Abstract
The article attempts to substantiate a new direction of scientific research of pipeline systems (PLS) of the energy sector as cyber-physical objects. The relevance of this direction is determined by the practical formation of new properties of PLSs in the process of their renovation, intellectualization and digitalization, along with the absence of a general theory of classification of the goals pursued, emerging problems and solution methods. It is proposed to base such studies on the theory of hydraulic circuits, the subject of which is the general methods of mathematical modelling, calculation and optimization, applicable in principle for any PLS (heat, water, oil and gas supply, etc.). The concepts of controlled and cybernetic hydraulic circuit are introduced as a new object of study of this theory. The content of new classes of problems of research and modelling of hydraulic circuits as cybernetic is revealed. The characteristics of the available results in the field of methods of analysis and synthesis of PLSs as cyber-physical objects are given. Mathematical models and methods of analysis of the consequences of regime control in conditions of stochastic of external influences and uncertainty of the internal state are presented. A set of indicators for the integral assessment of the controllability of the PLS is proposed, reflecting the main aspects of management: admissibility, reliability and efficiency. Integral indices of PLS identifiability and methods of their calculation are proposed. The interrelation of these indicators, which can be used to develop methods of analysis, synthesis, norms and standards of controllability and identifiability, as the main cybernetic properties of PLS, is disclosed.
Highlights
The modern scientific and technical situation in Russia is characterized by the processes of transition to a new economic order, combined with the transition to a new technological order in the world
An attempt is made to systematize a new problematic – the theory of hydraulic circuits associated with the mathematical modeling of pipeline energy systems (PLS) as cyber-physical systems, in order to obtain results that are of general importance for PLS of various types
Adaptive feedback control is understood as the ability to adapt the models involved to changes in the internal state of the PLS and external influences based on the observation and measurement of the parameters of the state and manifestations of the external environment
Summary
The modern scientific and technical situation in Russia is characterized by the processes of transition to a new economic order, combined with the transition to a new technological order in the world This creates unique challenges that present new requirements for technical policy and scientific and methodological support of the tasks of innovative transformation of pipeline energy systems (PLS) heat, water, gas, oil supply, etc., which are playing an ever-increasing role in energy, industry, social sphere and economy most industrialized countries. The main direction of overcoming these challenges in the country and abroad is associated with the digitalization and intellectualization of the PLS [1] In technical terms, these trends are manifested in the combination of the unique capabilities of modern equipment, telecommunications and information technologies in real control loops of the PLS. An attempt is made to systematize a new problematic (formulated and developed in the ISEM SB RAS of the original scientific direction) – the theory of hydraulic circuits associated with the mathematical modeling of PLS as cyber-physical systems, in order to obtain results that are of general importance for PLS of various types
