The invention relates to an intelligent substation automatic dynamic simulation test method based on an SSD file. The method comprises the steps of firstly, automatically establishing a system model based on the SSD file; secondly, associating secondary equipment with a primary system according to the established system model; and finally, carrying out an automatic dynamic simulation standard test. According to the method, the dynamic simulation test difficulty of an intelligent substation can be reduced, an automatic test scheme is formed, and a test process can be standardized easily.
