Modern electric power systems belong to the category of complex power systems, the reliable and safe functioning of which requires a solid assessment of their technical condition. Maintenance of power systems is often implemented on the basis of risk assessment. At the same time, it is difficult to collect basic data, which are mostly of verbal (non-numeric) character. Based on the abovementioned, the article considers the problem of using expert assessments in a risk-oriented maintenance strategy applied to the electric power systems operation process. The paper provides an example of the formalization of information on malfunction occurrence frequency in one of electric power system objects. The article describes a developed software product, which automates the formalization process of fuzzy expert information obtained for risk assessment.
