[ China Instrument Network Instrument Development ] On November 14, the "Dual-core" smart meter based on the international legal standards for international legal measurement organization developed by State Grid Zhejiang Electric Power Co., Ltd. was first commissioned for network operation. This is the first smart meter in China that meets international recommendations and is tested by an internationally recognized electric energy meter testing laboratory.
The “double-core†smart meter is one of the important achievements of the State Grid Co., Ltd. “Technology Project “Dual-core†Intelligent Energy Meter Design and Detection Technology Based on IR46 Conceptâ€. On the basis of the existing smart meters in China, the meter combines the design concept of international high-end meters, which not only meets the technical requirements of international recommendations, but also meets the future development needs of China's smart grid.
The "double-core" smart meter can realize the free combination of measurement, software function and communication mode to adapt to the power consumption environment in China. Its function module supports software online upgrade, and the communication module supports online replacement. Each use area can be configured according to different management requirements, and the use mode is free and flexible, which can effectively save installation and maintenance costs.
The smart meter adopts a "double core" design scheme to make the metering part simpler and more reliable. Non-hardware function faults can be solved by a remote upgrade program, thereby reducing the field failure rate. In addition, compared with the existing smart meter, the “double-core†smart meter has increased the function expansion and upgrade function of the meter, and can be personalized for future smart home appliance control, “four-in-one†copying, customer energy recommendation, etc. Support is provided by the requirements.
State Grid Zhejiang Electric Power Co., Ltd. mainly undertakes the research and development and debugging of key technologies such as “double core†smart meter whole table optimization design technology, software and hardware configuration and implementation method, and non-metering part modular design. During the project development period, State Grid Zhejiang Electric Power set up a research group to innovate the dual core design with independent measurement core and management core. During the trial operation phase of the project, the company built its own virtual main station to assess the traditional functions such as metering performance and data acquisition and upload of “dual-core†smart meters. In the next step, the company will conduct a full-scale trial operation in Zhejiang Province, laying the foundation for the promotion and application of project results.
