(Materials and methods) It has been shown that at present there are many agricultural consumers, interruptions in the power supply of which lead to significant damage, in this regard, closed power supply systems are becoming increasingly used, as the requirements for reliability, uninterrupted power supply and the quality of electricity supplied to the consumer are increasing.

Biogas can be obtained by biological and thermochemical methods. The first is the decomposi­tion of organic substances without air access due to the fermentation process, which takes place at a temperature of 30-40 degrees Celsius for «clean» waste (for example, microbiological industry) or 55-60 degrees Celsius for animal waste and urban wastewater. As a result of decomposition, biogas and a number of valuable components (nitrogen, phosphorus, potassium oxide) are formed, from which a highly effective organo-biofertilizer is prepared.

The total daily heat consumption and the capacity of the heat exchanger-agitator were determined using mathematical modeling and the laws of thermodynamics. (Results and discussion) The contents of the methane tank were heated by a heat exchanger using a coolant, and mixing was carried out using a mechanical stirrer combined into one heat exchanger–stirrer unit powered by an electric motor. It was shown that during the thermophilic process, more intensive and deeper fermentation of precipitation occurs, which contributes to a decrease in the volume of the methane tank, more effective destruction of helminths and weed seeds. It was found that during thermophilic fermentation, a greater amount of heat is needed to heat the sediment in the methane tank, 12-15 days are enough to disinfect the mass.

Taking into account the forecasts of many experts on the growth of distributed energy resources, the issue of studying methods for reducing electrical energy losses in distribution grids containing renewable energy sources is relevant.

The efficiency of processing these media can be improved by passing an electric current through them. (Research purpose) The research purpose is describing the mechanism of the thermal effect of electric current on organic dispersed hydraulic systems on the example of whey, searching for the role of the thermal factor in the regulating action of the current. (Materials and methods) Considered an organic colloidal solution simplistically as a two-phase dispersed system in which protein molecules act as a dispersed phase, and the rest of the colloidal system acts as a dispersed medium. In order to clarify the role of the thermal factor in the regulating action of the current, an electrical circuit for the replacement of a fragment of a medium with proteins was compiled. (Results and discussion) It was established that the electrical circuit of the substitution of the medium with protein molecules allowed calculating the processing parameters of colloidal solutions. Based on the results of the calculations carried out, it was shown that when such colloidal solutions are treated with electric current as a result of direct selective thermal action of the current, the temperature of protein molecules exceeds the average tempera­ture of the surrounding product by no more than 10 degrees Celsius. It was determined that the thermal effect of the current is an important factor in influencing colloidal solutions, however, an increase in temperature leads to an increase in energy consumption during electrical processing of these media. (Conclusions) The mechanism of the thermal effect of electric current on organic dispersed hydraulic systems – whey – was given. It was revealed that the obtained results are necessary for modeling electric and temperature fields that determine the uniformity and quality of material processing. It was stated that modeling the modes of electrical treatment of colloidal solutions will reduce the temperature of the medium and, consequently, the energy intensity of the process, optimize non-thermal factors during coagulation of colloidal solutions.","PeriodicalId":215527,"journal":{"name":"Elektrotekhnologii i elektrooborudovanie v APK","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132993284","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}

We solved the problem of improving the operation of milking machines and bringing machine milking closer to the physiological features of the milk-giving process.

(Materials and methods) Established that small gas turbine power and general-purpose power plants are not produced in Russia, research work was not systematic. It was determined that synchronous generators and gas turbine engines are used on two-shaft kinematic systems that reduce the rotation frequency of the generator rotor, where a large diameter of the free turbine entails a higher level of vibration, and due to the high level of sliding leads to a lower torque of the power plant at low rpm. (Results and discussion) It has been shown that the use of single-channel kinematic schemes contributes to simpler control, this opens up a wide prospect for their use in power plants for the purpose of supplying electricity to consumers and mobile agricultural vehicles. A new kinematic scheme of a high-speed generator has been developed, in which the rotor and stator interact with each other according to the type of sliding bearing. (Conclusions) The advantages of using a single-shaft kinematic scheme for the joint operation of a gas turbine engine with a high-speed synchronous generator have been revealed, which are expressed in a smaller moment of straining of the rotor and the absence of a sliding coefficient between the shafts. It was stated that as a result of using the proposed design of the power module, the reliability of the generator increases, the operating speed increases due to the use in the design of the polished outer surface of the rotor and the polished inner surface of the stator, working according to the type of sliding bearing, with forced oil supply at a pressure of 2-5 kilograms per square centimeter, at the same time, heat removal from the stator winding improves.","PeriodicalId":215527,"journal":{"name":"Elektrotekhnologii i elektrooborudovanie v APK","volume":"284 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125739088","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}
