Smart Grid Telecommunications Network Requirements

Metering, Billing/CRM Asia 2013, 22-23 May, Bangkok, Thailand 7

Telecommunications Strategy

Metering, Billing/CRM Asia 2013, 22-23 May, Bangkok, Thailand 8

Use internal network infrastructure – pilot cables, fibre optics

– Fibre optics network for backbone traffic – SDH, DWDM

– IP MPLS data network for data

– Separate network for critical real time applications – teleprotection, PMU, IEC61850, SCADA

Build & Operate private access network

– AMI Network • RF Mesh for dispersed residences/premises

• PLC for dense residences/apartments/condominiums

– DA Network • Licensed/Unlicensed wireless network

Use public network when internal networks unavailable

Use single integrated network for AMI, SCADA, DA etc

Monitor/manage network 24X7 from NOC

Outsource operations/maintenance

Network Technology Platform

• Teleprotection

• SCADA (Telecontrol)

• Voice services for grid systems operations

• Legacy applications

• PMU/Synchrophasor/WAIS

• IEC61850

IP/MPLS Network Utility SDH

Wireless Network: Public vs Private

Metering, Billing/CRM Asia 2013, 22-23 May, Bangkok, Thailand 10

• No SLG/SLA

• Unreliable for control applications

• Designed for mass public requirements

• Catered for mobile communications, broadband, social networking, internet access, gaming etc

• Unsuitable for legacy low bandwidth services

• Cost effective for small deployment

• Utilities tied down with telco technology lifecycle

Licensed Wireless Network

• Higher reliability

• Suitable for control applications

• Designed for utility legacy and low bandwidth applications

• Cost effective for large deployment

• Longer life cycle

• Frequency and license availability and constraints

License Free Wireless Network

• Cost effective solution

• Self healing technology

• Suitable for non control applications

• Subject to interference
