Concern of overvoltages on power filters in industrial electrical networks
Harmonic power filters are widely used in industrial electrical grids, which make it possible to improve the voltage quality on the power supply system buses and to increase the load power factors. Selecting the scheme and parameters of the filter-compensation unit is related to the requirements for compensation of the harmonic currents and load reactive power, the characteristics of the power supply configuration and its operating conditions, as well as the indices of transients that may occur during the operational switching.
