Harmonics are electric voltages and currents that appear on the electric power system as a result of non-linear electric loads. Non-linear loads include common office equipment such as computers and printers, Fluorescent lighting, battery chargers and also variable speed drives. Harmonic components should be reduced as much as possible. According to harmonic stability problem that was caused by the non-linear of converter, the simulation model was established based on the actual equipment situation of convert station. Harmonic instability may occur in high-voltage dc (HVDC) links due to dynamic interactions between HVDC terminals and the impedance of the dc lines or cables. In recent years, the issue of harmonics compensation has got considerable attention. The main purpose of this paper is to reduce the harmonics in transmission of power in HVDC system. THD values can be calculated using FFT analysis. Simulation model is developed in MATLAB/Simulink environment
