Scope of the project

• GOAL : To deploy advanced meters together with new PLC techniques for improving metering management and network distribution automation

• SITE: Modern housing project in Bilbao

• SIZE: 1,100 meters and 8 transforming centers

• TECHNOLOGIES APPLIED : Advanced multifunction digital meters with PLC “A” band communication

• PARTNER:

10

• metering subsystem

• communication subsystem

• data acquisition subsystem

Architecture

11

• Digital A+R class 1 single and three-phase meters

• TOU and load profile functionality

• Built-in PLC modem

• Built-in automatic programmable breaker

Metering subsystem

12

Communication subsystem

•Transforming center concentrator TCC

•Automatic identification and registration of new installed meter

•Meter polling for reading data acquisition

•Meter time synchronization

•Inductive coupling

•Link between low and medium voltage carriers

•Substation data manager

•Data concentrator

•TCC management

•Sends meter data to billing center

•Sends control data to SCADA

13

Set of SW applications and tools to:

• transmit data over the powerlines

• reading and programming the concentrators and the data manager

• interface with the existing billing systems

Data acquisition subsystem

14

• DISTRIBUTION AUTOMATION

• Fault location and service restoration functionality

• TC CONTROL

• Status of breakers

• Transformer continuous monitoring

To be implemented in 2006

Enhancement of the AMM project

15

• Meters, concentrators, couplings in service

• System in full operation since July 2005

Status of the project

16

Future deployments plans

• Select more sites during 2006 with different environments:

• Urban areas with brand new housing

• Urban downtown areas

• Rural areas

• Increase number of meters to various thousand units in 2006

• Selective implementation of distribution automation and TC monitoring functionality

17

Lessons learned

Remote reading is not enough!

Standards are strongly recommended!

Real possibilities for Load Control and Demand Side Management policies

What are the benefits for the customer ?

18

• Technology is stable and reliable

• Lack of Standards

• Analysis of Field results• technical• savings compared to traditional

meter reading

• Service continuity

• Regulatory issues

• metering activity costs must be covered

• customers to receive price signals

• ownership

Conclusions
