The invention discloses a distributed phase modifier configuration method and device for improving a new energy multi-station short circuit ratio. The method comprises the following steps: constructing a power grid simulation digital model of a power system comprising a plurality of new energy stations; calculating the short-circuit ratio of each new energy station in the selected research range of the power grid simulation digital model; determining a first distributed phase modifier configuration scheme set of the number and capacity of distributed phase modifiers which can be accessed to each new energy station; according to the short-circuit ratio of each new energy field station and the first distributed phase modifier configuration scheme set, determining a second distributed phase modifier configuration scheme set meeting a preset minimum short-circuit ratio requirement; selecting a third distributed phase modifier configuration scheme set from the second distributed phase modifier configuration scheme
