Smart Meter

In the past, all the instruments that people saw in the past were "fools". Now, with the development of technology, the instruments will be considered!

In recent years, the state has paid more attention to the energy conservation and environmental protection industry, and it has been identified as one of the seven strategic emerging industries planned during the “Twelfth Five-Year Plan” period in China. In addition, the tight energy supply, insufficient power supply, and low power quality have boosted the smart grid. Construction.

This has led to the development of the smart power meter market. From the past three years, the sales volume of the smart power meter industry in China was less than 2.5 million units in 2010, and it has grown to about 3.3 million units in 2011. This figure exceeded last year. 4 million units. The average annual compound growth rate reached 29.62% in the past three years. It is expected that by 2016, the growth of smart power meters in China will exceed 40%.

The network intelligent power meter is an intelligent device used for medium and low voltage systems. It integrates data acquisition and control functions. It has power parameter measurement and energy metering. It provides a communication interface and a computer monitoring system. It supports RS485 interface MODBUS communication. Agreement or multiple agreements. The large-size special liquid crystal module can display a plurality of information in real time and cooperate with a bright backlight to enable the operator to accurately read the data even when the light is poor. The operation mode is humane, the operator can grasp in a short time, reading data and parameter settings and other operations will become simple and easy. It is widely used in medium and low-voltage transmission and distribution automation systems, industrial automation systems, intelligent switchgears, building automation systems, negative control systems, energy management systems, and plant power assessment management.



According to the development plan of the State Grid Corporation of China, the development of the smart grid in China will go through three stages of development, namely, technology research and development and standard development, comprehensive construction and improvement. At present, the development of China's smart grid has entered a phase of comprehensive construction, which has created a huge market demand for smart meters.

After 2016, China's smart grid will enter the stage of perfect improvement, and some old and old meters will be upgraded. Therefore, after 2016, China's smart power meter market will continue to grow substantially.

The main applications of smart meters are:

â–  Energy Management Systems â–  Substation Automation Systems â–  Distribution Automation Systems â–  Hospital Power Monitoring Systems â–  Factory Automation Systems â–  Intelligent Buildings â–  Intelligent Switchboards

Power measurement - measuring dozens of commonly used power parameters: voltage, current, frequency, power factor, power...

Energy statistics - bidirectional four-quadrant active energy, reactive energy accumulation, multi-rate statistics, energy pulse output power quality analysis - up to 31 harmonic analysis, waveform factor / phone harmonics form factor / K coefficient analysis, three-phase Unbalance Analysis Load Monitoring - Active/Reactive/Assisted Demand Statistics, Line Voltage/Phase Current/Power Maximum and Minimum Statistics, All Statistics with Time Stamp Limit Alarm - Flexible and Powerful The constant value limit setting system can start multiple analog setting channels and logic setting channels at the same time.

Rich I/O configuration - up to 11 digital inputs, 5 relay outputs.

Analog interface - optional 1 4 ~ 20mA analog input, up to 2 4 ~ 20mA analog output.

Event record - 64 sequential event records (SOE).

Electric meters are not "fools" and become smart. I think there will be more smart meters that will make our lives more comfortable and easier.
