The method is used for metering and recording active, reactive, apparent electric energy, electric energy demand, voltage and current and other instantaneous quantities. The high-precision electronic multifunctional gateway electric energy meter is suitable for large and medium-sized industrial users and commercial users. From the late 60 s, electronic kilowatt-hour meters, also called static kilowatt-hour meters, were developed abroad. In comparison, for the same-grade meter, the electronic watt-hour meter has much better current linearity, voltage and frequency influence and smaller volume. The primary reason why the market demand for electronic watches is far less than that for mechanical watches is that they do not have the same product life at the same price. However, with the development of microelectronics, electronic watches have become technically mature. The industry analysis, along with the adjustment of the power utilization policy by the power department, the state gradually carries out the time-of-use electricity price policy, the traditional mechanical electric energy meter can not meet the requirement, and the replacement of the mechanical meter by an electronic meter is in great trend. The market demand of domestic civil electric meters is changing from taking mechanical electric energy meters as the main part to taking the electronic watch as the leading factor silently, and the concrete expression is from ordinary functional type ammeter to the electronic type electric energy meter direction transition of high-tech content and high added value such as long-life, time sharing, multi-functional.
With the vigorous development of electric power utilities and the comprehensive construction of smart grids, the role of smart gateway electric energy meters as key nodes for connecting the grid with users gradually emerges, and the smart gateway electric energy meters become one of basic devices of the smart grids and are also regarded as "precedent" for the development of the smart grids. The investment on the smart power grid in China stimulates the development of the smart power meters, and relevant data shows that China builds a smart power grid covering the whole country in 2020, and invests 4 trillion RMB to be used for relevant basic design construction, and the implementation of the grand plan relates to wide relevant fields of new energy power generation, new energy grid-connected access, large-capacity energy storage, extra-high voltage transmission, digital transformer substations, intelligent metering and the like, opens an unprecedented huge market for global power equipment enterprises, and simultaneously provides higher technical challenges for equipment manufacturers.
In summary, the problems of the prior art are as follows:
the existing watt-hour meter has incomplete functions, cannot realize the real-time monitoring of the quality of electric energy, and has poor quality, anti-interference capability and anti-attack capability.
The significance of solving the technical problems is as follows:
the national propulsion power mechanism reform, the plant network is separated, the price competition is carried out on the internet, and the demand of the gate table is greatly improved. With the implementation of development strategy in one way in China, a large number of electric energy meter products in China will be exported to regions such as southeast Asia, Arab and Africa, and the European market is gradually opened. The development of the high-performance gateway electric energy meter has remarkable economic benefit.
The demand of China for electric power is increased year by year, particularly, the load proportion occupied by the three-phase power in enterprises and industries is rapidly increased at present, and the total power consumption is increased year by year, so that the safe and stable operation of the electric energy meter has very important social significance. In addition, the production of the product has important social significance for promoting employment and driving the development of related industries.
Therefore, from the perspective of safety and economy, the research on the gateway electric energy meter has profound significance, and the economic benefit and the social benefit are very obvious.
