The core idea of Ubiquitous Electric Internet of Things (UEIOT) is to excavate the value of power grid data

to provide decision support for power grid business

and to help with the efficient operation of power grid. Substation secondary equipment extends to every node of system network to collect and produce huge amounts of data

which is an important data source of power grid. Therefore

the correct perception and efficient verification of data information will be the foundation of building UEIOT. At present

due to deviation of design concept

faults of manufacturing process and cost limitation

there is a blind area for monitoring the operation conditions of secondary equipment sampling system and parameter storage in substation. Once the failure occurs

a large number of erroneous data will be generated

which will lead to potential safety hazards and failure of upper management decision-making. Drawing lessons from the core connotation and framework of UEIOT and aiming at the correctness of protection data

measurement data and device parameters

an intelligent verification platform for substation data is established. Realtime detection of secondary equipment data sampling and device parameter storage system is realized

which guarantees the reliability and validity of data perception.
