Power factor correction and resonance in power systems

Abstract EN

The installation of power factor correction capacitors in power systems is one of the most effective ways to reduce energy consumption and costs of bills.

It also helps transformers to work to full capacity.

Although capacitors are easy to install and cheap to service, they can be the main disturbing element in the whole power system when installed in the presence of harmonics in the system, they cause resonance.

This paper presents a study of this problem, where capacitors are used to correct the power factor in the industrial power network of (Frydlant - line 53/22kV – Czech Republic).
