ABSTRACT

Objective. Evaluation of the results of parametric optimization, which is reduced to the analysis of the optimal values of the upper maximum pressure level in the pneumatic system at different set values of compressed air flow consumed by pneumatic receivers in terms of their practical feasibility.

Research methodology. The developed digital mathematical model of the electromechanical system "electric network - compressor - pneumatic network" developed at the department of power supply systems, which is based on the efficiency of the energy cycle, is used for research.

Research results. The analysis showed that the proposed control option with a "floating" upper pressure level, for systems of different performance, provides a reduction in electricity consumption consumed by the considered electromechanical systems. The savings can reach 13.5% and depend on the values of compressed air consumption, air intake, compressor performance and parameters of the electromechanical system.

Scientific novelty. The problem of parametric optimization of the mode of operation of the electromechanical system is solved, with restrictions on the allowable number of motor inclusions in a given period of time and the value of air pressure in the pneumatic network.

Practical meaning. According to the evaluation of the results of parametric optimization of the modes of operation of electromechanical systems in terms of their practical implementation, a method of implementing control, two-position with a "floating" upper pressure level is justified.

Keywords: electric motor, regulation, compressor, electromechanical system.
