THE ACCOUNT OF LOSSES IN THE CALCULATION OF VALVE-INDUCTOR GENERATOR

Abstract. Calculation of electric machines is traditionally carried out by methods based on the assumption of sinusoidal currents and voltages. Any deviation from their sinusoidal shape, even if the addition of one additional harmonic, the second or third, causes some difficulties in the application of these methods. As for switched electric machines, powered by a source of pulse voltages, and phase currents which are extremely non-sinusoidal shape, the use of traditional methods of calculation leads to large errors. Valve-inductor generators are switched machines, the phases of which are powered by an electronic switch from a DC voltage source. Development of methods of calculation of machines of this type is an urgent task. The proposed calculation method takes into account the main losses of the generator. Losses in steel are taken into account by calculating the critical frequency, losses in copper winding − the calculation of the current values in a number of sections of the switching cycle of the generator. The period of change of currents and voltages is divided into a number of sections, each of which derivatives of currents and voltages are continuous. For each section, the energy consumed and stored is calculated, the energy lost and, as a result, the energy produced by the generator is calculated. The main losses are taken into account: losses in steel at critical frequency and losses in copper windings, calculated using the current values at each site.

Key words: valve-inductor generator, toothed zone, frequency Converter, flux coupling, magnetic conductivity.

THE APPLICATION OF FUZZY LOGIC FOR REACTIVE POWER  COMPENSATION IN ELECTRIC NETWORKS

Abstract. Maintaining the quality of voltage in the power supply network, as well as reactive power compensation are key tasks to ensure the efficiency of electrical complexes, which include load nodes with nonlinear volt-ampere characteristic. Compensation of higher current harmonics by existing methods and algorithms with the use of filter-compensating units makes it possible to solve the problem in the framework of the process of non-linear load current variability. Non-linear load consumption is accompanied by a number of processes of unpredictable nature, which are manifested in the corresponding variability of the harmonic composition of the total load current. This circumstance can radically affect the magnitude and vector of the reactive power flow in the network and adversely affect the quality of reactive power control by existing means. At the moment, intelligent control based on fuzzy logic has a strong position in many areas of science and technology. In some cases, devices that use fuzzy control are preferable to devices that are controlled by traditional algorithms. In the article the algorithm and the scheme of regulation by condenser installations in networks with nonlinear loading which are constructed on mathematical tools of fuzzy logic are developed. The results of simulation modeling analysis of the proposed fuzzy algorithm on the example of 14-node IEEE scheme are presented and analyzed. The obtained results prove that with harmonic composition exceeding the established norms, the developed algorithm allows to eliminate the excess load of capacitors from the currents of higher harmonics.

Key words: reactive power, electric network, batteries of static capacitors, nonlinear load, fuzzy logic, fuzzy sets.

PREREQUISITES FOR THE APPLICATION OF ENERGY PERFORMANCE CONTRACTS IN RUSSIA 

Abstract. Energy service contract (ESC) – a contract involving the performance of a specialized energy service company (ESC) a full range of works on the implementation of energy-saving technologies at the customer's enterprise. Payment, as a rule, is made by the customer after the project at the expense of funds saved due to the introduction of energy-saving technologies. Usually, energy service contracts are concluded for a period of 6 months to 5-7 years (the maximum period is limited by the ability of Russian banks to lend to ESC for long terms). In this paper we consider the definition of the energy service contract, its basic concepts, types of contracts. The content of the energy service contract is analyzed. The order of work of the energy service company (ESC) is given. The main criteria for choosing an energy service company are considered in detail. The advantages of the energy service contract are given. The analysis of performance Contracting in European countries and in Russia. The concept of energy service is considered. The problems arising at application of energy service contracts at the enterprises of Russia are listed. Thus, in contrast to the traditional approach to energy saving (where the burden of energy-saving measures in the form of energy audit and implementation of the planned projects falls on the power companies as a non-core and secondary task with the use of own funds of enterprises and carrying risks for the implementation of projects), the approach based on energy service contracts allows. 

Key words: energy service contract, energy saving, energy service company (ESCO), energy efficiency, energy saving technologies.

