What are the differences between smart meters and functional me

  • As the home interface of the power grid, on the one hand, the power grid delivers safe and high-quality electrical energy to the user’s electrical equipment through smart electronic energy meter; and with the wide application of new energy, many distributed new energy sources, such as wind and solar, etc. It has been fully used on the user side. This kind of micro-distributed energy can also be fed back to the grid through smart meters to be connected to the grid. Therefore, smart meters need to have two-way power transmission and measurement functions.

    Of course, with the support of the powerful computing power of the MCU in the smart meter, the smart meter can also perform reliable power management, such as time-sharing management, user power classification management, maximum load control, and so on. Through these management, some high-energy-consuming equipment will be provided with preferential discounts from peak hours to non-peak hours, so as to realize peak-shift and avoid-peak power consumption, improve the operating efficiency of the power grid, and save users' expenses.

    This two-way communication includes two aspects, one is the two-way communication between the smart meter and the user interactive terminal, and the other is the two-way communication between the smart meter and the distribution network. As the connection unit between the user terminal and the power grid, the smart meter can manage the power consumption of the user terminal, and the user terminal can feed back the power consumption to the smart meter in real time; on the distribution network, the smart meter can pass The communication network sends electricity consumption information to the distribution network, and the distribution network can control smart digital kWh meter in real time through the communication network.
