Abstract:
The harmonics generated by the AC side of the HVDC transmission system are analyzed, and a parallel active filtering scheme is proposed for the characteristics of the harmonics generated on the AC side of the HVDC transmission system, the active filter adopts the instantaneous reactive power theory for harmonic detection, maintains the stability of the capacitor voltage through PI control, and uses the high-frequency carrier PWM pulse width modulation technology to make the actual output current signal track command current signal. Finally, the dynamic simulation of the active filtering scheme is carried out, and the simulation results show that the active filtering scheme is very effective in filtering out the harmonics generated by the DC side of the HVDC transmission system, and the ideal results can be obtained.
