The article considers the main provisions of the author’s model of reliability of electrical power networks and system fault development allowing to analitically identify the key technical and economic parameters of electrical power networks reliability taking into account the locations of the generating capacities and electrical loads, operation modes, their dynamic and static stability, as well as to calculate short circuit currents. The model also considers open-phase operation modes of networks for one-phase short circuits and allows selecting the most effective operation mode. The calculations are finalized with evaluation of final calculation estimates the average annual undersupply of electric power and economic losses of (damages to) consumers due to supply failures.

The article considers technologies for improvement of reliability and performance of combined urban heating systems. A method for estimation of reliability of combined heating systems is provided and comparative appraisal of reliability parameters for heating systems of various types is made.

The article considers issues of application of heat exchangers with capillary slot channels. An approach to designing the heat-exchange area taking into consideration its optimal geometry, optimal relation between the areas and thermal heads is proposed.

The article considers issues of the history, modern status and efficiency of foreign and domestic training equipment. Need for a normative evaluation of the efficiency and quality of training equipment is substantiated. The term “didactic efficiency” is defined.

The article is dedicated to organization of a system for development of an energy provider’s candidates pool through the example of JSC Kubanenergo. The relevance of this area of focus is due to severe shortage of properly qualified specialists at the labor market, lack of field-specific professional development programs at industry educational institutions for “key” specialties.

The article provides equations to calculate thermal losses to the environment from knockout drums. It considers various operation modes of knockout drums and results of calculation of heat emission coefficients and thermal losses through the example of removing drops from fumes at motor-fuel equipment. The influence of materials used for heat insulation on thermal losses is demonstrated.

The article considers topical issues related to emergence of defects at technical facilities and their reliable diagnostics. A microsystem able to operate in the real-time mode allowing for drawbacks of existing systems is proposed. The article describes advantages of using the microstructure and provides the microsystem operation algorithm . It also discusses issues of taking into consideration the noise level at industrial facilities and proposes the optimal sensor type.

New technologies for producing vegetable-origin bio-fuels employing achievements in nanotechnology and engineering are described.

The article provides a mathematical model for a three-dimensional turbulent flow and heat-and-mass transfer at the methane reformer embodied as a bundle of thermochemical elements with reaction mixture internal recirculation immersed in the flow of high-temperature combustion products. The conservation equations are formulated in the approximation of interpenetrating continuous where distributed resistances and interactions between them exist. The developed model is used for calculation of the spatial distribution of gas velocities, temperatures and concentrations in heating and heated (reformed) heat transfer agents, as well as the thermal state of the walls limiting their motion under the operating conditions of a standard reformer.

The article provides a method for performance evaluation of low-voltage devices while in service.

The article analyzes causes of damages to journal and thrust (journal-and-thrust) bearings at steam turbines. It provides results of a statistical study of damages for 25 years of operation for more than 800 steam turbines of 100 to 800 MW capacity of various types and brands.
