Justification of the power supply system for life support of rescue units and the injured population during field deployment

Introduction. Increasing of number, scale and duration of the consequences of emergency situations associated with the violation of the conditions of normal living of people requires the creation of temporary field accommodation points for the affected population and rescue units. At the same time, electric power supply in field temporary accommodation facilities plays a crucial role in the complex of tasks and measures aimed at providing life to the injured population and rescue units. At the same time, there are no mobile autonomous sources of electric energy for providing life support to people in the field in the organizational and staff structure of rescue units, and the existing sources of electric energy in the complexes of equipment used in areas of emergency situations cannot be used for these purposes. Therefore, it is necessary to develop a scientific and methodological approach to determine necessary and sufficient number of sources of electric energy for the power supply of the life support of the injured population and rescue units when they are placed in field temporary accommodation points. The purpose of the study. Electric power supply of field temporary accommodation points for the injured population and rescue units, ensuring the required reliability of electric power supply, maximizing its efficiency in the conditions of possible resource constraints and minimizing the influence of the uncertainty factor in the planning of electricity consumption. Research methods. The main provisions of the calculation of electrical loads, system theory, set theory, probability theory and the apparatus of mathematical statistics. The results of the study. A methodology has been developed that allows to justify the power of electric energy sources for the power supply of field temporary accommodation points for the injured population and rescue units, rational options for the power supply system, the nomenclature and number of electric energy sources for the life support of people in the field; to calculate the electric network; to evaluate the operation of the power supply system, based on the probability of failure-free operation of the source of electric energy; to justify the composition of engineering means to ensure the creation of the power supply system. Conclusion. The scientific and methodological approach for determining the composition of electric energy sources for the power supply of life support for the injured population and rescue units when they are placed in field temporary accommodation points is justified, which also allows to resolve the contradiction between the need to organize the power supply of life support for people in temporary accommodation points and the lack of a reasonable structure of electric energy sources for these purposes.
