The invention discloses a method for detecting consistency of intelligent electronic equipment loop information and SCD file loop information. The method starts with practical run loop information of the intelligent transformer station secondary equipment and the loop information in an engineering offline SCD file based on IEC61850 standards. According to the method, firstly, the engineering offline SCD file is analyzed, and the intelligent secondary equipment is taken as an object to form specific loop information of target equipment; then through access of an application network analyzer to a transformer station practical network, real-time monitoring, grasping, judgment and analysis of communication packets are realized to form real loop information of the target equipment; and finally, the two sets of the loop information are automatically compared to verify the consistency of the information, so as to ensure that an intelligent transformer station secondary loop runs in accordance with design requirements. The method is suitable for consistency detection of the intelligent device loop information and the SCD file loop model information based on the network analyzer in the capital construction, operation and maintenance stages of an intelligent transformer station.
