Smart Monitoring and Checking Technology of Substation Information based on Virtual Intelligent Electronic Device

Substation is the core node of power grid energy conversion and operation control. At present, digital and standardized smart substations have been extensively constructed. Data communication gateway machine information point table is the basis and key of information interaction between substation and master station. When building a new substation, it is necessary to manually compare the correctness of the information one by one between the station terminal and the dispatching master station. Thousands of information points make work efficiency very low, so A new method for automatic verification of substation monitoring information is proposed, which based on the total station configuration file and remote control information configuration file of smart substations. Besides, virtual IED(Intelligent Electronic Device, IED) are used instead of physical IED to build a system to realize the automatic verification system of new substation monitoring information. It provides a new effective means for checking the information point table of newly-built substations.
