Use of expert system software for life monitoring of power plant components

Abstract

Life management of primarily high temperature components in power/process plants is a very involved task. Various components in a running power plant are subjected to different loading cycles, temperature, pressure and environmental conditions. The dependence of running power plant on various components as well as interdependence of various components on each other adds to the enormity of the task and requires different maintenance/ repair/ replacement schedules. A systematic and smooth functioning of the plant necessitates a step-by-step analysisfor each components based on its operating parameters, material. In present days, various commercial softwares are used for life monitoring, deciding different schedules in these plants. In the present paper an effort has been made to show the use ofALIAS (Advanced Life Assessment System) and its effectiveness in handling problems related to plant life monitoring, risk analysis, preparing maintenance/repair/replacement schedules.
