Özet

In this paper, firstly, a monopolar High Voltage Direct Current (HVDC) transmission system model has been formed. Series, parallel and series-parallel active direct current filter designs were carried out to suppress harmonics caused by the converters in this HVDC transmission system. Simulations of the designed HVDC transmission system using these filter were carried out in MATLAB Simulink. Waveforms and total harmonic distortion (THD) values of load current and voltage were obtained in this transmission system model for filtered and unfiltered conditions. Harmonics in the load voltage and current were suppressed to a large extent by active direct current filter used in the HVDC transmission system. Furthermore, THD values for current and voltage were obtained significantly below 5%. According to these results, designed active direct current filters which have simple structure and not complex controller offer significant advantages.
