The invention relates to an AC-DC coordination control effect evaluation method and an AC-DC coordination control effect evaluation device based on multi-source data. The method comprises the following steps: monitoring and acquiring action information of a safety and stability control device in real time; acquiring AC-DC line measurement data; when monitoring action information, extracting AC-DC line measurement data from a moment t-2 to a moment t and AC-DC line measurement data from the moment t to a moment t+3 from a relation database according to the receiving moment t of the action information; acquiring and analyzing an action strategy table file corresponding to the action information, and acquiring action start conditions, regulation start value and regulation data; judging whether the action of the safety and stability control device meets the action start conditions according to the AC-DC line measurement data; and acquiring an evaluation result through comparison. By adopting the method provided by the invention, grid model information, WAMS measurement information, safety control action information and safety control device strategy table file information can be integrated and then comprehensively analyzed, so that a scientific evaluation conclusion about the AC-DC coordination control effect is formed.
