Risk Analysis and Evaluation of Power Plant Equipment

Abstract:

Because the complexity and The diversity of the fault of large-scale power generation equipment system, it is difficult to carry out the analysis and evaluation for risk of equipment failure definitely and accurately. In the present analysis, most of them are complex function formulas, and not only is it difficult to understand, but also in poor operating in practice. At the same time, it is fail to be divided according to different faults of different devices In the issue of risk classification in the present study, so that the risk classification is not reasonable. This article is based on the research about equipment failure risk assessment, and by risk factors analysis to classify the risk of different failure for different devices. Maintenance mode selection is no longer based on the device but a combination of criticality analysis, and we can propose appropriate maintenance mode in the light of different fault of different equipment.
