Ansaldo AE64.3A Gas Turbine Hot Spot Protection Action Cause Analysis
This paper introduces the principle of cold spot and hot spot protection of Ansaldo 6F class AE64.3A gas turbine in detail.Based on the case of protection trip during the commissioning of a unit,the process of gas turbine protection trip was analyzed,and it was found that the inlet guide vane(IGV)automatic failure was the main cause of gas turbine trip,which provides experience for the safe commissioning and operation of the same type heavy-duty gas turbine in the future.
