摘要: In a method of operating a gas turbine during shut down, the gas turbine is decelerated and closure of compressor inlet guide vanes (1) is initiated at a shaft speed at least 5% above the shaft speed where a vibration peak occurs. The compressor inlet guide vanes (1) are closed by an angle in the range from 15°-35°, preferably at a rate between 5° and 10° per second. The method effects a reduction of the risk of rotational stall.
