AMI (Advanced Metering Infrastructure)
|
| |
| WHAT IS AMI? |
| AMI, which is advanced
metering infrastructure. It is a system that measures, collects and
allows the analysis of energy usage from advanced devices. |
| HOW AMI WORKS |
| An AMI system allows the
SMLD to get meter reads from the meter on your home (or place of business)
back to a computer at the SMLD over a 900 MHz radio frequency.
The
read on your meter is taken electronically at a certain time each month
and is sent to a unit called a collector. The collector then sends
the information onto an SMLD computer for processing. |
| WHAT ARE THE BENEFITS OF AMI? |
- Increased
efficiency, speed, reliability and quality for the SMLD’s power
system.
- Efficient load profiling
- Immediate final and initial reads
- Efficient power failure detection
- Customer’s can view real-time
usage (future)
- More customer choices

The above shows a
simple diagram of a wireless two-way communication system with a fixed
network, utilizing a mesh network configuration. There are three
system components: the smart electric meter, the central
communication module (CCOM) and the host server.
The smart meter is located at the
customer’s premises; it transmits over a 900 MHZ, radio frequency to the
CCOM (which stores, sends and receives interval data to the host
server). The data in each CCOM is stored in non-volatile memory and
is encrypted for security until it is sent to the host server where
it is processed, stored and archived to magnetic media. From the
server, the information can then be automatically sent to the SMLD’s
billing server to process for billing and / or further analysis. |
