Mathematical simulation in the system of safety monitoring of hydraulic structures and automated control systems of stress-strain state

Introduction. The article describes the features of the systems for monitoring the safety of hydraulic structures, which are based on the apparatus of mathematical and computer modeling. Prospects for the use of automated control systems for the stress-strain state of building structures of hydraulic structures are considered. Materials and methods. An analytical review of foreign examples of the implementation of monitoring systems for high-pressure hydraulic structures based on mathematical models is presented. The results of computational studies of the Zagorsk PSPP complex within the framework of the hardware and software complex for safety monitoring are shown. The concept of automated stress-strain state control systems is described. Results. The advantages and limitations of widely used, domestic and foreign automated information and diagnostic systems are outlined. On specific examples of the integration of numerical models of hydraulic structures into integrated systems for monitoring the safety of hydraulic structures, methods of expanding the capabilities of monitoring systems in terms of analyzing the stress-strain state of structures and predictive estimates are demonstrated. Insufficient elaboration of the issues of management of the stress-strain state of structures is noted, but the need to develop special structural elements with variable parameters to influence the stress-strain state of hydraulic structures is substantiated. Conclusions. The data presented in the article confirm the need to develop systems for monitoring the safety of hydraulic structures based on complex, multiphysics mathematical models, which can significantly expand the functionality of monito­ring systems and, as a result, improve the safety of hydraulic structures. The analysis of world experience indicates the growing lag of the Russian hydropower industry in terms of the integration of mathematical models into the safety monitoring systems for hydraulic structures, which obviously requires additional research and practical work in this area.
