2 Human Metering Error

3 Real Time Monitoring is not Possible

Design Considerations for AMR Implementation

2.Tamper & Theft Activities

1 By-passing of Energy –(Kunda System)

2 Breaking of Meter Seal

3 Dimmer Effect, Neutral Breakage

4 Heavy Magnet Influence, Reverse connections

Design Considerations for AMR Implementation

3. Load Management & Control

1 Power supply shortage in the country

2 Unbalanced Power Consumption

3 Non-Efficient Management of load control

Design Considerations for AMR Implementation

4.Power Quality Analysis

Present system is unable to perform analysis of power quality e.g. power factor analysis, power supply stability etc.

Design Considerations for AMR Implementation

5.Energy Consumption Abnormality

Unable to report abnormal conditions instantly to prevent tamper activities.

Design Considerations for AMR Implementation

6.Non-Customized Services

1Multi-Tariff rate implementation , peak off-peak load

management is not easily possible.

RECOMMENDED INFRASTRUCTURE FOR UTILITY FOR AMR

IMPLEMENTATION

Building of National Power Consumption Management Center

Building of National Power Consumption Management Center is required to handle the data from different AMR systemsBuilding Power Management Center at the head office of PEPCOSoftware and hardware installation for different DISCOs of PEPCO

objective of the project is to

build a Nation Wide standardized integrated power consumption system with “Uniform Data Protocol, Uniform Service Procedures, Uniform software & Uniform Application interfaces”.

Infrastructure & Working of Complete AMR System

PEL’s AMR System

Proposed Working of Complete AMR System

Data concentrator is installed on the transformer to collect data from Three Phase Whole Current & Single Phase static meters through PLCC. This data is then transmitted to HOST SERVER STATION through GPRS network

Industrial Meters directly transfer data over the GPRS network to the HOST SERVER STATION

Industrial meters are also installed on transformers to monitor energy supplied through each transformer. This energy is then compared with Sum of Energies of individual meters installed on the same transformer for monitoring of line losses and theft.

PEL’s AMR System

Proposed Working of Complete AMR System

HOST SEREVR STATION consist of FRONT END SERVER, DATABASE SERVER & WEB SERVER

HOST SERVER STATION is Integrated to the Billing System of the Utility

Customers can Directly Access their Billing Data using WEB SERVER
