Abstract
The article considers the issues of assessing professional risks when performing work at electrical substations using mathematical models based on expert assessments. The relevance of developing new approaches to analyzing the probability of hazards in the context of increasing complexity and automation of energy systems has been substantiated. The proposed methodology includes an expert study aimed at identifying and quantifying the factors that affect the probability of hazardous situations. Based on the data obtained, multifactor models have been built to determine the specific weight of each factor and to calculate the final probability of hazard. The practical significance of the developed models lies in their applicability for a reasonable assessment of professional risks, developing preventive measures and improving labor safety. The methodology can be adapted for use in the other industries with an increased level of hazard in industrial activities.
