安萨尔多AE64.3A燃气轮机热点保护动作原因分析

Ansaldo AE64.3A Gas Turbine Hot Spot Protection Action Cause Analysis

详细介绍了安萨尔多6F级AE64.3A燃气轮机冷点、热点保护原理。通过某机组调试期间发生的保护动作跳机案例,分析了造成燃气轮机保护动作跳闸的过程,查明IGV自动失灵是造成燃气轮机跳闸的主要原因,为未来同机型重型燃气轮机的安全调试运行提供经验。

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.
