Iureva R.A., Vedernikov K.A., Timko A.S., Perezyabov O.A. - Modern wireless technologies: problems of application for modernization of systems for the in-line diagnostics of gas pipelines pp. 68-73

Abstract: Currently, the main method of monitoring of operating gas pipelines laid by the ground, has become in-line diagnostics, carried out by scanning their inner surface. The use of automated cyber-physical systems of non-destructive testing of gas pipelines will increase the level of man-made safety. The article discusses the types of wireless technologies, analyzes the effectiveness of using WFi technology to modernize the process of non-destructive testing of the pipeline in real time. A hypothesis is put forward on the operation of the pipeline as a waveguide for wireless data transmission. To solve this problem, the methods of data transfer theory, graph theory, analytical and simulation modeling are used. The scientific novelty consists in choosing and justifying the choice of using the method of transmitting data from non-destructive testing results over a wireless link in real time based on the analysis of transmitted data and existing technologies, as well as upgrading the design of the cyber-physical system for in-line diagnostics of the gas pipeline laid underground.

Iureva R.A., Kotel'nikov Y.P., Maltseva N.K., Vedernikov K.A. - Study of electric drive used for moving a riding cutoff valve in a turbogenerator control system pp. 7-13

DOI:

Abstract: Proper functioning of a turbogenerator set depends on continuous functioning of the system of regulation and protection of valves of a steam turbine. Proper functioning of a turbogenerator set is important in the case of accident threat caused by the increase of turbine rotation speed over a particular value within the operational range with insensitivity maximum 0,5% of an average operational rotation frequency. The protection of a steam turbogenerator set is guaranteed by cut-out, control and back-flow valves. By a signal of a sensor element of protection, a turbogenerator can be stopped by closing cut-out valves of a high-pressure and an intermediate pressure cylinders or their control valves and a grid valve, or simultaneous closing of the above mentioned cut-out and control units. Such a system operates on the basis of an automated system used for support of the key regulated parameters of a turbogenerator in electric load and heat load modes. The authors of the article study electro-mechanical drive used for moving a riding cutoff valve in a turbogenerator control system. The authors describe the requirements to it. Based on dynamic characteristics of the electro-mechanical drive produced by the joint company “Diakont”, the authors construct a model of a control system, which guarantees the emergency shut-down mode operation. The protection control system structure guarantees the independence of its operation from the condition of a turbogenerator control system.

Iureva R.A., Vedernikov K.A., Andreev Y.S. - Engineering and Technological Solutions in the Process of Developing Robotlike Inspection Systems for Controlling Conduit Pipes pp. 56-63

Abstract: Intratubal diagnostics is part of a set of non-destructive control methods allowing to define internal defects of conduit pipes by the means of technical diagnosis. The main goals of intratubal diagnostics are to define defects in the conduit pipe metal, welded joints, conduit pipe geometry, types of defects, their location and position inside a conduit pipe. To achieve these tasks, a cyber physical system certain requirements set for is usually developed. The present article is devoted to a group of companies 'Diakont', one of the world leaders in the sphere of high technological solutions of security arrangements and increasing efficiency in nuclear, petroleum and thermal power industries. The purpose of the present research is to analyze engineering and technological solutions used in the process of developing a robotlike complex for intratubal diagnostics at 'Diakont' company. The rationale of the research is caused by the growing demand for cyber physical systems related to explosion safety and low cost. Thus, creation of a cyber physical system for controlling conduit pipes is a challenging task. As a result of peculiarities of the environment where intratubal diagnostics are performed, there are strict explosion safety requirements for details and parts of the diagnostic suite. Moreover, the system must have a number of engineering specifics aimed at passing shaped objects, inclined and vertical parts of conduit pipes. The authors' contribution to the topic is their analysis of existing technological solutions made in the process of developing cyber physical systems for controlling conduit pipes.
