Overview of AMI

Overview of AMI

This section describes the definition, purpose, and benefits of AMI.

Definition

The Advanced Metering Infrastructure (AMI) is a complete network system that performs automated meter data reading and controls smart meters. It is a mature electrical power industry Internet of Things (IoT) application and applies to communication networks of other smart meters, such as energy meters and gas meters.

Figure 1-1  AMI networking diagram

As shown in Figure 1-1, AMI consists of five components: smart meter (meter for short), data concentrator unit (DCU) gateway, communication network, data collection platform (DCP) front-end processor & Enterprise Energy Module (EEM), and Customer Information System (CIS).
  • Meter

    Record up to 1 hour of electricity consumption and exchange information with other devices to implement monitoring and accounting.

  • DCU gateway

    Collect and store data of meters and exchange meter data and electricity exception information with a front-end processor. Currently, AR500&AR530 series routers are used as DCU gateways.

  • Communication network

    DCU gateways and DCP front-end processors communicate using FE/SFP or 3G. DCU gateways and meters communicate over RS485, power line communications (PLC), ZigBee, or radio frequency (RF) channels.

  • DCP&EEM

    Collect meter data, deliver meter data reading instructions, and report the device status and alarm information. DCP front-end processor is referred as front-end processor. A front-end processor is the core component of DCP&EEM, and the EEM provides the graphical interactive interface.

    Front-end processors can also directly communicate with GPRS meters.

  • MS

    Uniformly manages information about DCUs and smart meters and periodically obtains data collected by collection tasks.

  • CIS

    Collect, collate, and analyze MS data to implement data management and meter data reading management. Additionally, CIS can analyze electricity exceptions and line losses for report management, O&M, and management.

Purpose

Traditional meter data reading systems use manual meter data reading. Manual meter data reading wastes manpower, is prone to errors, and has difficulties in data input and statistical analysis. In addition, traditional meter data reading systems suffer from severe line loss and cannot prevent power theft.

The AMI system overcomes these drawbacks. It is capable of automatic meter data reading, pre-payment, power-theft deterrence, load control, line loss analysis, and energy efficiency management, effectively reducing grid operation and maintenance costs, improving grid management and efficiency, and conserving energy.

Benefits

The AMI system establishes bidirectional communication between power systems and users, facilitates management, significantly reduces maintenance costs, and enhances services of power companies.
