Abstract

This paper presents an engineering study on the modernization of a K-1500 compressor electric drive system operated within the technological equipment of a large metallurgical enterprise. The exact facility location and identifying production data are not disclosed because of industrial security considerations. The existing drive concept is based on a high-power synchronous motor started directly from a 6 kV network through an excitation system. Operational analysis showed that this configuration is associated with high starting currents, vibration loads, thermal stress, limited restart capability and a negative influence on the plant power supply system. As a modernization solution, the study proposes a controlled drive system based on a 6 kV medium-voltage variable frequency drive, a squirrel-cage induction motor HRN3 719-48E and an Atlas Copco compressor unit replacing the former K-1500 installation. The methodology combines literature review, engineering comparison, analysis of technical parameters and MATLAB/Simulink modeling of transient processes. The results show that the proposed drive structure provides smoother acceleration, lower electromechanical stress, reduced network impact and improved controllability of the compressor unit.
