In this article, power systems operating modes with both non-linear and linear loads and a capacitor bank are analyzed. In particular, the power supply systems of industrial enterprises are considered. The studies covered a daily change of linear load with the corresponding regulation of capacitor bank powers. Moreover, the capacitor powers at which the resonant modes arise at canonical harmonics were determined. The results show that the with regulation of the capacitors’ power on a daily basis, the voltage quality may not meet the requirements of power quality indicators. Furthermore, the capacitor units themselves may be overloaded with higher harmonic currents.
