About This Chapter

This document describes the concepts, principles, and applications of Advanced Metering

Infrastructure (AMI).

1.1 AMI

1.1.1 Introduction to AMI

Definition

Advanced Metering Infrastructure (AMI) is a network that measures, collects, and stores

electricity information. It is an application of the Internet of Things in the electricity industry.

Ethernet

As shown in Figure 1-1, AMI consists of smart meters, smart terminals, communication

network, front end processors, and meter data management (MDM):

lSmart meter

Is an electrical meter that records electricity consumption every hour or less and

communicates that information at least daily back to the utility for monitoring and billing.

lSmart terminal

Huawei AR500 Industrial Switch Routers

Feature Description - AMI 1 Feature Description - AMI

Issue 01 (2013-5-10) Huawei Proprietary and Confidential

Collects and stores data from kilowatt-hour meters, and transmits meter data and electrical

abnormalities to the front end processor. AR500s, RouterA in Figure 1-1, are smart

terminals.

lcommunication network

Is a network that connects smart terminals and front end processors through Ethernet,

connects smart terminals and electrical meters through RS485.

lFront end processor

Collects meter data, maintains communication channels, collects and delivers commands,

and reports the device status.

lMDM

Manages, maintains, and analyzes meter data, and provides web and basic service

applications.

Purpose

The traditional meter reading system uses manual meter reading, which consumes manpower

and may cause economic loss because of incorrect meter data collected.

AMI solves the problems in the traditional meter reading system by implementing automatic

meter reading, pre-payment, anti-theft, line loss analysis, and energy management. AMI reduces

power grid O&M costs, improves grid management efficiency, and saves energy.

Benefits

AMI establishes two-way communication between electricity systems and users. This promotes

interaction between the electricity systems and users, enlivens the market, and enables electricity

companies to provide better services for users.

1.1.2 AMI Functions

AMI consists of smart meters, smart terminals, communication network, front end processors,

and MDM. The AR500 is a smart terminal that allows communication between electricity

systems and users.

The AR500 can function as a data concentrator to collect data from smart meters and provide

data services for front end processors. In addition, the AR500 can be used as a router in the

electricity industry.

The AR500 provides the following functions:

lData collection

Collects real-time data, historical data, event data, and status data. The data collection

process complies with IEC62056 (DLMS/COSEM).

lData storage

Provides cyclic storage for minor and major events and historical data including the load

curve, hour frozen data, daily frozen data, and monthly frozen data.

lData communication

Provides real-time data, historical data, event data, clock synchronization, and data

forwarding. The data communication process complies with IEC62056 (DLMS/COSEM).

lNetworking

Huawei AR500 Industrial Switch Routers

Feature Description - AMI 1 Feature Description - AMI

Issue 01 (2013-5-10) Huawei Proprietary and Confidential

Provides various uplink, local, and downstream networking modes. The AR500 connects

to upstream front end processors through FE/SFP lines, connects to other AR500s through

FE, and connects to downstream smart meters through RS485 lines.

lOperation, maintenance, and management

Provides configuration management, terminal maintenance, broadcast timing, and user

management.

Data Collection

Meter Data Collection

The AR500 collects meter data using real-time meter reading, timed meter reading, and

supplementary meter reading. Meter data includes real-time data, historical data, and event data.

Historical data includes load curve data, hour frozen data, daily frozen data, and monthly frozen

data.
