· Intelligent physical devices that are either part of the grid (such as capacitors or automatic meter readers), or connected to the grid (such as remote cameras)
· A 2-way BPL communications network that connects the physical devices to the control centre where the data is stored.
· A set of applications and algorithms that process the collected data to provide high level, high value information and can control the physical devices.
The diagram below (AMR Architecture) shows how consumer meter readings are collected by the Data Collector and then transmitted back to the Operations Centre via BPL and fiber backhaul. Relays or remote ON/OFF devices connected to the network can also be actively controlled.
AMR Architecture
BPL (described in the previous section) is an enabler for the SMART GRID, providing the communications from the data collector to the control centre, allowing data collection as well as remote control of the intelligent devices.
