The purpose of the work is to create methods and tools for mathematical and computer modeling of the processes of functioning of computer-integrated systems as part of power plants for the study and provision of qualitative indicators of the specified class of systems, effective solution of problems of analysis, synthesis and construction of control means taking into account the limited information resources. Research has been conducted and developed: methods of equivalent transformation and mathematical reduction of dynamic mathematical models of power plant regimes in accordance with the limited resources of computer support. A generalized method of equivalent transformation of differential equations into integral and integro-differential equations has been proposed. Within the framework of the general statement of the problem of simplifying mathematical models, a number of partial statements have been formulated, one of which is the “accuracy” parametric reduction of models, which has ensured the development of appropriate algorithms suitable from a computational point of view, namely: algorithms for constructing a domain; algorithms for parametric reduction in the parameter space; algorithms for parametric reduction in the output variable space.
