Abstract: |
HVDC different from AC transmission is that the inverter station of HVDC have plenty of characteristic harmonics which have damages to the AC network. In order to simplify the filtering device, 12- pulse converters are gradually adopted in the HVDC transmission. This paper build a 12-pulse HVDC model using PSCAD/EMTDC, and the filter’s model was built at rectifier side. The filtering effects of combination schemes are analyzed by simulation work, for the purpose of option screening. Finally, the optimization scheme can be chosen based on AHP, considering the THD and total investment.
