Accurate risk assessment is an important scientific basis for maintenance decision making. Based on the reliability analysis, prediction technology and fault dialogue technology, this paper defines a risk index, run vulnerability, which considers factors of equipment status, consequences of potential failures and run trend, thus, it reflects equipment risk more comprehensive than that of traditional risk index do. This paper presents a new risk evaluation model based on run vulnerability for power generation equipment. The model process all factors affecting run vulnerability with the quantification of fuzzy rules, and constructs a three-dimensional surface run vulnerability map to achieve the risk assessment of power generation equipment. The example of feed water pump’s risk evaluation validates the model.
