摘要
本文通过对M701S(DA)机组压气机喘振裕度低急降负荷事件的调查,对喘振裕度计算逻辑进行了分析,找出影响压气机喘振裕度的因素。从IGV切换时机、喘振裕度保护设定函数的合理性等方面进行了阐述,找出了机组喘振裕度低急降负荷的原因,并从多方面提出了该问题的解决办法,解决了困扰机组急降负荷的问题。
The influenced factor related reason of air compressor surge margin has been developed by investigating M701S（DA） unit air compressor surge margin low fast runback and analyzing control logic of surge margin. According to analysis of several aspects from the exchange point of IGV and surge margin protection function, the reason and solution of this issue are obtained, which successfully solved issue of fast runback.
