Sažetak
Traditionally, the power factor of electric power systems has been improved using capacitors. Capacitors can interact with harmonics injected into the power system by non-linear loads, causing damage to the capacitors or other power system components. Due to the shortage of reactive power in the power system of eastern Croatia, capacitors were installed on a 110 kV busbar at the Djakovo 220/110 kV transformer station. Voltage distortion was measured on the 110 kV busbar before the installation of capacitors. Due to a possible resonance with the network, a filter facility was designed. Prior to the installation of the filter facility, the network was modelled, and harmonic results were calculated. The filter facility is modelled using the "EasyPower Spectrum" program for harmonic propagation analysis. Before and after the installation of filters, network and filter frequency characteristics, and all standard distortion indices were determined. Voltage and current indices, VTHD, ITHD, IRSS, VRSS, were determined.
