The VSC-HVDC electric power quality analysis and research

New energy technology application will occupy more and more of the important position in the future of the electric power development. Traditional transmission mode has become the bottleneck which restricts the mass construction of the new energy electric power plant. The flexible DC transmission technology has more advantage than the traditional transmission technology in the application of new energy and distributed energy electric power system.This paper is based on study of electric power quality in VSC-HVDC and synthetically analyses on the electric power quality suppression.This paper expounds the conventional HVDC electric power quality characteristics. Analysis the application of VSC-HVDC to implications electric power quality after through comparing measure data between VSC-HVDC put operation and no put operation. On the basis of the analysis this paper put forward improving suggestions.
