The invention discloses a method for realizing MMS information simulation and point alignment of an intelligent substation. The method comprises the following steps: checking information imported intoa file; sending an analog signal corresponding to the file information to a background according to the formulated rule in response to that the check is passed; and receiving a reverse-checking filefed back by the background, and performing reverse-checking verification on the sent analog signal through the reverse-checking file. According to the invention, the method for realizing MMS information simulation and point alignment of the intelligent substation is realized; the functions and behaviors of opposite-end equipment (or system) in communication connection with the IED are debugged andverified by adopting analog signals, so that the complexity of device and system debugging is greatly simplified, and the integrated debugging efficiency of the intelligent substation automation system is improved.
