Configuration method and system for distributed phase modifier

The invention discloses a configuration method and system for a distributed phase modifier, and belongs to the technical field of power systems. The method provided by the invention comprises the following steps: embedding embedded data into BPA simulation data to generate target data; obtaining a stability characteristic simulation result, and based on the stability simulation result, determining a limit fault causing new energy offline; determining an influence range of the limited fault, and generating a preliminary configuration scheme of the distributed phase modifier based on the influence range; determining the configuration effect of the preliminary configuration scheme, adjusting the preliminary configuration scheme based on the configuration effect and the interactive influence of multiple direct currents of a sending end to generate a configuration scheme of the distributed phase modifier, and configuring the distributed phase modifier of the high-proportion new energy extra-high voltage direct cur
