AMR (Automatic Meter Reading)

Every Utility / Discom is fighting to find a solution for this problem

PROBLEMS

• Protocol

• Communication Ports

• Existing Meters

• Technology

• Implementation Time

• Few More

PROBLEMS

• ProtocolNo common, Standard / open protocol

is available in the energy meters available nor the meters which are being purchased.

Standard Protocol :-

• PACT (Multi dropping not possible)

Open Protocol :-

• Modbus ( Values are integers have to use

multiplying factor at software end)

• IEC 101 (No known meter available)

PROBLEMS

• Communication PortNo common type of port is available in the

energy meters available nor the meters which are being purchased.

The mixture of Optical, RS-232 and RS-485 is available and none has the record of the ports.

Recommended :-

RS-232 for the meters installed individually

RS-485 for the meters installed in groups (Substation, Group Metering)

PROBLEMS

• Existing MetersAs these meters vary in technologies, makes, Protocols, communication ports, etc. which creates a difficult situation for AMR implementation teams.

Recommended :-

Request the manufacturer to take back old meters and replace with new ones, as in many a cases it is only firmware up-gradation or minor modification.

PROBLEMS

• TechnologyAs these meters vary in technologies, makes, protocols, communication ports, etc. which creates a difficult situation for AMR implementation teams.

Recommended :-

Request the reshuffle / change energy meters to create the situation for the AMR supplier to opt. one technology / methodology for the system.

Example : Change all substation meters with the ones having RS-485 port & Modbus protocol.

PROBLEMS

• Implementation TimeAs these meters vary in technologies, makes, protocols, communication ports, Multiplying factors etc. which creates a difficult situation for AMR implementation teams.

Recommended :-

Request the reshuffle / change energy meters to create the situation for the AMR supplier to opt. one technology / methodology for the system.

This will reduce the AMR implementation time drastically.

Field Side

GPRS FOR SUBSTATION AMR

GPRS

•General Packet Radio Service•Wireless packet data channel•Based on GSM technology and networks•Designed for TCP/IP traffic•Dynamic radio channel allocation•Faster data transfer compared to GSM data•Public network, Global - low initial investments

GPRS Arctic Key Features

• Industrial grade GPRS router• Expands Ethernet devices over GPRS network• Easy and quick to install• Firewall and VPN for secure communication• 10/100 Base-T Ethernet connection• Mobile operator independent static IP addressing with Viola M2M Gateway

HardwareProcessor Environment32 bit RISC processor8 MB FLASH memory32 MB SDRAM memory

Power6 – 26 VDC nominal input voltage1 – 5 W power consumptionResettable fuse and ESD protection

OtherTemperature sensor, real time clock Environment

Temperature ranges:–20 to +70 °C–30 to +85 °C (storage)Humidity 5 to 85 % RH

Key Features

Configuration and Management : The Arctic GPRS Router is configured using a www browser. A conventional console interface is also provided. The software of Arctic GPRS Router can be updated over the network.

Network Protocols :PPP, IP, ICMP, UDP, TCP, ARP,DNS, DHCP, FTP, TFTP,HTTP, SNMP, POP3, SMTP

Tunneling (VPN) :SSHv2 server and clientSSHv1 server and client

Communication Protocols :Modbus, Modbus Ethernet, Transparent Mode, IEC 101, IEC 104, etc

EDGE

•Enhanced Data rates for GSM Evolution•EDGE is update for GPRS, also referred as EGPRS•More efficient radio modulation than in GPRS (8-PSK)•Speed is about 3-5 times more than in GPRS•236.8 kbit/s for 4 timeslots and theoretical maximum is 473.6 kbit/s•Uses same base stations and core network as GPRS/GSM, easy and cost-effective for operators•Typical download speed about 15 kilobytes/s
