Public Switched Telecom Network

• The only source at that time • Dependent on service provider

• Costlier

PLCC

• Dedicated & safe

• Part of Utilities own transmission

network

• No dependence on

service provider

• Ruled for years

• Now digital PLCC,

but same core technology

• Frequency congestion

• Limited band width

– Restricted data transmission

GETCO Experience

14:23

HF Radio

• Useful for long distance

• Disaster Management

(Massive earthquake in Kutch)

• Requires license

VHF

• Helped in natural calamities

(Massive earthquake in Kutch)

• Open mode

• No network jam

• No dependence on

service provider

• Simultaneous contact to many

users

• Very useful in Distribution System

for load management

• Requires license

• Up to limited distance

GETCO Experience

14:23

Micro waves

• Relatively low cost

• Wide bandwidth

• Requires License

• Requires Line of sight

• Weather dependent

Satellite Phone

• Disaster Management

(Massive earthquake in Kutch and

flood in Surat)

• Useful for long distance

• Requires License

• Costlier

Leased copper lines

• Wide bandwidth

• More reliable• Dependent on service provider

3rd Generation

Fiber Optics - FO cables in Ground wire

OPGW

• No limitation in band-width –

huge transmission capacity

• Part of Transmission line -

Utilities own network

• Immune to interference

• No dependence on service provider

• Provides sufficient reserve capacity

to accommodate future expansion

30

GETCO Telecom Plan and Strategy

• Phasing out 1st & 2nd generation with 3rd generation technologies

• Installing OPGW on all new 400KV lines for Communication,

Protection, Control and SCADA (Digital Sub stations).

• Installing OPGW on strategic transmission network to provide

business opportunities.

• Developing communication network for WAMS

Ownership basis

Hiring basis.

• Going for GPRS connectivity for remote ABT meter reading.

• Opportunities from the transmission assets & business (consolidating

transmission assets into business units)

• Offering fiber and bandwidth on lease basis

Expectations from the telecom solution providers

• More manufacturers and suppliers should participate.

• It must be scalable.

• Modular design.

• IEC 61850 based Tele protection unit.

• Inter operability.

• Cost Effective
