What is AMI smart meter

AMI meter, also known as smart meter, is an indispensable terminal sensor in smart grid, which plays a vital role in the power industry. Here's a breakdown of the AMI smart meter:

Definition and function

AMI intelligent watt-hour meter is a kind of advanced electric energy measuring equipment with functions of electric energy measurement, data collection, remote communication and monitoring. It not only has the metering function of traditional electric meter, but also realizes the real-time connection and data interaction with smart grid by introducing modern communication technology.

Second, the main function

Remote Communication: AMI intelligent watt-hour meter adopts wireless communication technology to realize real-time connection with power distribution network, and can transmit power consumption data and receive instructions remotely. This enables the power company to know the user's electricity consumption in real time, remote meter reading and monitoring.

Data Acquisition and analysis: AMI intelligent watt-hour meter can accurately and efficiently collect user's electricity data, including current, voltage, power, electricity, etc. , provide users with detailed information on electricity consumption. These data are of great significance for load forecasting, grid optimization and energy management of power companies.

Real-time monitoring and control: AMI Smart Watt-hour meter can real-time monitor the user's power consumption, through the remote control function to adjust the user's power consumption behavior, to achieve the intelligent management of power consumption. For example, when the load power is too large to automatically cut off the power supply, or when the power supply is tight set time-to-time power supply to achieve the goal of orderly power consumption.

Diversity of applications: Ami Smart meters can be used in a variety of scenarios, including homes, commercial buildings and industrial plants and other places to meet the needs of different users of electricity. Its flexibility makes it an important part of the smart grid.
