Abstract

Abstract: Abstract:Taking the Huadian International Shiliquan Power Plant as example, the function of the small turbine lubrication oil system was introduced. The reasons of the incident of the small turbine shutdown caused by suddenly decreasing of the small turbine lubrication oil pressure were analyzed. The small turbine lubrication oil system was reformed, and the hidden trouble of the suddenly decreasing of the small turbine lubrication oil pressure was eliminated.

Key words: Keywords:300MW unit, small turbine, lubricating oil system, suddenly decreasing of oil pressure, analysis and treatment
