When implementing development concepts in the electric power industry (such as “Smart Grid”, “Digital substation” and “Outsourcing of services”), the task of ensuring stable relay protection operations and automation devices is urgent. The problem is solved according to the developed structural-information (SI) method. A method for selective search of the optimal amount of structured information for automatic decision-making is proposed. The article discusses an algorithm for recognising scenarios for the development of semantic events, which is included in the SP-method. The algorithm is applied uniformly for all hierarchical levels of recognition, based on the goals of decision making at the senior level. Control of the sequence of information events is performed in the dynamics of the passage of events along one path from all relationships according to the structural-information model. Part 1 shows a collaborative structural-information model consisting of a shaping tree in a dynamic object and a recognition tree in devices. A theoretical description of the algorithm is given using the amplitude and time (Ξ,Η) selectivity windows in the general structural scheme of S-detection. The application of the method for different hierarchical levels of recognition is shown. The decision-making results are presented in two forms, by means of a single semantic signal to indicate a group of results and filling in the table of the sequence of occurrence of the recognised elementary information components. Part 2 shows the application of the SPmethod at different hierarchical levels of recognition for the synthesis of a selective relay, which implements an algorithm for finding a damaged network section with single-phase ground faults in 6-35 kV distribution networks with a Petersen’s coil. The reasons for the unstable operation of algorithms of known selective relays are indicated, based on the concepts of scenario recognition. The improvement of the structure of a selective relay operating on the basis of the criterion for monitoring the coincidence of the first half-waves of the mid-frequency components in the signals of transient processes is considered. Examples of the synthesis of elementary detectors of absolute, relative and cumulative actions in relation to a selective relay are given, which make it possible to fill the amount of information for general S-detection. The simulation of the operation of the synthesised S-detector on the signals of real emergency files of the natural development of damage to the isolation of the network phase and simulation of artificial scenarios of events in the mathematical SI-model are carried out.

“…An alternative device that provides a reasonable compromise between the implementation of the functions of processing loose materials and the amount of equipment involved is a drying unit based on a multifunctional energy converter (MFEC). In the works that were published earlier, attention was paid to the design features of MFEC, issues of design, mathematical modeling and simulation of transient modes under load [8][9][10][11].…”

Design Features of the Screw Unit for Processing Bulk Substances

This article is devoted to the description of the multifunctional energy converter (MFEC) design of the screw type. MFEC is an induction motor with an external hollow solid rotor. On the surface of the rotor, which is a steel pipe, the turns of the screw conveyer are welded. When supplying power to the stator winding (which visually resembles the wound rotor of an induction motor), the magnetic field not only causes the rotor to rotate, but also, due to the formation of eddy currents, heats the latter. Thus, the idea of combining several functional components is realized in one device: mixing, heating and transportation along the turns of the screw of bulk material. The specified operations are implemented without the use of an external electric drive, heaters, but only due to the principle of operation of the MFEC. Previously, the two-module design of the MFEC was investigated, but experimental studies indicated certain shortcomings of the chosen approach. In this work, an attempt is made to show an alternative configuration of the MFEC, based on the execution of independent single modules that can be combined into a continuous screw thanks to transitional fasteners. In addition, the approach to the power supply and module management system has been revised. This article is one of a series of works devoted to a detailed description of the design of the MFEC.
