Description

Technical field: [0001] The invention relates to electric energy metering technology, in particular to an electronic smart electric energy meter. Background technique: [0002] In order to implement sustainable development and solve the contradiction between environment and development, many countries in the world are actively exploring green energy to reduce environmental pollution and non-renewable resource loss by traditional power generation methods, or to save investment, reduce energy consumption, and improve system security And flexibility, using a power supply method that combines a large grid system and a distributed power generation system. After systematic scientific design and reasonable planning of the electric energy market, the distributed small-scale power supply system can not only solve the energy problem of residents, but also feed the surplus electric energy back to the grid to realize the compensation of electricity, thereby reducing the burden on the power s...
