phenomenon were flow pulsations with the frequencyof 380 - 400 Hz that were found by the experimental investigation of the duty gas turbine.
