In recent years, with the rapid development of smart grids, both domestic and foreign countries attach great importance to information security protection in the construction of smart grids, and various countries have invested a lot of manpower and material resources in this regard. However, due to the special requirements of smart grids on the environment and RFID With the characteristics of the technology itself, the research and application of high-security RFID technology for smart grids are all in their infancy.
Smart grid high security RFID has a global unique identification that cannot be tampered with or copied. At the same time, data is encrypted and stored to ensure the confidentiality and integrity of data, which can improve the security and reliability of smart grid data. Smart grid high security RFID integrates the national secret SM7 security algorithm. The RFID electronic tag authentication process adopts a three-time data transmission authentication method. Through two-way authentication, data transmission is more secure, stable and reliable.
Smart grid high security RFID technology has water resistance, high temperature resistance, long service life, large reading distance, data encryption, large storage data capacity (512bits user storage space), and convenient reading and writing of stored information that are not available in barcodes and QR codes. advantage. Smart grid high security RFID technology is used for smart grid equipment asset management, which can improve the automation level of equipment assets and ensure the security of equipment ledger information.
The integration of high-security RFID and current transformers of smart grids has been widely used in many provincial companies and transformer manufacturers. The management of the whole life cycle such as inspection and scrapping greatly saves the workload in storage and inspection, and reduces the production cost. It effectively solves the problem of malicious tampering of the current transformer nameplate and prevents the occurrence of the current transformer after installation. The phenomenon of electricity theft has achieved significant social and economic benefits.
Application goal
(1) Realize the management of the entire life cycle of smart grid equipment, reduce the workload of equipment storage, inspection and other links, and improve the automation level of equipment management.
(2) Ensure the uniqueness of the identification of smart grid equipment in the warehousing, distribution, inspection and other links.
(3) Improve the security and reliability of smart grid data.
Precautions
(1) The integration of the chip and power grid equipment does not affect the normal and safe operation of the equipment.
(2) When integrating injection molding with power grid equipment, pay attention to whether the injection molding material interferes with the UHF RFID radio frequency signal.
(3) There are many devices in the smart grid system. It is necessary to study the classification of smart grid high-security RFID technology, improve the automation level of smart grid equipment management, and improve the security and reliability of smart grid data.
