Opis:: The practice of operating AC electrical arc fumace power supply systems has shown that energizing unloaded fumace transformer can cause long lasting transients in filter circuits of static VAR compensators used in the supply systems. Examination of the supply system configuration impact on switching transient behaviour has been carried out by example of a 50 MVA arc fumace unit. The transient analysis has been carried out through simulating by Matlab/Simulink software.

Opis:: Passive filters are widely used to mitigate the effect of load harmonics on the supply power grid. Topology selection of the filters is based on the frequency bandwidth to be suppressed. Filter topologies comprising single-tuned filters and damped filters are the most popular in industrial power system applications. The article focuses on the influence of the damped C-type 2nd harmonic filter on the transients behavior under arc transformer energization in the arc furnace power supply system compensated by SVC. The examination results of transient currents and voltages across capacitors and reactors of the 3rd and 5th passive filters are compared for two topologies of the SVC filter circuits: with and without C-type filter. The Matlab/Simulink Software was used to modeling filter behavior during unload transformer switching-on.

Opis:: The practice of operating reactive power compensation systems involving passive multiple filter circuits (FC) configured by single–tuned filters has shown, that it’s energizing can cause damage of the filter components. Impact of feasible FC configurations, including FC with a C–type filter, on switching overvoltages and overcurrents under the harmonic filters energizing were analyzed. Influence of the filters tuning on transient behavior has been shown. The transient analysis has been carried out by simulating of the FC within Matlab/Simulink software.
