Beijing Metrology Institute won the second prize of Science and Technology Progress of China Metrology and Testing Society

The award-winning project "Study on Quality Assessment and Risk Early Warning Technology of Smart Grid Energy Metering System" is aimed at China's current "one-time life-test" energy metering system (that is, the first calibration of the smart meter before installation in the laboratory, no calibration will be performed after the installation is completed, to the verification The method of all rotation after the cycle (eight years) has the risk of misalignment in use, and may cause a lot of waste.

Under the guidance of the Municipal Market Supervision Bureau, the Beijing Institute of Metrology and Inspection, in conjunction with the Beijing Electric Power Research Institute, lasted seven years. Through the long-term measurement performance tracking analysis of tens of millions of meters, two original quality assessment theories were formed: The theory of batch electric energy meter measurement risk assessment based on component failure analysis and the theory of using neural network to quantify the influence of environmental conditions on energy metering performance; the establishment of an energy reference standard value array under non-standard conditions, the first systematic solution in the world The technical problems of key nodes such as pre-installation quality assessment, post-installation life prediction and high-accuracy field calibration in the life cycle evaluation of smart metering performance. The overall technology of the project has reached the international leading level, and all three core technologies are internationally pioneered.

The “China Science and Technology Progress Award” is a provincial-level scientific and technological progress award registered in the National Science and Technology Awards Office. It is the highest award in the national measurement technology industry. The judges are composed of more than a dozen academicians. The award-winning units are mainly sponsored by the National Institute of Metrology, the Institute of Aerospace Science and Technology, and other famous research institutes such as Tsinghua University.

In recent years, Beijing Metrology Institute has closely focused on Beijing's key areas of social and economic development and major industrial needs, facing regional economic and social development, making scientific research into enterprises, writing papers in the industrial chain, and continuously improving its technological support capabilities. The results are constantly emerging. The research project of Beijing Institute of Metrology and Measurement Science has been widely recognized and highly appraised by experts and scholars including academicians. It has won the second prize of Science and Technology Progress of China Metrology and Testing Society for two consecutive years.
