The invention provides a consistency verification method for a standard data exchange interface of a power grid system. The consistency verification method comprises the following steps: verifying a public data exchange interface: verifying a resource ID service function, verifying a resource inquiry service function and verifying an event service function; and verifying an operation interface of time sequence data management and access: verifying a specification consistency support degree function through a detection system, verifying a data reading function, judging whether the public data exchange interface is consistent or not, judging whether the operation interface of time sequence data management and access is consistent or not, and if the two interfaces are consistent, indicating that the standard data exchange interface of a power grid is consistent; and otherwise, indicating that the standard data exchange interface of the power grid is inconsistent, and tuning once again. According to the method provided by the invention, verification is performed according to a method for verifying most basic functions firstly, so that the data exchange interface can be verified efficiently and comprehensively in a system development process; the system development efficiency is increased; resources are saved; and the development cost is reduced.
