communication, but currently require additional infrastructure to reduce
recursive communication between meters and meters to towers. These could
be converted to broadband IP
-
based networks as cost comes down.

Long Term Evolution (3GPP 4G technology)
at various frequencies
(licensed and unlicensed) and white space frequency spectrums will emerge
that will support more robust IP communications as wireless surpasses most
wired broadband networks, with dynamic encryption key generation for
security

What Exists Today And Future Functionality To
Deliver Smart Grid Data?
•
Currently repository of traditional asset data, product and maintenance
documentation
•
Captures maintenance procedures, typical values of metrics used for
assessing condition based monitoring

Asset Management Systems
Existing
Future
•
Will coordinate with condition based monitoring products which will assess
asset condition and performance and provide recommendation for loading
and maintenance activity. Currently available for strategic assets such as
Transformers, this will be expanded to cover other asset types over time.
Planning
Transmission and Distribution Planning Systems
•
Currently performs load flow and transmission capability analysis
•
Performs contingency analysis for dynamic and steady state stability
•
Performs off
-
line probabilistic based analysis of system reliability
Existing
Future
•
Will take condition assessment from CB Asset Analysis and calculate system
reliability impact of potential failure probabilities and recommend operating
practice based upon highest probability of occurrence
•
Perform transient analysis associated with consequence of asset failure
