Logical optimization of an alternating auxiliary lubricating oil pump for PG917E gas turbine

Abstract

Abstract:

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.

Key words:
