Advanced Metering Infrastructure – The fundamental layer for Smart GridsElectronic Meters are virtual monitors of the electrical system, apart from recording
energy consumption for billing.
Meter Reading methods• Manual visual reading• Manual reading through Handheld units• Remote Meter Reading• Automated Meter Reading
Smart Meters can detect pre-configured alert conditions and notify these to a remote master.
Smart Meters can control supply of power based on pre-configured logic or due to a command from a Remote Master.
Smart meters can provide meaningful energy consumption data to a consumer in their home on an In-Home-Display device.
Advanced Metering Infrastructure is a system by which utility can remotely acquire meter data automatically and on demand, be notified of events, and can control supply of power to individual consumption points.

LT consumer meters on PLC
Typical AMI Architecture
HES
LT consumer meters on Radio
Communication over GPRS
Communication over GPRS
Head-end System acquires meter reading data at predefined regular intervals.
On demand meter reading.
Critical Events occurring at meter end notified to Head-end system immediately on occurrence.
Meter can be configured remotely Remote meter connect /disconnect can be done from HES through DCU for Load Control with configurable pre-programmed reconnect attempts and lockout intervals.

AMI is characterised by
Large Volume of unattended, geographically spread
remote machines that have to
communicate continuously in near Realtime with
Head -End machine
Communication Infrastructure is the backbone of such systems