THERMOSTABILITY AND UNEVEN HEATING AS FACTORS OF INFLUENCE ON THE MODE OF DRYING GRAIN

Abstract. A description of the characteristic grain thermal stability properties is given. The factors affecting the thermal stability of grain are listed. Observed that chemicals grain has the least resistance proteins of the embryo, and then, in ascending order, the endosperm, which should be considered when organizing and conducting the process of drying grain as seed and food purposes. It is shown that for mine direct-flow the grain dryers is characterized by the phenomenon of overheating of the individual layers of the grain, to estimate which of the proposed formula for the coefficient of overheating, which should be used to calculate the maximum average temperature to which to heat the grain based on its thermostability. The description of schemes of work of the mine grain dryer with one and two circuits of recirculation is given. The definition of the circulation coefficient, as well as the formula that should be used for its calculation, with the inclusion of the coefficient of proportionality, taking into account the design features of the dryer. Based on the results of modeling the process of drying wheat grain at different combinations of the coefficient of proportionality (and circulation) in the first and second circuits, humidity and temperature of the recirculated grain, the initial temperature and humidity of raw grain, it is shown that for recirculating dryers the phenomenon of overheating of the entire mass of the recirculated grain relative to the maximum permissible value determined by its thermal stability is possible. It is recommended to include the circulation coefficient in the concept of drying mode for different types of recirculation dryers, indicating the corresponding values of the coefficient of proportionality. The factors allowing to control the drying process in the mine direct-flow and recirculation grain dryers as from the position of exclusion of the phenomena of overheating, drying and obtaining dried grain with the specified final parameters are established.

Key words: thermostability, grain dryer, the recirculating ratio over temperature, the coefficient of proportionality, modeling, drying, control.

THE POSSIBILITY OF USING ENERGY ACCUMULATING HEATING INSTALLATIONS IN AGRICULTURAL PREMISES

Abstract. Energy saving management of energy-saving installations, the effect of energy saving when using optimal control, energy-consuming objects and features of energy-saving management, formalization of energy-saving management tasks, tariff stimulation of energy saving is considered, the algorithm of optimal choice of power plant is considered, the possibility of regulation of thermal load on weather conditions (wind, air humidity, ambient temperature) with the use of neural networks is considered. Energy-saving management with the use of energy-accumulating installations shows that at present their control systems practically do not use the possibilities of energy-saving management. There are a large number of statements of problems of energy-saving management of dynamic objects, as well as structural schemes of control systems. An important factor in achieving the effect of energy saving is to determine the optimal control actions, taking into account possible changes in the States of operation. Modern requirements of practice to the accuracy of predictive calculations lead to the fact that previously developed methods do not always provide the required accuracy of the results. Therefore, new approaches to electric load forecasting are currently being proposed, developed and implemented. These new methods include neural networks and fuzzy neural networks. The method based on fuzzy neural network is the best in terms of prediction accuracy. The average prediction error of this method is 2.5...1.5 %. The maximum error of prediction among the compared techniques is regression analysis, a 3.5...3,0 %. For a neural network, the average prediction error is 2.9...2.1 %.

Key words: energy-saving management, energy storage installation, heat storage, optimal management, energy saving effect, two-rate electricity, neural networks, adaptive forecasting systems.

DEVELOPMENT OF MEASURES TO IMPROVE THE ENERGY EFFICIENCY OF HOT WATER SYSTEMS

Abstract. The article presents ways to improve the energy efficiency of centralized hot water supply systems (WSS) of buildings. It is noted that the implementation of measures to reduce heat losses in existing hot water systems by using improved thermal insulation materials for pipelines, shell and tube heat exchangers instead of plate heat exchangers, temperature and pressure control can reduce heat consumption in the system. However, more significant energy savings can be achieved by changing the circulation flow rate of the coolant in the system and in this paper improving the efficiency of domestic hot water systems are encouraged to implement impact on the circulation flow rate of the coolant in the hot water supply system with automated regulation. By means of the mathematical description the analytical expression allowing to define sizes of the circulation flow rate of the heat carrier in system of WSS depending on speed of rotation of the circulation pump is received. On the basis of mathematical model calculation of necessary sizes of circulation of the heat carrier is made and selection of the equipment taking into account ensuring automatic control of the expense of the heat carrier in system of GVS is made. As a result of the introduction of automatic control of coolant flow, the amount of water in the circulating circuit of the WSS system during the period of observation decreased from the initial value of 24309.81 m3 to 7871.78 m3. In General, the introduction of automatic control of the coolant flow rate allowed to reduce the consumption of heat energy for heating circulating water by 44%, the power of heat losses in the circulation pipeline decreased by 59 %.

