摘　　要：喘振故障是燃气轮机发电机组常见的故障之一,喘振对燃机的正常工作带来了极大的影响,并对燃机本体的寿命产生严重的威胁。本文通过对燃气轮机发电机组压气机的喘振故障的机理及原因进行了详细的分析,介绍了压气机喘振时的主要表现特征。基于对压气机喘振产生的原因的分析,总结提出了压气机喘振故障诊断的依据和喘振故障的解决措施,为燃气轮机发电机组安全运行提供技术参考与借鉴。Surge fault is one of the common fauh in the gas turbine generator units. Surge brings greatly affect to the normal work of the gas turbine generator units ,and have a serious threat to the life of the gas turbine generator units. This paper has analyzed the reason and mechanization of the compressor surge of the gas turbine generator units, and introduced the main performance characteristics when the compressor surgeing. Based on the analysis of causes of compressor surge, this paper proposes the basis for surge fault of the gas turbine and measures for the prevention of the surge fault, providing technical references for the safe operation of the units.
