Functions of smart home meters
Smart home electricity meters requirements: In October 2009, China put forward the standards of state grid smart meters enterprise, and had made a more clear requirement for smart meters. Although this year's standards are in the process of being fully revised, the basic requirements for smart meters are still clear, and it normally has the following functions. 1. Two-way power transmission and metering functions are required as the in-door interface of the power grid. On the one hand, the power grid delivers safe and high-quality power to users' electrical equipment through smart meters. On the other hand, with the wide application of new energy, many distributed new energy sources, such as wind energy and solar energy, have been fully used by users. This kind of micro-distributed energy can also be fed back into the power grid through smart meters and connected with the power grid. Therefore, it is necessary for smart meters to have two-way power transmission and metering...
