Transcript Getting ready for Advanced Metering Infrastructure

Getting Ready for Advance Metering
Infrastructure
AMI by definition
• Infrastructure of metering systems
• Automates most of the metering centred repetitive
activities
• Collects granular consumption data to deploy dynamic
pricing mechanisms
• New payment and customer service options
• Control of electrical load control within the home and or
businesses to improve system diversity
The communications hardware , software, associated system and
data management software that creates a network between
advanced meters and utility business systems which allows collection
and distribution of information to customers and the utility.
Is AMI same As AMR
AMR is primarily focused
on the ability to collect
data
AMI includes not only AMR,
but, a system that collects
time-differentiated energy
usage from advanced meters.
Primary purpose of AMR
Capable of providing
systems is customer
information which enables
billing, and reduced costs
utilities to provide demand
of meter reading.
response products &
customers participation.
AMR systems typically
comprise of static meters System supports other

devices, communication

Benefits of AMI - Utility
•
Elimination of manual metering capital costs
•
Fewer meter reading related issues and call center traffic.
•
Utilities can have innovative time-of-use price offers to suit
consumers’ needs; and
•
Interval data collection also helps to detect supply faults
and respond to them more quickly – Faster outage
detection and proactive restoration
•
•
Flexible billing cycle – Improved cash flow
Daily energy balancing for each DT
•
Transformer load management

load Control,
interface with In-Home devices.
• AMI / Smart Metering with various
communication technology.
• The products are 1Phase, 3Phase,CT/PT
operated meters.
AMI Components: In-Home Display
• A device which details the usage data in a graphical and
user friendly manner.
• The inhome display device can be connected to a meter
to create a Home Area Network via
– Zigbee communication device
– Hardwire connection between the meter and IHD
Secure Meters Limited
Network management System
• NMS is a combination of Hardware and Software used to
monitor and administer a network.
• This NMS needs to be linked to the ERP system
• What this system needs to do?
– Manage connect/ disconnect
– Manage alarm, events and other notifications
Meter Data Management (MDM)
• The definition of a meter data management solution can
vary based upon the implementation.
• At a minimum, MDM provides a database repository and
utility-specific business logic to:
– Automate and streamline the complex process of collecting meter
data from multiple meter data collection technologies
– Evaluate the quality of that data and generate estimates where
errors and gaps exist
– Deliver that data in the appropriate format to utility billing systems
• The critical role of an MDM system is to pre-process
granular interval meter data at large volumes very quickly.

AMI in India

What are the main drivers –

Demand shortage

Theft management

Load control

System automization

Better system economics

Govt. has taken a step forward in long term AMI direction,
by defining a sort of similar system in RAPDRP.

Combination of RF, DLC, GPRS communication network
seems to be favorable for most of the areas.

More work needs to be done wrt - detailing out system
functionalities, overall implementation and technology trials.

Planning AMI Deployment
Identify the current challenges of your business process.
Identify the future challenges that your business, your
customer and the society may encounter.
Define AMI vision statement based upon the above.
Start with a pay-back analysis. Telescopically plan your
AMI rollout keeping the most rewarding benefits in the
first few phases.
Don’t re-invent the wheel; take suitable help from
vendors and consultants as the cost of advice is
insignificant in terms of benefits and avoiding rework.
Planning AMI deployment
 Select communication technology and backend system on
the basis of above mentioned parameters.
Define specification accordingly.
 Bids to be called on the basis of clear understanding of
requirement of system NOT only product.
 Bids selection should be on the basis of complete system
implementation.
