Abstract
Purpose. The purpose of this article is to develop a mathematical model of the power supply system of an administrative building with the use of a kinetic energy storage under the condition of a random load of the consumer during the day. Methodology. To conduct research, the theory of designing power supply systems for buildings, the theory of plotting electric load graphs, methods of the theory of electromechanical systems, methods of mathematical modeling were used. Results. The analysis of the kinetic energy storage in the power supply system of the building was carried out, the effect of the storage device design on the amount of accumulated capacity was determined. The construction of a kinetic storage with an AC motor and a flywheel with a variable moment of inertia is proposed. The effect of control parameters on power storage for the proposed drive design is investigated and general relationships are presented. A mathematical model of the energy exchange of the power supply system with a kinetic energy storage is developed. Originality. The developed mathematical model of energy exchange of the power supply system with a kinetic energy storage proves that by setting the law of kinetic energy storage we can effectively regulate the electric load schedule of the administrative building, and accordingly the load of the power supply system. Practical value. The application of the obtained mathematical model in practice will lead to an increase in reliability and quality of power supply for objects connected to the 0.4 kV electric grid.
