In this paper, a reasonable method has been proposed to determine the maintenance schedule of turbine in thermal power stations. Due to a fact that many failure data do not exist, we paid attention to the maintenance replacement rate, and the dimensional reduction method was used. Proper maintenance interval based on future operation rate was decided by the relationship between operation rate and maintenance interval. The results of analysis can reduce the maintenance cost, meanwhile keeping current reliability. The proposed method will be adopted by Kyushu Electric Power Co. from April in 2002 to determine the maintenance schedule of turbine in thermal power stations. Moreover, it can be also applied for any other systems.
