Misoperation-preventive locking realizing system and method in transformation process of substation

The invention discloses and provides a misoperation-preventive locking realizing system and method in the transformation process of a substation. A data interface conversion device is arranged between an original system and a novel system of the substation, so that the original system and the novel system are interacted; in the transformation process of the substation, the data interface conversion device can acquire data information of untransformed equipment for realizing the misoperation-preventive locking function of the novel system from the original system, so that the information for realizing the misoperation-preventive locking function in the novel system is complete, the normal running of the misoperation-preventive locking function of the equipment of the novel system is ensured, and further the safe and reliable running of the novel system of the substation is ensured.
