Both have reached or approached the technical standards of developed countries, and production and research and development capabilities have also been able to meet the different needs of the international market, and the price advantage is obvious, and it has strong competitiveness in the international market. As China’s smart grid construction progresses and the corresponding residents’ incremental tariff reforms are proposed, the requirements for related energy metering tools such as power meters will also increase.
The smart energy meter is a new type of energy meter, which is composed of a measuring unit, a data processing unit and the like, and has functions of electric energy metering, information storage and processing, real-time monitoring, automatic control, and information exchange. Compared with the conventional ordinary energy meter, in addition to having basic metering functions, the smart meter is an all-electric meter with a hardware clock and a complete communication interface. It supports bidirectional metering, automatic acquisition, ladder pricing, time-of-use pricing, and freezing. , control, monitoring and other functions, with high reliability, high security level, and large storage capacity and other characteristics, can lay the foundation for the realization of distributed power measurement, two-way interactive services, smart home, smart community and so on.
Intelligent power meter is an important part of smart power, and it is the “terminal nerve†that realizes two-way interactive intelligent power consumption. The gap between China's smart grid technology and foreign advanced level is relatively small, and it is an important part of the low-carbon economy, so it has a stable high growth prospects. Compared with foreign countries, China's smart energy meters have complete functions and specifications, and they are relatively advanced in functions such as step price and load control, which can better meet the needs of China's smart grid construction work.
There are a large number of electricity consumers in China, as of the end of 2009, the State Grid Corporation of China

The number of power users in the system service reaches as many as 230 million. The promotion and application of smart energy meters requires huge investments, and the replacement of existing energy meters with smart energy meters requires a certain process. In addition, the functions and display contents of the smart energy meter are enriched and can provide users with many power services. However, replacing the smart energy meter requires understanding and support from the user, and the user also needs to have an understanding process.
The Chinese government plans to install 240 million smart meters throughout the country in the next five years. This means that in the three years between 2012 and 2015, the number of newly installed smart meters in China will reach 80 million. In the long run, taking into account China’s 1.3 billion people, the total number of smart meters installed in China should be 500 million, and China will become the world’s largest consumer market for smart meters.
