What are the new functions of smart energy meters compared with traditional energy meters?

Smart energy meter consists of measurement unit, data processing unit, communication unit, etc. It has the functions of electric energy measurement, information storage and processing, real-time monitoring, automatic control and information interaction. Compared with traditional energy meters, smart meters have the following functions in addition to the basic metering functions: bi-directional metering of active and reactive energy, and support for the access of distributed energy users. It has the functions of ladder tariff, prepayment and remote power on/off, and supports intelligent demand side management. Real-time monitoring of grid operation status, power quality and environmental parameters, and support for intelligent power consumption and energy services. It is equipped with online monitoring, diagnosis, alarm and intelligent processing functions for abnormal electricity consumption, and meets the demand for fault processing and online monitoring of metering devices. Equipped with a special security encryption module to ensure the safe storage, operation and transmission of power meter information.
