COMPARATIVE STUDY OF METHODS FOR ESTIMATING WEIBULL PARAMETERS TO IMPROVE ACCURACY OF PROBABILISTIC WIND ENERGY MODELS

Abstract. The article proposes an algorithm and results of comparison several methods for estimation Weibull distribution parameters used to fit long-term wind speed data distribution. The least squares method, maximum likelihood method, method of moments and its modification using the first and third moments were included in analysis. In performance analysis by Monte-Carlo simulation random samples and observed wind speed data from six weather stations located in Arctic territories of Russia were used. Goodness-of-fit was quantified using statistical criteria (coefficient of determination R2, Kolmogorov-Smirnov test) as well as comparisons of empirical and theoretical distribution moments and mean absolute percentage error of power density and annual wind energy. As a result best fitted probabilistic models for most wind speed data samples were obtained with modified method of moments. Mean absolute percentage error in annual wind energy calculated for average wind turbine operational speed range (4-25 m/s) does not exceed 5 % for all cases.

Key words: renewable energy, wind energy, Weibull distribution, Weibull parameters estimation, probabilistic models, Monte-Carlo simulation.

THERMAL EQUIVALENT OF SOLID MUNICIPAL WASTE

Abstract. The concept of “thermal equivalent of municipal solid waste” as the maximum possible amount of heat that can be obtained by thermal utilization of waste, the method of its calculation is presented. Various methods for calculating the calorific value of solid municipal waste are presented and their critical comparison is carried out. The range of values of the lower calorific value of solid municipal waste obtained experimentally is also given. According to these data, the net calorific value of waste ranges from 5024 to 9211 kJ/kg, the average calorific value is 6700 kJ/kg. The dynamics of changes in the morphological composition of municipal solid waste for the period 1975-2011 on the example of St. Petersburg is presented, it follows from the data that the organic part of municipal solid waste is currently 70-75 %. The article shows that due to the utilization of municipal solid waste with the generation of thermal energy, 2 to 8.6 % of the population’s heat demand can be covered. The possibility of using municipal solid waste as a local type of fuel in district heating systems, including bivalent ones, is substantiated. A schematic diagram of a bivalent heat supply system is presented and the principle of its operation is explained.

Key words: municipal solid waste, heat supplying, bivalent heat supplying systems, heat value, heat equivalent.

FUNCTIONING OF THE SMART GRID SYSTEM AT MODERNIZATION OF ELECTRIC NETWORKS WITH THE INTRODUCTION OF INTELLIGENT ACCOUNTING DEVICES

Abstract. The development of methods for organizing intelligent electric networks based on the SMART Grid concept provides the possibility of self-regulation and self-healing in real time of electric networks by changing their parameters and topology according to the current operating conditions, optimizing the planning of the power supply network, regulating the load, expanding market opportunities and creating a consumption culture based on them and stimulating economic development. Such an organization of intelligent electrical networks will significantly increase the level of security due to improved quality and reliability of power supply, as well as reduce system-wide energy costs. An assessment of the level of “intellectualization” of technological processes for supplying electricity is possible on the basis of the globally recognized Smart Grid concept, which reflects the capabilities of intelligent electric power industry, such as providing a universally two-way flow of electric energy and control information between power supply distances, substations and power devices in real time based on distributed computing and communications, as well as the organization of calculating the instant balance of demand, supply of electricity at any point in the network. At the same time, the importance of implementing electrical wiring in the context of ensuring operation in critical conditions remains important. The comparative possibility of increasing the capacity of the electric network when introducing intelligent electric networks and replacing the conductor elements with elements with an increased cross section is considered.

Key words: intelligent network, meter, energy loss, demandbalance, implementation efficiency.

