Reactive power compensation in a powerful DC drives supply system

摘要

Power factor correction of the powerful industrial loads requires a design that is able to compensate for reactive power demand as well as for harmonic currents injected by the equipment into power supply system. In the circumstances many of industrial supply systems consist of a combination of tuned filters and a capacitor bank. The paper presents study results of interaction between capacitor banks and harmonic filters within an industrial power supply system.