Key words: heat supply, hot water supply, centralized hot water supply system, regulation of coolant flow.

ESTIMATION OF OPERATIONAL PROPERTIES OF MOTOR OILS BY MEANS OF ELECTRICAL PARAMETERS

Abstract. Motor oil, like any substance, has certain electrical and optical characteristics, which, as well as physical and chemical parameters (PCP) quality, vary depending on the period of use of the oil. In order to study the possibility of using electrophysical parameters to assess the quality and changes in the performance properties of motor oil, specialists of Penza universities conducted laboratory and operational experiments. Experimental dependences of the electrophysical and optical parameters of the engine oil on the mileage of the car, as well as their dependence on the main performance indicators of the engine oil, regulated by GOST. The obtained dependences show that the electrical and optical parameters can be used to control the limit state of the running engine oil. Culling the oil when the work can be carried out according to the acceptance indicators. Analysis of the research results showed that with the help of electrical and physical parameters it is possible to reliably determine the values of physical and chemical parameters of motor oils working in the car, and therefore to determine the deadline for their operation.

Key words: engine oil, engine, oil resource, oil change periodicity, vehicle mileage, dielectric constant, optical radiation absorption coefficient, kinematic viscosity, density, flash point.

NONPARAMETRIC ESTIMATION 80% OF THE RESOURCE BY REPEATEDLY CENSORED SAMPLE 

Abstract. The article deals with the case of termination of tests (observations) for various reasons, the result of which is a right-censored sample. The proposed three criteria of distinctness censored samples. The first two criteria are based on the distribution functions of individual developments to failure and to censorship, and on a uniform distribution, and characterize the sampling structure, that is, the location on the numerical axis of failures and censors. The third criterion, the coefficient of censorship, is equal to the share of non-failed products. Taking into account that by the present time a lot of estimations of distribution functions on censored samples are known, the authors solved the problem of finding the areas of their application for the estimation of 80% resource using simulation. Areas of application were established depending on the values of the criteria of distinctiveness. The technique was tested on the results of the performance tests, capital re-fied tractors DT-75, YAMZ-240Б. The relative error of estimation of 80% resource according to the proposed method does not exceed 7% and indicates the possibility of estimating the durability index for a shorter period of time, not reaching all the products to the limit state. For the considered objects the duration of operational tests could be reduced by more than a year.

Key words: censored sampling, estimation of distribution functions, the criteria of distinctness, 80-percent share.

THE CHOICE OF MEASUREMENT EQUIPMENT FOR THE QUALITY INSPECTION OF THE PISTONS IN THE REPAIR OF PRODUCTION

Abstract. To date, the most important criterion in the selection of quality control is considered to be the economic consent of the consumer and the manufacturer of products. The specified quality at repair of cars is realized by a method of the organization of operations of control. Maintenance and repair of machines - quite time-consuming activities related to mechanical engineering, which should be provided methods of uniformity of measurements and determine the required accuracy. In compliance with the standards of accuracy control significantly reduces the loss of external and internal defects, which always occurs in the presence of not excluded measurement errors. Activities related to the update of metrological support, lead to an increase in the efficiency of input and output control in the enterprise of technical service. If an accurate measuring instrument is used, there will be an increase in savings by reducing mismatched and incorrectly rejected parts, but the cost of a high-precision measuring instrument and the cost of its use may adversely affect the dynamics of the emerging savings. A method of calculating the economic efficiency of the introduction of a new measuring instrument, which reflects the parameters in the form of losses from the measurement error, the current cost of measurement and one-time costs in the form of the cost of the measuring instrument. An example of the choice of measuring instruments for the control of the piston diameter of the ZMZ engine in the organization of input control and selective Assembly of the cylinder-piston group in the enterprise. Previously, for this operation, a lever micrometer Mr-100 was used, it was proposed to replace it with a lever bracket CP-100. As a result of calculation of economy it is revealed that the quantity of incorrectly accepted and incorrectly rejected details is 2 times reduced. Savings will be 13322 p. with the control program 1000 PCs.