FORECASTING DURABILITY AND RELIABILITY OF SEPARATOR FLAT RESET MATERIALS IN ANSYS WORKBENCH

Abstract. The purpose of this article is to study a model for predicting the multiaxial fatigue life of fiberglass and steel flat sieve separator. Existing methods for calculating the fatigue strength of fiberglass and steel are considered: nominal stress, comparative analysis, deformation and energy, based on the use of structural stresses, concepts of fracture mechanics. An analysis of the distribution of safety margins at each sieve point using the Ansys program is proposed. The safety margin of fiberglass in the impact zone of the separator sieve exceeds the safety margin of steel. Finding the values of the safety factor by the criterion of maximum voltage von Mises allows us to judge the reliability of the product as a whole. The proposed fatigue resource model based on S-N curves is used to predict the number of cycles to failure occurring under fixed load conditions. Based on the results of the fatigue analysis performed at Ansys, a plot of the service life is constructed. The diagram shows the most dangerous places in terms of fatigue failure. Based on the diagram of the service life, the service life of the material is determined - steel (106 cycles) - is slightly higher than that of fiberglass (1,7x104...106 cycles). From the point of view of reliability, steel and fiberglass will behave well when working with a drummer, since both are close in specific strength.

Key words: fatigue damage parameter, finite element analysis, durability prediction, multiaxial fatigue, periodic boundary condition, fiberglass.

IMPROVEMENT OF PROCESSES OF DISINFECTING AND DUSTYING OF THE AIR OF THE AGRICULTURAL SPACE ON THE BASIS OF ELECTRIC FILTERING OF AIR

Abstract. One of the problems in animal husbandry is the high density of animals in a limited space. This problem leads to an increase in energy consumption for creating an optimal microclimate in livestock buildings, an increase in the risk of spread of infections, and also to an increase in the environmental load on the environment. It is known that electrostatic precipitators arewidely usedas air purification of agricultural premises from dust. It was noted that the efficiency of microflora cleaning of agricultural premises air with electrostatic filters does not exceed 70%. From this it follows that after the passage of air through the electrostatic precipitator, a sufficient amount of microflora remains in the air. To solve this problem, it is proposed to improve the electrostatic precipitator by supplementing the installation with an additional zone the bactericidal radiation zone. It is assumed that this installation will increase the efficiency of dust removal and disinfection of the air of agricultural premises. It was established that during the long-term operation of electrostatic precipitators, a layer of settled aerosol and dust particles forms on the precipitation electrodes. The efficiency of dust removal and disinfection of the air with electrostatic precipitators is reduced due to poor cleaning of electrostatic precipitators from settled aerosol and dust particles on the precipitation electrodes. It is proposed to install a ventilation system in the upper part of the deposition zone. Regular automatic cleaning of the electrostatic precipitator will increase the service life of the installation.

Key words: disinfection of agricultural premises, dust removal of agricultural premises, electrostatic precipitator, bactericidal lamp.

DEVICE OF ELECTRO-THERMAL TREATMENT OF SEEDS

Abstract. The question is that even in addition to harm to human health, agricultural use of GM crops leads to a reduction of up to 30% in biodiversity: bacteria, worms, insects and environmental degradation. The mass extinction of bees in countries where transgenes are cultivated occurs because one has to constantly increase the amount of herbicides for growing GM crops. In 2000, an open letter to the governments of all countries asking to introduce a moratorium on the distribution of GMOs was signed by 828 scientists from 84 countries of the world, and over the past years the number of signatures on it has only increased. According to Greenpeace Russia, in 2005 in Moscow already about 50% of all food products contained GM ingredients. Now this figure has grown. Many scientists believe that the gigantic reserves of modern breeding methods have not yet been used. The authors have developed an environmentally friendly method of stimulating seeds, improving their productivity and productivity. The article discusses the experiment of treating seeds with water of contrasting temperatures together with alternating electric current of a certain value and subsequent laser irradiation. The optimal treatment regime for seeds of cucumber varieties “Aquarius”, melon “Kolkhoznitsa”, watermelon “Ogonyok” and other vegetable crops was experimentally determined. An integrated seed treatment device was developed and assembled, and an electrical diagram of the device was also presented.

Key words: water-thermal treatment, alternating electric current, seed stimulation, laser irradiation, electric circuit, device, working capacity, open contact, closed contact, electric valve.

