This chapter proposes the interpretation of the concept of “power supply system efficiency” and a mathematical model that focuses on minimization of electricity supply expenses while observing the time criteria. The research examines the constituents of the specified time criteria, the calculations of power outage time, and the time of power supply restoration. In addition, this chapter describes the constituents of implementation time for a technological connection of rural consumers to electric networks and the statistical data on the time of inconsistency between power quality and regulatory requirements. Furthermore, this chapter investigates the applying possibility of the proposed mathematical model for the development of measures that can improve power supply system efficiency. In order to improve electricity supply reliability of rural consumers, the technical condition monitoring of power lines and electrical network automation is carried out.

The chapter analyzes the power supply restoration time. The analysis shows that this time consists of the time for obtaining information about failure, the time of information recognition about failure, the damage repair time and the time of connection and disconnection harmonization. Each of them, in turn, is also considered in more detail that allows identifying reserves to reduce the power supply outage time. The chapter proposes reducing the power supply restoration time by going to the monitoring system combination of both operating modes and technical condition of power networks. Based on the study results, there are methods allowing to reduce the power supply outage time of rural consumers by means of automating rural electrical networks and improving the operating mode monitoring of power supply systems. The chapter also suggests a set of devices that allows to implement the proposed methods.

Electrical energy in the thermal processes of agricultural production has a number of technical and technological advantages in comparison with other energy carriers. At the same time, electricity is the most high-quality but expensive type of energy. The effective use of electrical energy in thermal processes is possible with the implementation of all its advantages over fuel energy. This requires a system of technical, economic, and energy analysis and the selection justification of the most effective systems and technical means of heat supply of stationary agricultural technological processes. The chapter presents functional and technological schemes, physical models, the experimentally obtained dependencies, parameters, and operating regimes of the developed energy-saving electrical equipment and systems for the main thermal technological processes.

Crop production is largely associated with a number of external factors that affect productivity, quality, and cost of production. A significant part of the cost (20-40%) occurs on post-harvest processing, storage, and preparation for feeding. These processes include drying, decontamination, steaming, micronisation, etc. The chapter describes the electrotechnology impacts and their use in processes of grain processing. The chapter deals with the classification of electrophysical methods of influence, correlated with the processes in which they can be applied. It describes the required levels of exposure and the resulting values of productivity, intensity, and other parameters, qualitatively describing the specific processes. The factors which can positively affect grain production include the use of ozone, ions, infrared, and microwave fields.
