摘要:

针对PG9171E型燃气轮机非正常停机过程中发生交流润滑油泵(88QA)无法正常投运引起机组润滑油压力降低并跳闸的现象,对交流润滑油泵控制逻辑进行分析,并提出了优化控制逻辑的措施,以保证机组安全运行。

Abstract:

The AC lubricating oil pumps (88QA) cannot be put into operation normally during the abnormal shutdown of the PG9171E gas turbines, which causes the low lubricating oil pressure and tripping. Through the analysis on the control logic of the AC lubricating oil pump, measures to optimize the control logic are proposed to ensure the safety of the unit.
