The invention provides a transformer protection realizing method based on multi-dimensional information. The method comprises the steps of (1) acquiring interval information, substation area information and zone information that cover electrical equipment, (2) extracting characteristic dimensional information from spatial dimensional information, and (3) constructing a main protection criterion, a backup protection criterion and a transformer protection and stability control coordination strategy of a transformer with the multi-dimensional information. The method comprehensively utilizes fault information of spatial dimension and characteristic dimension to achieve a relay protection criterion, so that the adaptability and movement performance of a protective device are improved.
