Abstract
AbstractIn this paper, a rational method has been proposed to determine the maintenance schedule of turbines in thermal power stations. Due to the fact that many failure data do not exist, we focused on the maintenance replacement rate, and the dimensional reduction method was used. The proper maintenance interval based on the future operational rate was chosen by the relationship between the operational rate and the maintenance interval. The results of analysis have shown a reduction in the maintenance cost, while maintaining the current reliability. The proposed method was implemented by Kyushu Electric Power Co. beginning in April 2002 to determine the maintenance schedule of turbines in thermal power stations. Moreover, it can be applied to any other system. © 2003 Wiley Periodicals, Inc. Electr Eng Jpn, 145(1): 10–19, 2003; Published online in Wiley InterScience (www.interscience.wiley.com).
