摘　　要：润滑油系统正常与否,直接关系到燃气轮机的安全运行,尤其是解列转速下降后,主油泵逐步退出时,交流辅助润滑油泵能否及时启动,对机组安全运行有着重要意义。机组运行时,遇到调压站工作/备用阀故障关闭打不开时,50%额定转速启动辅助润滑油泵存在一定隐患。优化后,综合考虑了各种可能工况,修改启动逻辑,防止发生发电机烧瓦事故,大大保证了运转设备的安全。The lubricating oil system is normal or not,will directly affect the safe operation of gas turbine.Especially when the main oil pump gradually exits after the splitting revolving speed drops,the timely startup of an alternating auxiliary lubricating oil pump has great significance for the safe operation of unit.When the unit is operating,if an operating or standby valve of regulator station has fault and could not be opened,the startup of auxiliary lubricating oil pump under 50% revolving speed has some hidden troubles.After optimization of modifying the startup logic considering all possible conditions,the tile burning failure of generator is prevented,which ensures the safety of operating equipment.
