Typical Municipality Challenges

Outstanding debts, increasing arrears and late payments

Bypassed or tampered meters (preventing revenue collection)

Difficulty (and sometimes security risk) to access customer properties to read or check the meters

High cost of administering and implementing disconnections and reconnections, often lack of cooperation and risk of poor customer relations as a result

Shortage of technical resources – estimated readings (negative customer relations due to this – and increased unwillingness to pay)

Shortage of power at peak times, leading to forced load shedding

AMI Technology


AMI ?

Advanced Metering Infrastructure (AMI) And end to end system consisting of head end

systems, data concentrator/s and meter devices that enables the utility to measure, collect, & analyse energy usage and communicate with devices

AMI extends (AMR) technology by providing two way communications, allowing commands to be sent to the meter for multiple purposes, including:

– Time-of-use pricing information for prepayment

– Demand-response actions such as load management

– Remote disconnect and reconnect actions

4


Smart Meter ?

General Industry Definition / Understanding Two-way communication between the meter and a central

head end or billing system

The meter has a Real Time Clock (typically synchronised by the Data Concentrator / Head end system)

The meter supports Time of Use and multiple tariffs

The head end system is able to remotely implement tasks such as disconnect and reconnect of the meter’s load switch

Meter is able to control load (power limiting) and the head end system is able to remotely change these parameter's

The head end system is able to read meter parameters

Solution Overview

STS prepayment meters have provided utilities throughout Africa

with an excellent revenue enhancement solution, but until

recently, have not supported extensive smart functionalities

Benefits

• Split prepayment solution for improved revenue protection

• Meter is typically installed in a pole top enclosure or street

kiosk while the Customer Interface Unit is in the household

• Solutions are available to enable improved revenue

protection and provide two way communications for auditing

and remote disconnections

• Have historically lacked smart capability such as TOU and

multiple tariff capabilities due to the available STS standardsCustomer

interface for taking care of the daily tasks related to handling

metering devices and scheduling meter readings

Features

• Perform various operations in an automated way

• Use tasks to schedule the system

• Automatic Meter Reading

• Execute control tasks (load switch control)

• Create groups and read consumption values from individual

units or unit groups

• Tasks can be executed directly or as scheduled tasks

• Typically interfaces to utility [billing] systems or Meter Data

Management Systems


Device Management – Individual Meter Controls

16

Units This view shows all the devices in the system,

this includes meters and Data Concentrators

Individual units (meters) may be selected

Direct reading tasks enable the user to select an individual meter or group of meter registers to be read on demand

Direct control tasks enable the user to select an individual meter or group of meters to be remotely controlled with various commands

Remote disconnect and reconnect is one example


On Demand Reading (e.g. Active Power A+)

Data Concentrator


DC450 Data Concentrator

19

Landis+Gyr’s DC450 G3-PLC

Data Concentrator

19

Overview

The DC450 is an active and intelligent concentrator that handles

communication between the system and the metering devices

Main Functions• Manages the inventory and the status of the PLC meters

• Continuous capture and storage of the metering data from metering devices according to the defined reading profiles

• Scheduled data push of metering data to Head-End System

• Maintaining the time and updating the metering device time

• Gathering statistics about PLC transmissions

• Supports DC and meter firmware updates

• Provides the AMI system with transparent access to individual meters (direct command on-demand)


DC Web Interface - SMS text message

20

SMS text message Field technician’s mobile number is able

to configured in the DC with a custom message (typically location of the DC or identification of the mini-sub)

DC450 sends the SMS text message to the technician in the event of a power failure

Enables utility to improve response to power failures at mini-substation level

Additionally serves as a revenue protection feature in the event that the power is fraudulently disconnected in the attempt to tamper the metering devices or Data Concentrators


DC Web Interface – G3 PAN Topology

21

G3-PLC PAN Topology This powerful graphical view shows

the G3 PAN topology

At the centre is the Data Concentrator and the view shows G3 smart meter devices in GREEN that have the best communications quality

The view also shows some meters in yellow or lighter shade of green that have a lower quality of communications (Possibly due to a noise source in the area or distance from the DC)

In the case an additional device has been located but it is not able to join the G3 PAN, this is shown in RED


Power Quality


Power Quality Information

23

Power Quality Features Smart meters are able to provide a wide range

of power quality information

Power quality information is able to be locally read via the optical interface or using the Customer Interface Unit

This valuable information is also able to be read remotely using a Head End System

Power Quality data is increasingly becoming valuable data to assist utilities in providing high quality service to their end consumers

Response to customer queries is further enhances when the utility staff are able to query the household power information on demand or analyse a trend of information over time (e.g. power failures, voltage sags and swells and much more)

Conclusion


Solutions for Typical Municipality Challenges ?

Outstanding debts, increasing arrears and late payments– Smart Prepayment solutions – up front payment, collection of historical arrears

Bypassed or tampered meters (preventing revenue collection)– Split metering, tamper sensing, remote fraud monitoring and events

Difficulty (and sometimes security risk) to access customer properties to read or check the meters– Smart meters enable remote auditing of meters – from the utility office

High cost of administering and implementing disconnections and reconnections, often lack of cooperation and risk of poor customer relations as a result– Remote disconnection and reconnection using smart meters (in smart post-payment mode)

Shortage of technical resources – estimated readings (negative customer relations due to this – and increased unwillingness to pay)– Automatic reading of smart meters via head end system and programmed profiles

Shortage of power at peak times, leading to forced load shedding– Load limiting made possible by smart and prepayment meters
