The invention relates to a near-region line flow adjusting method in a DC layered access mode. According to the sensitivity information of layered access DC high and low end converters and a generator for a receiving-end converter station near-region to-be-adjusted line, control means of reducing a DC power and stopping one or multiple converters of a certain DC layer are comprehensively considered, flow adjustment on lines in heavy loads or exceeding stable limits in a receiving-end converter station near region is realized, a power grid operation mode can be conveniently arranged, and safe and stable power grid operation is guaranteed. The method is advantaged in that the method can be applied to online calculation and offline analysis, and technical supports can be provided for power grid programming and operation analysis personnel.
