An Approach to Improving Performance of the dc Filter in HVDC Transmission System

Article Preview

Abstract:

The Gui-Guang HVDC system in south china scheme with interconnections to the 500kV transmission to Guizhou and to Guangdong can exhibits, under certain operating conditions, the percussion of the dc filters impedance resonance problems. The analysis explains the dc filters impedance resonance. The influence of changing the dc filter parameters is also studied. Finally, an assessment is made for improve the dc filter performance
