Abstract
With the mature of high power IGBT, VSC-HVDC technique is gradually adopted in principle power grid with higher voltage and capacity. At present, it is generally considered that compared with traditional HVDC technique, VSC-HVDC will save lots of land resources. However, it is not always the case. In this paper, two recent projects are used to compare the area between LCC-HVDC and VSC-HVDC. The factors which affect the area of LCC-HVDC converter station and VSC-HVDC converter station are analyzed. Generally, with the improvement of DC voltage, the advantage of VSC-HVDC for land saving would gradually decrease. The comparison between the area of LCC-HVDC and VSC-HDVC is mainly depend on DC rate Voltage, the nominal AC voltage, the account of groups for AC filter, etc.
