Weihai puts in the first smart substation that applies "data fingerprints" technology

On the evening of September 8th, the 220 kV Fuhe substation in Weihai, Shandong completed the entire station, and officially put it on operation. The Fuhe substation is a smart substation for the first "data fingerprint" technology of the national power grid system. It marks a major breakthrough in the power industry in ensuring the security of the equipment's operational data and preventing errors and tampering.

Data security is closely related to network security and is an important part of national sovereignty and national security. The power industry is related to the country and the people's livelihood, ensuring the security of the equipment for the operation of the equipment, and the resistance of the external malicious tampering is the key to maintaining power supply and benefiting people's livelihood. After the Fuhe substation of "data fingerprint" technology is used, it has the advantages of "security" and "efficient".

On the one hand, the "data fingerprint" adds a "password lock" to the running data of the power equipment. During the data modification process, it will automatically return to check in instructions to prevent the outside world from maliciously tampered with. Early warning to achieve active prevention error.

On the other hand, the application of "data fingerprint" technology has been realized for the first time in the national power grid system. The remote modification of the relay protection fixed value data has been realized, filling the gap of high -reliability remote modification of protection fixed value, and the application for electricity consumption of the response households will apply for electricity consumption. The protection time modification time is shortened from 3 hours to 5 minutes, providing users with more accurate and fast services. As a demonstration project of Weihai's "Exquisite Power Grid" construction, the application of a series of front -end intelligent technology in the Fuhe substation also provides a reference model for the construction of local city -level power grids, especially the construction of smart substations.
