The article provides security measures required for the reconstruction of electrification systems at agricultural facilities. From the viewpoint of electric shock, agricultural facilities have a large number of premises indicated as “with increased danger” and “especially dangerous”. During operation, there is a great danger of electric shock to people and animals. In addition, there is a high degree of fire hazard. Concurrently, agricultural facilities are a source of a large number of harmful and hazardous production factors. Electrification systems are no exception. According to safety requirements, when performing any technological operations and processes, the negative impact of these factors on people, animals and the environment must be excluded or minimized. Hence, ensuring the safety of personnel is an urgent and crucial task in the reconstruction of electrification systems in agriculture.

Intensification of anaerobic processing of animal waste has a significant effect in comparison with other methods, which is expressed in a significant reduction in the pollution of environmental objects (air, water and soil) with chemicals and pathogenic microflora. The paper shows the developed technology of anaerobic processing of animal products, which allows one, on the one hand, to solve the environmental problems of animal husbandry, and on the other hand, to produce biogas fuel. The design features of the experimental setup for research are considered. The main indicators of the initial and re-loading manure and the properties of the resulting biogas have been analyzed. It was concluded that a promising direction for increasing the yield of biogas, as well as methane in its composition, it is advisable to improve the design of the bioreactor, to increase the productivity of the bioreactor and reduce the HRT through the use of a leaching layer and immobilization of microorganisms. At the same time, preliminary grinding of the raw material allows one to obtain a relatively better result.

The article is devoted to the analysis of the structure and methods of mathematical modeling of technological systems for the production of agricultural products. The article presents a study of technological subsystems of the use of machinery and equipment in the production and processing of agricultural products. Examples of elements of a technological system in an agro-industrial complex are a tractor, an agricultural machine, a combine harvester, a device or adapter, a working tool and equipment for maintenance. The structure of mathematical modeling of probabilistic processes of ensuring the reliability of technological systems, taking into account the modeling of the patterns of their functioning, has been developed. It is proposed to consider technological systems in the agro-industrial complex at four levels of the hierarchy: technological systems of operations of the crop, livestock and other agricultural and processing agricultural products of industries, technological systems of processes of crop production, animal husbandry, processing of raw materials of plant and animal origin, technological systems of production units and technological systems of production units of enterprises. A block diagram of the algorithm for modeling the implementation of the plan and an assessment of the achieved results of increasing reliability in the crop, livestock, processing industries of the agricultural enterprise is presented.
