Abstract

This paper investigates the impact of synchronous machines on power quality in industrial environments. Synchronous machines, widely used in high-power applications, can improve various power quality issues such as reactive power imbalance, low power factor, and harmonic distortion. This study is focused on the power quality analysis in a heavy steel industry. As a solution to power quality issues analyses on the 4.2 MW/10 kV synchronous motor operation in a hot strip rolling mill is performed, under variable load conditions. The main necessary waveforms have been captured over several days, including voltage, current waveforms, power factor variations, and reactive power levels. To assess total harmonic distortion (THD), power factor performance, and overall power quality, the collected data has been analyzed. In order to maintain power quality within acceptable limits, the experimental obtained results show that the reactive power compensation and power factor correction acts as key points. The paper highlights the need for continuous monitoring and intelligent control strategies in facilities operating with synchronous machines. This case study serves as a practical example of how industrial systems can assess and mitigate the adverse effects of power quality disturbances.
