中文摘要: M701F4燃气轮机在发电机组运行中出现#2燃烧器叶片通道温度偏差大报警。本文针对该报警事件原因进行分析，发现采用雷达图进行数据分析具有更强的可观性，能够更好地体现BPT偏差数据动态变化， 通过数据变化分析故障原因，缩小故障范围，指导故障处理，最终确认燃烧器V型滤网堵塞是产生此次报警事件的根本原因。
Abstract:Blade path temperature deviation alarm of #2 combustor appeared in the operation of M701F4 gas turbine.To analyze the cause of alarm event，we found that radar data analysis had a stronger observability and it can better reflect the dynamic change of BPT deviation data. Based on analyzing the cause of failure through the data changes，and reducing the fault coverage and guiding the fault processing，it was finally confirmed that the combustor V filter blocking was the root cause of this alarm event.
