This paper investigates a mathematical model of one elements of the power supply system - power transmission lines. The type of models depends on the initial simplifications, which in turn are determined by the complexity of the physics of processes. The task of improving the accuracy of modeling of emergency processes in the power system is due to the significant complexity of modern power systems and their equipment, high-speed relay protection, automation of emergency management and the introduction of higher-speed switching equipment. One of the reasons for a significant number of serious emergencies in the system is the lack of complete and reliable information for modeling modes in the design and operation of power systems. The development of a mathematical model of a three-phase power line, which provides adequate reflection of both normal and emergency processes, is relevant. The advanced mathematical model of power transmission lines allows to investigate various operational modes of electric networks. The improved mathematical model of the power transmission line reflects all the features of physical processes at state modes and transient process and provides sufficient accuracy of the results. The type of mathematical model of power transmission lines depends on the accepted simplifications, depending on the task of research. The purpose of this work is to analyze the mathematical model of the power transmission line to study the modes of operation of the power supply system, with the possibility of its application to take into account all the design features of overhead and cable power lines. The mathematical model of the power line for the study of the modes of operation of the power supply system is analyzed. It is used to take into account the design features of overhead and cable power lines, skin effect.

To implement the objective of steady operation of the marine observation buoy system on the sea throughout the year,based on energy balance between supply and demand, this paper presents the mathematical model of solar energy power supply system derived from double batteries switching technology. The batteries are divided into main batteries and auxiliary batteries. The main batteries are used regularly and the auxiliary batteries are used in periodic rainy weather. The main advantage of this model is that the capacity of auxiliary batteries can be dynamic calculated based on the numbers of maximum continuous rainy days and minimum intervals between rainy days. The batteries capacity is sufficient but not redundant. This design project has been tested on marine buoy and the accuracy of the model is splendid for most engineering projects.

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.