Key words: measurement uncertainty, internal and external marriage, the cost of control, loss of control.

SYSTEM NOISE INSULATION STAND VIBROIMPACT HARDENING

Abstract. For vibratory finishing-strengthening processing of parts used stands vibro-impact strengthening. The advantage of this method is to ensure the uniformity of hardening on the surface and the possibility of hardening the entire surface at the same time. The disadvantages of the method, preventing its widespread use, include limited dynamic and technological capabilities, as well as the need for vibration and noise protection of workers. Therefore, in the present work, the required value of sound insulation of the vibration hardening installation and the conditions for the selection of sound-protective structures and materials used are determined. The installation for vibro-shock hardening of the spar pipes consists of a support and vibrating frames, its Length is much greater than the width and height. This condition allows you to develop a system of noise protection fencing planes or semi-cylindrical structures. To achieve sound insulation ability to sanitary standards selection of the use of "sandwich" panels, ie the number of layers and wall thickness elements. On the basis of these data, the layout of the shelter of a noise-protective structure consisting of three arched sections entering one another is selected. The experimental measurements show that the noise exposure levels are lower than the standard values. Therefore, it can be concluded that as a result of the installation of noise protection shelter noise levels in the working area of operators in the area of vibration shock hardening spars reduced to the maximum permissible values in the entire normalized frequency range.

Key words: vibro-hardening, pipe spars, noise-reducing design, the arched frame.

The calculations of the maximum length of the main line of fire hoses at different values of the ambient temperature, at which due to thermal characteristics does not occur icing. The analysis of the functional purpose of the main fire trucks and the impact on its main function – timely delivery of a sufficient amount of fire extinguishing agents to the fire source. The modes of operation of the pump-bag systems from the fire tanker are determined: normal operation under normal environmental conditions and their operation in the cold climate and icing of the hoses. The possible potential of involving mobile equipment of fire and rescue garrison is considered. The choice of the most important factor of efficiency decrease is mathematically proved. A solution to the problem of glaciation of pump-bag systems at low temperatures is proposed. 

Key words: low temperatures, efficiency of pump-bag systems, fire safety, fire truck.

WAYS TO IMPROVE THE REGULATORY FRAMEWORK OF THE REPUBLIC OF KAZAKHSTAN IN THE FIELD OF CHEMICAL SECURITY AND ITS INTEGRATION WITH INTERNATIONAL STANDARDS

Abstract. Prospects of development of chemical safety in the Republic of Kazakhstan are stated. The purpose of the work is to identify the main directions of development of the regulatory framework in the field of chemical safety in the Republic of Kazakhstan. The authors show significant differences between the regulatory bases of the world community and the Republic of Kazakhstan in terms of the definition of "emergency chemical hazardous substance"; given the classification of chemicals according to their hazard; labeling of chemicals; approaches to the identification of chemically hazardous objects. The regulatory framework of the Republic of Kazakhstan in the field of chemical safety and turnover of hazardous chemicals requires serious processing and harmonization with the system of classification and labeling of UN chemicals. The legislation of the Republic of Kazakhstan in the field of chemical safety is coordinated in two independent areas – industrial safety and environmental safety. This is one of the constraints affecting the degree of harmonization with international law. The facts presented in the article determine the need for a significant amount of work aimed at the formation of a single effective system of chemical safety management, based on the integration of the regulatory framework for chemical safety of the Republic of Kazakhstan with the existing international standards in this area.

Key words: chemical safety, chemically hazardous site, hazardous chemical, harmonization, statutory act, classification, labeling.
