The specific features of the control of the production process during the commissioning (the start-up and adjustment) of a thermal power plant are considered. The composition of the time spent on start-up and adjustment of modern high-tech equipment and engineering systems is considered. In the article a mathematical relationship between the duration of the start-up and adjustment works and the number of employees in the brigade, including the rate of efficiency in the use of an exceeding the optimum number of employees is described. A method for the development of rational management solutions was proposed and justified, providing for the ranking of start-up and adjustment works on their weight in the overall system of adjustment. For this purpose, the notion of technological priorities has been introduced, which take into account the degree of technological dependence of functional and technological nodes of the thermal power plant during the start-up and adjustment works. In addition, the concept of dynamic priorities that take into account the existing production situation at the time of making a decision to compile or adjust the calendar and operational and production plans in the commissioning period of the thermal power plant is being built.

The article considers the combination of a nuclear power plant (NPP) with water-cooled water reactors (WCWR) and a distillation desalination plant (DDP) with a horizontal-tube film evaporator (HTFE), their joint operation during periods of covering the dips of electric load schedules and thermo-economic efficiency. A number of advantages are presented in comparison with other methods of desalination, technical characteristics and cost of the DDP with a HTFE of made in Russia series, taking into account the costs not included (construction works, work on sea water supply, electric power, brine distillate, distillate). Such an energy complex makes it possible to increase the capacity factor of a nuclear reactor, as well as to solve the problem of lack of fresh water. The thermo-economic efficiency of this energy complex can be determined both by the complete and simplified algorithm by introducing the "thermo-economic index". Wherein the multi-product energy complex with steam supply from the turbine of the nuclear power plant to the DDP with HTFE should be compared with the version of work from special steam boiler plants (SBP). When analyzing the results of calculations using a simplified algorithm based on the thermo-economic index, the effect of the distillate cost factor on the market is noticeable, as well as the less efficient operation of the desalination plant fed with steam from the SBP as opposed to the steam extraction from the nuclear power plant, especially with increasing the number of hours of operation of the DDP of the HTFE.

A survey of the technical condition of porcelain high-voltage insulators (IEE 110/400 type) was carried out at two substations of JSC «Grid Company «Kazan electric networks», using the previously developed method of two-channel remote control. Based on the measurement of a set of partial discharge characteristics (PD) and their computer analysis, the technical condition of 38 PVIs was diagnosed with the division into four groups; Fully operational; Workable at the given time; Limited working capacity and requiring replacement during subsequent routine inspections; Completely inoperative, requiring immediate replacement.

The properties of electromagnetic fields in real conditions based on the fractal representations of the structure of material and design features of electrical equipment are studied. In calculating, the fractal characteristics methods are being suggested for the detection of redistribution of intensity of electromagnetic field due to the occurrence of diffraction, scattering and interaction with the heterogeneity of the components of equipment.

In this work, we calculated the optimal amount according to "annualized costs" criteria on the basis of model representations for the anodic grounding of the cathodic protection system in the form of a single hemisphere, which is located on the surface of the ground and contains coke backfilling. At the same time, calculations were made for a similar grounding, but without the use of coke filling, which allowed comparative analysis and calculation of their comparative economic efficiency, depending on the specific resistance of the soil. As a result of these calculations, we proposed a modernized anode ground with a normalized amount of coke filling, that has increased safety in comparison with the traditional product, since it allows to reduce  risks, caused by generation of positive DС stray currents of cathodic protection system, to other underground metal constructions. This quality of the proposed anode  grounding is especially important in urban areas and at the  territories of large industrial facilities characterized by an increased density of underground metal structures.

Essential technological and technical weaknesses were found among existing electrostatic dehydrators and electro-coalescing units. It was determined that the cause is critically low electrical resistivity and surface equipotentiality of metallic electrodes. Conceptually new technical solutions are suggested, that are based on the usage of electrically-conductive polymer composites as electrode material with imposed electro-physical and physico-chemical properties. The effectiveness of suggested solutions were confirmed by testing.

In article, presents the results of experimental determination of temperature distributions in characteristic sections of the working zone of a closed two-phase thermosyphon. A thermosyphon made of copper with a constant cross-sectional area is used to study heat transfer. The height of the heat exchanger is 161 mm, the thickness of the side walls is 1.5 mm, the bottom wall is 2 mm, the internal diameter of the evaporative part and the vapor channel is 39 mm. Experimental results give dependences of the change in the characteristic temperatures on the heat flux supplied to the bottom cover of the thermosyphon and the filling ratio. An increase in the heat flow at the bottom cover of the thermosyphon leads to a decrease in the temperature drop along the vapor channel and a reduction in the time to reach the stationary mode of operation. Experiments show that even at high thermal loads (up to 11,2  kW/m2) the temperature drops over the height of the thermosyphon do not exceed 9 K.

The content of components in gaseous fuels can vary widely, depending on the source, time and stage of development of a fuel field. The change in composition leads to a change in the thermotechnical characteristics of gas, which affects the efficiency of the combustion process.
