South Network smart meter safety automatic detection technology has reached the international advanced level

[China Instrument Network Instrument R&D] A few days ago, China Southern Power Grid Company's key project “Research and Application of Key Technologies for Energy Metering and Security Cost Control System” passed the appraisal, and the overall results have reached the international advanced level; among them, the design of the security cost control key management mechanism and Implementation, smart meter automatic detection technology has reached the international advanced level.


Electric energy metering safety and reliability is one of the important indicators of electric energy metering quality management, and it is also an important indicator for the power supply companies to provide continuous and reliable power supply to customers. In recent years, China Southern Power Grid Corporation has been conducting in-depth studies on automation, security, expense control, and operation support systems for electric energy metering. It requires highly reliable and high-security chip products to “protect it”.

The project lasted five years of research and put forward a cryptographic solution based on the secret algorithm for the security cost control system in the field of energy metering, and built a multi-layered multi-layer covering the "main station-metering collection terminal-smart meter-user card" of China Southern Power Grid Corporation. The level key system and multiple security interaction authentication systems solve the problem of grid marketing measurement business data and measurement device safety protection.

The project has been granted 20 patents and 5 software copyrights; the project research results have been widely applied in the China Southern Power Grid, implementing 8 sets of key management systems, 1057 sets of detection software, 20 million pieces of smart metering security chips, and measurement 216 ciphers.
