摘　　要：阐述一起PG9171E型燃气轮机的异常振动事件,分析由于进气可调导叶IGV角度偏差造成压气机部分叶片引起旋转失速的内在原因。结果表明:IGV角度偏差对机组安全、稳定运行有着重要影响。An introduction is presented to the abnormal vibration fault in a PG9171E gas turbine, which was found to be caused by the deviation of its inlet guide vane, leading to the rotating stall of partial blades in the compressor. Results show that the angular deviation of inlet guide vane has great influence on safety and stable operation of the unit.
