| Abstract |
Background. The object of the study is the power supply system of machinebuilding enterprises. The subject of the study are shop consumers and sources of electricity. The aim of the work is to determine the optimal placement of shop substations to reduce energy
losses and metal consumption of power supply lines.
Materials and methods. The method of the distributed specific capacities is applied in the work. The optimization criteria are the amount of energy losses associated with its transmission, as well as the metal content of the power supply system.
Results. The method based on the fact that all loads distributed on the surface are represented by figures in the form of rotation bodies is proposed. The surface limiting these bodies is formed and determined by the product of the basic function on the amount of load power. The analysis of the results is carried out by replacing the group of electricity consumers with an equivalent consumer with the determination of the scattering radius.
Conclusions. The proposed method allows to design power supply systems with the best parameters and characteristics on the basis of minimum power losses during its transmission, as well as with minimum metal content. The method has versatility and can be used to determine the optimal location of the objects of the power supply system of settlements, and for the optimal placement of reactive power compensators. When installing compensators, in addition, there is an additional reduction in losses in the power grid, increases the quality of electricity supplied to the consumer.
