摘要
针对某三菱M701DA燃机首次启动过程中燃烧不稳、转速偏差大的异常现象,在分析控制原理的基础上,介绍了现场的分析过程,确定燃机流量控制阀差压变送器阻尼系数设定不合理的问题,并给出新的设定值,现场运行表明新的设定值能避免启动过程中这些异常现象的发生。
Focusing on the abnormal issues including unsteady combustion and overlarge speed deviation of the M701DA gas turbine during the first starting procedure, this work firstly introduces the whole analysis process, and then, determines that the unreasonable setting of damping coefficient of the differential pressure transmitter is the main reason for these issues. By using new setting values, it is found that the abnormal issues are effectively avoided.
