The results of studies of the working process of a piston gas engine Perkins 4012 TESI are presented. The engine operates as a part of a stationary cogeneration installation and generates electric and thermal energy at a crankshaft rotation speed of 1500 rpm. In the course of experimental studies, the pressure in the cylinder of a reciprocating engine without an encoder was recorded at various loads: from idling to 600 kW. The technique for determining the position of the marking of the top dead point on the experimental indicator diagram was developed and implemented when this diagram is compared with the calculated theoretical one. It is established that the combustion process consists of two phases. The main phase of active heat release has the duration of 40–50 degrees from the crankshaft rotation. The afterburning phase also has the duration of 50–80 degrees. Theoretical calculations and studies were carried out using the “Double-Wiebe function” program. The indicators of the nature of combustion and the amount of combustion fuel in each phase are determined. The program “Double-Wiebe function” allowed to adequately simulate the working process of a gas piston engine when it operates on homogeneous mixtures. Differences in the values of the calculated and experimental parameters were: specific indicator fuel consumption is not more than 1%; indicator efficiency is not more than 0.5%; maximum combustion pressure is not more than 1%. The calculation model can be used in the modernization and design of reciprocating gas engines intended for operation as part of autonomous power installations.

The article proposes a combined system of emergency cooling of a two-unit nuclear power plant with constantly operating additional steam-turbine units and a two-channel emergency power system with diesel generators. To justify the competitiveness of the proposed combined emergency cooling system compared to the passive residual heat removal systems, we proposed a method based on the defining a multicriteria target function taking into account the influence of the safety factor, as well as technical and economic indicators on the resulting combination effect. Based on the case of the Novovoronezh NPP-2 project, the resulting economic effect from replacement of heat exchangers in the passive heat removal systems for additional low-power steam turbines was determined for two NPP power units. It is shown that the overall capital investments and operating costs are reduced under a slight increase in the risk of core damage, which does not exceed the IAEA standards.

Currently, the use of acoustic emission method is widely used in various fields. The method consists in detecting, recording and analysis of elastic vibrations that arise as a result of plastic deformation of solid media. The Laboratory of Acoustic Research of IKIR FEB RAS. The laboratory actively uses this method to monitor the geoacoustic emission occurring in the sound range during rock deformation. Perturbations of geoacoustic emission signals are of great interest for research and can often act as operational predictors of earthquakes. Geoacoustic pulses are characterized by a complex internal structure, a wide variety of time-domain waveforms, large amount of noise and short duration. Such features together with a huge amount of incoming data exclude manual processing and require an effective way to detect impulse anomalies in automatic mode. This paper proposes an algorithm for automatic detection of geoacoustic pulses. The algorithm is based on the use of an adaptive threshold automatically adjusted to the noise level in the signal. Mechanisms for detecting various pulse anomalies are considered. A method for defining the boundaries of selected events is also described. The received algorithm was tested on real signals with different degrees of noisiness.

An overview of new solutions in the field of traction electric drive is given: integrated starter-generator system, electrically controlled transmission system. Such systems relate to mechatronics for a number of reasons: the integration of several devices in one (starter and generator, mechanical and electromechanical converter), the management of several power flows simultaneously, increased reliability requirements, mass dimensions, control range, including in the second quadrant, the magnitude of the overload torque, increased requirements for the control system. The key element of the starter-generator system is the electromechanical converter, therefore advantages and disadvantages of new traction electric machines for AC drives are given. A key element of the electrically controlled transmission system is the power splitter, which can be mechanical, magnetic planetary gears and electric machines in two rotary versions. The composition and functions of the system, its advantages, disadvantages and prospects are given. It is shown that an electric drive with a field regulated reluctance machine possesses the qualities necessary for constructing the systems under consideration.

