Probabilistic Reliability Assessment of Energetic Devices

Popis výsledku v původním jazyce

A key issue for the operators of power plants is to extend the working life of energetic devices and their components beyond the design working life. Currently used procedures are presently focused on the application of common deterministic methods. Thus, it is usually sufficient to use the conservative values of the basic variables for actions and resistance for evaluation of energetic components. On the other hand, it is widely recognized that the input parameters for deterministic assessment may be considered as parameters having stochastic (random) character which can be replaced by statistical distributions in calculations. Deterministic methods should be optimized and potential resources of currently applied procedures identified. Due to a number of influencing factors, the actual state of the energetic device might be difficult to be identified. Probabilistic and statistical approaches can be effectively used to analyze the basic problems in data collection from diagnostic measurements and their subsequent application in estimating the residual life of energetic devices and to optimize processes for their effective maintenance, diagnostics, renovation and also replacement. Data collection and quality assessment can considerably reduce number of failures and can bring major financial benefits for operators. However, this fact is often overlooked, so the main goal of the proposed paper is to present the advantages of the probabilistic approach for assessment the condition of selected devices in the energetic sector in comparison with deterministic methods.
