Technical and Economic Aspects of Digital Modeling of Power Plant Facilities

Digital modeling is being introduced into design, management, and research. With the help of a digital model, various scenarios of the object's existence can be played out. Rational technical solutions can be found and tested. In order to determine the optimal parameters of the object, a module for the economic evaluation of technical solutions should be created as part of the digital model. For an power plant facility, three levels of objects of the studied solutions are distinguished: design solutions of the power plant as a whole; system solutions of individual technological systems, buildings and structures; partial technical solutions of individual elements of equipment and structures. At each level, economic methods differ. Various formulations of economic calculations are proposed
