The study of cascading failure scenarios in critical infrastructure (power grid) plays an important role in decision-making in such situations, using existing experience to reduce negative conse quences for system components. The modeling and simulation process is complex and requires a large amount of resources, and the volume of data increases rapidly depending on the number of components and connections between them, therefore there is a need to formalize data for further storage, processing and use in analytical models. The article describes the possibilities of using an ontological model to analyze cascading effects in the power grid. The ontological model is used to describe the structure of the network, connections between power grid components and their characteristics at the time of the scenario. The developed model helps the user to formalize information about the operation of the power grid that is understandable to humans and machines. The defined semantic rules are used to verify data and draw logical conclusions, which facilitates the process of understanding the power grid in a given scenario. The defined network structure in the form of a graph facilitates the visual perception of the connections between components, and the description of their characteristics increases the level of detail of the model. The developed model has the ability to integrate with various data sources in the subject area, which are defined using concepts and logical connections between them. The model can be expanded and supplemented with additional concepts and rules according to user requirements. The developed method and ontological model can be integrated with software tools to create a tool for working with data according to the user's needs.