The experience of operating the model systems of ventilation and air-conditioning (VAC) showed their high energy and resource consumption, unreasonably increased dimensions, the lack of stability in maintaining the set control parameters and the inability of the system to optimize the operating modes of VAC to improve the economic efficiency of the equipment. The imperfection of the control modes of operation of VAC leads to the situation, there are significant overspending of energy resources, which leads to an unreasonable increase in the cost of operation of buildings and structures. The modern direction of automation development is characterized by a stable tendency to create special control computing complexes based on the use of micro-computers, programmable logic controllers, which requires improvement of algorithms of control systems VAC. There is a contradictory situation, characterized on the one hand, by the need to reduce the annual operating costs of VAC and the imperfection of VAC operating modes on the other. Разрешение данного противоречия составляет актуальность данной статьи. The article is devoted to the development of automatic control system VAC based on the organization of energy-saving modes of air treatment. A brief analysis of energy-saving modes of air treatment is given.

The main difficulty in applying the frequency synthesis method for multidimensional lumped systems is the necessity to transform control systems to the form that allows to consider the system as a complex of independent one-dimensional lumped systems, so that the interaction between the contours could be ignored. In this work considered spatially invariant distributed object described by differential equations in partial derivatives and carried out a comparison of distributed object continuous and discrete models dynamic characteristics. The paper shows that if the discrete analogs of spatial modes are the eigenvectors of the multidimensional object transfer matrix, the object is conventionally spatially invariant and can be described by the partial differential equation. The application of this method to multidimensional systems can allow synthesizing regulators in cases where the original transfer matrix of the object is not diagonally dominant, and let to describe the laws of object dynamics more accurate.

The relevance of the issues of using low-grade and wet organic fuels is determined by modern energy saving trends. In particular, this applies to the direction of involving low-grade fuels in the fuel energy balance and providing heat and electricity for the areas of decentralized energy supply. The paper deals with the process of high-temperature thermal decomposition of plant biomass waste by a combined pyrolysis-gasification method in a steam-air environment enriched with oxygen using solid oxide fuel cells (SOFC) to generate electricity. High enthalpy and high chemical activity of the gasifying agent allows the process of thermal decomposition to be carried out in an autothermal regime. The high-temperature regime and application of steam-air blast enriched with oxygen provides a high degree of conversion of waste from plant biomass to the combustible components of CO, CH4, H2, the resulting gas mixture. After the generation of electrical energy, the exhaust gases undergo complex purification from combustion products and cogeneration of residual thermal energy. In particular, purification from toxic nitrogen oxides (NOx) occurs, formation of dioxins, furans and other dangerous chlorinated derivatives of compounds is prevented. The potential acid components of the exhaust gases are neutralized. These components affect the kinetics of the process, oxidation-reduction reactions in SOFC and reduce its efficiency, as well as contamination of electrolyte membranes and degradation of electrode materials. The use of gasifying agents can significantly reduce the formation of toxic components in a mixture of combustible gases. The heat energy withdrawn at various sites of the plant is almost completely used for the needs of the cogeneration plant and its units, which allows achieving a total efficiency of at least 86%. The ability of the cogeneration unit to use variable gasifying agents allows to work on various types of solid waste and as a result to have a wide range of applications and operational capabilities.

The procedure of fuzzy optimization is considered as the problem of forklift path planning in a changing environment for a number of typical situations differing in the goals of the forklift and the constraints imposed both on control resources and on the behavior of forklifts. Simultaneously with the construction of trajectories of forklift, the synthesis of algorithms for the work of digital controllers of forklift control systems as hybrid continuous-discrete systems is carried out. The procedure for constructing control systems with fuzzy goals and constraints is based on the representation of control algorithms in the form of a priori non-fixed and time-variable systems of rules.

The procedure for constructing control systems with fuzzy goals and constraints is based on the representation of control algorithms in the form of a priori non-fixed and time-variable systems of rules.","PeriodicalId":177690,"journal":{"name":"2018 International Multi-Conference on Industrial Engineering and Modern Technologies (FarEastCon)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131813846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