AUTOMATED TEST DIAGNOSTICS OF ELECTRONIC CONTROL SYSTEMS FOR GAS-TURBINE ENGINES BASED ON ACTIVE IDENTIFICATION

Abstract. The article presents the concept of monitoring and diagnostics of electronic control systems for gas turbine engines (ESG GTD), which are part of an autonomous gas turbine power plant of low power, intended for power supply to agricultural consumers. The control and diagnostics of the self-propelled guns of a gas turbine engine is carried out by the transfer function coefficients of the controller and the control object, determined on the basis of active identification using special-purpose test signals in the form of time-power functions with strictly normalized characteristics that are given the status of reference signals. The control and diagnostics are based on three identically equal transfer functions: initial or diagnosed, identifiable or controlled, standard normalized, serving as a metrological basis. Based on their identity, the relationships between the monitored and diagnosed parameters are established, which are used to build algorithms and develop an information model for an automated control and diagnostic system for a gas turbine engine control system. Using the information model of an automated system for monitoring and diagnosing failures of an ESA GTE, one can obtain a set of information about the state and functioning of a control object. Through the information model, the sequence of functions performed by the human operator is determined, information sources are identified, a list of information signs characterizing the control and or control object is compiled. The outlined concept of monitoring and diagnosing failures of the gas-turbine engine ESA can be implemented in automated monitoring and diagnostics systems (ASKD) designed to debug the ESA at the production stage, where the controller interacts with the gas turbine engine model, and in the bench test stage, the controller interacts with the natural gas turbine engine.

Key words: gasturbineengine, electronic controlsystem, transferfunction, activeidentification, test signals, information model for monitoring and diagnostics.

THE RATIONAL USE OF VEHICLES IN THE PRODUCTION PROCESS

Abstract. The problem of the current state of the machine and tractor fleet and the engineering and technical service in Russia is raised. The state of the agricultural industry is examined, focusing on the transport support of technological processes when harvesting grain crops. Modern methods of transporting grain from fields to the current of farms of various groups of combines are considered, where an analysis was carried out, the results of which determined the inexpedient number of combines and cars in the harvesting and transport complex. The practical value of the issues discussed in the proposed work questions is confirmed by the fact that in modern market conditions the proposed mathematical optimization methods are of significant importance, allowing, along with other methods, to establish the dependence of optimization parameters on various factors, to predict the processes under consideration, to find optimal solutions for using vehicles in the production process. Using statistical observations, the article proposes to use a block diagram of an algorithm for solving the problem of determining the numerical characteristics of the functioning of the workflow, due to it a solution was found consisting in determining the maximum demand for cars over the entire array of fields, where the optimal use of transport was achieved using the compiled simulation model means for harvesting crops.

Key words: agriculture, grainharvesting, productionprocess, modeling algorithm of the harvesting and transport complex, vehicles, level of organization of harvesting and transport operations.

Abstract. This article describes the process of decomposition of methanol when it is fed into the power system of a diesel engine. The formation of a methanol-air mixture (MVS) is described in detail, chemical reactions occurring in different temperature regimes are composed. The results of theoretical calculations on the change in the volume content of nitrogen oxides in the combustion products of the MVC and their impact on the economic and mechanical performance of the diesel 2H 10.5/12.0 are presented. The review of scientific works of scientists of ready developments of existing systems of injection of watermethanol in the engine is carried out. A patent review of watermethanol supply to diesel engines is also presented. The scheme of watermethanol supply to the air supply system of the D-240 engine was developed. On the basis of the upgraded model, the optimal concentration of pure methanol in the watermethanol mixture was determined, which is 30%. According to calculations and practical studies, the selection of existing nozzles was made, their optimal diameter was selected within 0.6-0.2 mm, the operating pressure for spraying the liquid to the dispersed state was determined in the value of 7 MPa. Adjustment of watermethanol supply to each nozzle was performed, which determined the average optimal fluid flow rate of 30 ml / minute, ensuring stable operation of the engine. The article also presents the test reports carried out on the factory sample and the upgraded sample of the installation of watermethanol injection into the engine. Based on the data obtained, the next stage of development of our development will begin with laboratory tests of the working model.

Key words: methanol-air mixture, D-240 engine modernization, alternative fuel, multicomponent fuel, exhaust gas toxicity reduction, pyrolysis, watermethanol injection into the engine, water and watermethanol injectors, engine efficienc.
